Post Name
29.01.2025

Regular lock maintenance is essential to prevent key jamming or lock failure. Proper lubrication reduces wear and tear, ensures smooth operation, and extends the lifespan of your locks. A well-lubricated lock decreases the risk of your key getting stuck or breaking inside the lock—an inconvenient and costly problem. At MR-KEY, we understand the importance of well-maintained locks and want to help you keep yours in top condition.

 

How Often Should You Lubricate Your Locks?

 

For most locks, lubricating them every three to six months is sufficient. However, locks exposed to extreme weather conditions—such as those on towbars, roof racks, or outdoor gates—require more frequent maintenance. Rain, dust, and freezing temperatures can cause internal components to stick, making it difficult to insert or turn the key. If you notice resistance when using a lock, it’s time for lubrication.

 

What Lubricant Should You Use for Locks?

 

Choosing the right lubricant is crucial for long-term lock performance. Here are the best options:

• Teflon-based (PTFE) spray – Forms a protective film inside the lock, reducing friction and repelling dust buildup.

• Dry silicone spray – Excellent for outdoor locks as it resists moisture without attracting dirt.

• WD-40 Specialist Dry PTFE or White Lithium Grease – Unlike regular WD-40, these provide long-lasting lubrication and protection against corrosion.

• Graphite powder – A great choice for older locks but should not be used if there’s oil residue inside the lock.

 

While WD-40 Multi-Use is a quick fix for stuck locks, it is primarily a cleaner rather than a long-term lubricant. If used, follow up with a dry lubricant to prevent dirt accumulation inside the lock.

 

How to Lubricate a Lock

 

If your lock is functioning properly but feels slightly stiff, follow these steps:

1. Clean the Lock – Insert and remove the key a few times to dislodge debris, wiping it clean each time.

2. Apply the Lubricant – Insert the spray straw into the keyhole and apply two short bursts of lubricant.

3. Work the Lock – Insert and turn the key multiple times to distribute the lubricant inside.

4. Wipe Excess Lubricant – Remove any residue from the key and lock exterior to prevent dirt buildup.

 

For graphite powder, follow the manufacturer’s specific instructions, as overapplication can lead to clumping inside the lock.

 

Special Care for Towbar and Roof Rack Locks

 

Locks on towbars and roof racks are exposed to harsher conditions than typical door locks. To keep them in good shape:

• Regularly inspect them for stiffness or corrosion.

• Apply dry silicone spray or PTFE lubricant for lasting protection.

• If the lock is exposed to frequent moisture, white lithium grease offers superior water resistance.

 

Lock It in: The Key to Long-Lasting Security

 

Regular lock maintenance is a small effort that prevents big problems. By keeping your locks clean and properly lubricated—especially those exposed to the elements—you can avoid costly repairs and ensure they function smoothly for years.

Car Ignition Switch Problems: Symptoms, Causes, and Replacement Guide

The ignition switch is one of the most important electrical components in any car. When it starts to fail, the symptoms can appear suddenly, seem unrelated, and quickly leave you stranded. This guide explains the real-world signs , the common causes , the most accurate diagnosis steps , and a clear ignition switch replacement guide that helps any driver understand what’s happening and what to do next. If you’re dealing with car ignition lock problems , this article gives you the clarity you need to fix the issue fast and safely. What the Ignition Switch Actually Does The ignition switch has two critical jobs: 1. Electrical power distribution It sends power to the dashboard, fuel pump, ignition system, starter motor, and electronic modules. 2. Starting the engine When you turn the key (or press the button), it bridges electrical circuits, enabling the starter motor to crank the engine. When the ignition switch begins failing, even slightly, it disrupts these circuits. That’s why symptoms can range from flickering dash lights to complete engine shutdown. Symptoms of a Failing Ignition Switch These are the most common, proven symptoms that mechanics use to identify ignition switch problems. 1. Car Won’t Start or Cranks Intermittently If turning the key does nothing—or the engine cranks sometimes but not always—the ignition switch may not be sending power consistently to the starter relay. Typical behavior includes: Silence when turning the key Clicks but no cranking Starts only after multiple attempts Total power loss during cranking This is one of the most classic ignition switch symptoms. 2. Stalling While Driving A failing ignition switch can cut power to the engine while you’re moving . Common signs: Sudden stall for no reason All dash lights go off instantly Engine dies when hitting bumps Engine cuts out but restarts immediately This is dangerous and needs urgent attention. 3. Dashboard Lights Flickering or Turning Off When the internal contacts inside the switch wear out, they create tiny power interruptions. You may see: Speedometer drops to zero Warning lights randomly appear Interior electronics momentarily cut out Radio resets or flickers These short power losses are a major red flag. 4. Key Feels Hot or Hard to Turn If the key is warm after driving, the switch may be overheating internally. If the key becomes difficult to rotate, the ignition cylinder (mechanical part) may be worn — which often leads to switch failure later. 5. Accessories Don’t Work in ACC Mode If turning the key to ACC does not activate: radio wipers power windows heater fan …the accessory circuit inside the switch may be failing. 6. No Sound from the Fuel Pump When Turning the Key You should hear a soft humming for 1–2 seconds. If you don’t, it may mean the ignition switch isn’t powering the pump relay. What Causes Ignition Switch Problems? Ignition switches fail for predictable and well-documented reasons. 1. Internal Wear Over Time Inside the ignition switch are metal contact plates . After thousands of cycles, these contacts burn, corrode, or lose tension. Symptoms develop slowly: random stalling needing to wiggle the key intermittent power This is the most common cause. 2. Heavy Keychains Many drivers don’t realise this: A heavy keychain constantly pulls on the ignition cylinder. Over years, this causes: internal looseness misalignment premature switch failure If your keychain has more than a few items, it may be contributing. 3. Heat and Electrical Overload Faulty relays, worn fuel pumps, or aftermarket accessories can overload the ignition switch. Excess heat damages the internal copper contacts, causing: hot key symptoms partial circuit failure total switch burnout 4. Moisture or Dirt in the Cylinder Moisture or dust causes the mechanical part of the ignition to jam or bind. This forces extra pressure onto the switch every time the key turns. 5. Faulty Key or Worn Key Blade If your key doesn’t rotate smoothly, it can damage both the cylinder and the switch . Worn keys often lead to electrical faults later. How to Diagnose Ignition Switch Problems Accurately Before replacing parts, you should confirm the ignition switch is truly the issue. These steps follow the same logic professional mechanics use. 1. Check if Dashboard Lights Turn On Turn the key to ON without starting the engine. If: no lights come on lights flicker radio stays off …the ignition switch might not be sending voltage. 2. Try Starting with Accessories On Turn the key to ACC. If the accessories work in ACC but the engine won’t start, the “start circuit” inside the ignition switch may be failing. 3. Wiggle Test Gently wiggle the key while: trying to start with ACC on with the engine idling If wiggling makes electronics turn on/off, the switch is internally worn. 4. Bump Test While Driving If the car stalls when hitting bumps or potholes, the switch is losing internal contact momentarily. This is one of the strongest indicators of a failing switch. 5. Test Voltage at the Ignition Switch (Advanced) Using a multimeter, check for: constant power switched power accessory power start signal power If any circuit fails randomly, it confirms an ignition switch fault. If you need a safety reference for electrical testing, you can check the UK Government’s general vehicle safety guidance here: Prevention: How to Avoid Ignition Switch Problems Ignition switch failures can often be prevented with small habits. 1. Keep Your Keychain Light Remove heavy accessories. This reduces stress on the ignition cylinder and switch dramatically. 2. Avoid Resting Hands on the Key While Driving Constant pressure on the key twists the internal contacts. 3. Only Use Correct, Undamaged Keys Bent, cracked, or worn keys can damage: the cylinder the switch the steering lock If your key is worn, replace it before it causes further problems. 4. Address Electrical Problems Early A failing alternator, weak battery, or short circuits can overload the ignition switch. If you notice dim headlights or battery warnings, fix those early. 5. Keep Dust and Moisture Out of the Cylinder Avoid spraying WD-40 or household lubricants into the ignition—it attracts dust. Use proper graphite lock lubricant if needed. Ignition Switch Replacement Guide You should only replace the ignition switch if diagnosis confirms it. Below is a clear replacement overview used by both DIYers and technicians. Note: Procedures vary by vehicle, but the overall steps are similar. 1. Disconnect the Battery Always disconnect the negative terminal. This prevents: accidental airbag deployment electrical shorts damage to modules 2. Remove Steering Column Covers Most cars use simple screws underneath. Once removed, the top and bottom covers split apart. 3. Locate the Ignition Switch Module It is usually mounted behind the ignition cylinder. Depending on the car: it may be held by two screws or secured with clips or integrated into a combined steering lock module 4. Remove the Electrical Connector Ignition switches usually have one large multi-pin connector. Release the locking tab and pull it gently. 5. Remove and Replace the Switch Install the new switch in the exact orientation as the old one. Common mistakes to avoid: misaligning the switch’s internal slot tightening screws unevenly damaging wiring during removal 6. Reassemble and Test Thoroughly After reassembly, test: ACC mode ON mode engine start headlights indicators wipers radio If everything works consistently, the replacement is successful. Is It Safe to Drive with a Bad Ignition Switch? Usually no . A failing ignition switch can: stall the engine suddenly disable power steering shutdown ABS cut power to headlights at night The RAC warns that electrical failures causing engine cut-outs are a serious safety risk. If your switch is failing, get it inspected immediately. FAQ: Car Ignition Switch Problems 1. How much does ignition switch replacement cost? Most replacements cost £80–£300 depending on the vehicle. Some modern cars require coding, making the cost higher. 2. Can a bad ignition switch cause the car to stall? Yes. Loss of electrical contact in the switch can cut power to the engine instantly. 3. Is a failing ignition switch the same as a bad starter? No. A bad starter prevents the engine from cranking. A bad ignition switch prevents power from reaching the starter or other systems. 4. Can a locksmith replace an ignition switch? In many cases, yes — especially for older vehicles. For modern immobilizer systems, a vehicle technician may be required. 5. Can I drive with ignition switch problems? It’s unsafe. The engine can cut out while driving, especially on bumps or turns. 6. Does a bad ignition switch affect accessories only? It can affect: accessories engine start fuel pump dashboard power ECU communication It depends on which internal circuit fails. 7. What’s the lifespan of an ignition switch? Most last between 10–15 years , depending on usage and electrical load. 8. Do push-button cars have ignition switches? Yes — they use an electronic ignition switch module instead of a mechanical one. Failure symptoms are similar. 9. What does a worn key have to do with ignition switch problems? A badly worn key can cause mechanical strain on the cylinder, which then stresses the electrical switch linked behind it. 10. Can I prevent ignition switch issues? Yes — keep your keychain light, avoid forcing the key, and keep electrical systems maintained. For high-quality replacement automotive parts and spare key, visit our shop at mr-key.com .

Understanding Key Fob Security: Protecting Your Vehicle

Understanding Key Fob Security: Protecting Your Vehicle

You use your key fob every day—locking and unlocking your car, maybe even starting the engine from a distance—without giving it a second thought. But as technology in vehicles advances, so do the methods used to compromise it. Keyless entry has made life more convenient, but it’s also introduced a new set of risks. If you’ve ever wondered how secure your key fob really is, or how you can protect yourself against modern car theft, this guide is for you. How Your Key Fob Works Key fobs operate by sending a low-frequency radio signal to your car. When the car recognizes the encrypted signal, it unlocks or starts the engine. It’s fast, wireless, and requires no physical interaction with the car—just proximity. Most modern fobs also use a rolling code system that changes the signal each time, making it harder for thieves to duplicate. This technology helps protect against basic forms of signal cloning, but “harder” doesn’t mean “impossible.” Criminals have found ways to bypass even these security measures. What Is a Relay Attack? One of the most common forms of key fob theft today is the relay attack. It relies on extending the communication range of your key fob without your knowledge. Here’s how it works: thieves use two devices. One person stands near your home, capturing the signal from your key fob—even through walls or windows. The second person uses a relay device to transmit that signal to your car. The car thinks the key fob is close and unlocks the doors. In some cases, they can even start the engine and drive off without ever seeing the key. All of this can happen in seconds. There’s no broken glass, no forced entry, and often no alarms triggered. By the time you realize something’s wrong, your vehicle might already be gone. Signal Jamming and Other Threats Relay attacks aren’t the only thing to worry about. Another tactic thieves use is signal jamming. This involves blocking the signal between your key fob and your car when you attempt to lock it. You might press the button and hear nothing unusual—but your car never actually locks. You walk away, thinking everything’s secure, while the thief simply opens the door and gains access. Then there’s code grabbing, which involves intercepting your key fob’s signal and replaying it later to unlock the vehicle. While more complex and less common, it’s another reminder that your key fob isn’t just a convenience—it’s a target. How to Protect Your Key Fob Fortunately, there are several effective ways to protect your key fob. Start by storing it away from exterior walls and windows. The closer your fob is to the outside of your home, the easier it is for thieves to pick up its signal. For stronger protection, use a Faraday pouch or metal container. These signal-blocking enclosures prevent any radio frequency from escaping, effectively rendering your fob invisible to relay devices. They’re inexpensive, easy to use, and highly effective. If your vehicle allows it, consider disabling the keyless entry feature when not in use—especially overnight or when your car is parked for long periods. You’ll usually find this option in your car’s settings or user manual. Make a habit of confirming your vehicle locks before walking away. Look for flashing lights or listen for the beep. These small checks can alert you if a jamming attempt has occurred. Be cautious with third-party or aftermarket fobs. Not all of them use reliable encryption or high-quality components. A poorly designed fob could introduce new vulnerabilities rather than protecting against them. Stay One Step Ahead Keyless technology is here to stay, offering undeniable convenience to drivers. But with that convenience comes a new wave of digital risks. Thieves don’t need to break windows anymore—they just need the right equipment and an unsecured signal. You don’t need to be a tech expert to protect yourself. Just understanding how your key fob works—and taking a few simple precautions—can significantly reduce your risk. Treat your fob like the digital key it is. Keep it protected, and you’ll keep your car safer, too. Because in today’s world, car security isn’t just about the locks—it’s about the signal.

You can even use a small pouch or key fob holder with insulation to protect it from the cold. Replace the Battery Before Winter If your key fob is already showing signs of battery issues, consider replacing the battery before winter hits. Even if it’s not quite dead yet, replacing the battery can help ensure that your key fob works smoothly during colder months. Many key fob batteries are easy to replace and can be done at home with a simple tool. Use a Backup Key If you anticipate being in extremely cold conditions or live in a particularly harsh climate, consider having a backup key. Many cars come with a traditional key hidden inside the key fob, which you can use if the key fob stops working in the cold. Having this backup can save you a lot of hassle if your fob stops working unexpectedly. Avoid Moisture Exposure It’s important to keep your key fob dry, especially in winter, when snow, rain, and condensation can cause moisture to build up inside. If your fob does get wet, dry it thoroughly as soon as possible and avoid leaving it outside in damp conditions. If moisture persists, it may cause the internal components to fail. Test Your Key Fob Regularly To ensure that everything is working properly, make a habit of testing your key fob regularly, especially during the colder months. If you notice any signs of malfunction early, you can address the issue before it gets worse. What to Do If Your Key Fob Stops Working If your key fob stops working despite taking preventative measures, don’t panic. There are a few things you can do: Warm up the Fob : Try warming up the fob by placing it in your pocket for a few minutes or rubbing it in your hands. This can help restore some functionality if the battery has slowed down due to the cold. Replace the Battery : If the fob still isn’t working, it may be time to replace the battery. A new battery can often resolve issues related to cold weather. Contact a Professional : If the fob continues to malfunction after changing the battery, it may be time to take it to a professional locksmith or the dealership to check for internal damage. While it’s easy to overlook the impact that cold weather can have on your car’s key fob, it’s important to understand the effects that extreme temperatures can have on its performance. By taking simple precautions and knowing the signs of potential issues, you can help ensure that your key fob continues to work smoothly throughout the colder months. From keeping it warm to regular maintenance, there are several ways to protect your key fob and avoid the frustration of a malfunction during the winter. So, this season, take a few extra steps to care for your key fob, and you’ll be able to unlock and start your car with ease, no matter how cold it gets outside.
