As the temperature drops and winter approaches, it’s not just your car’s engine that needs extra attention. Your car’s key fob is also affected by the cold weather, and it’s important to understand how frigid temperatures can impact its performance. In this article, we’ll explore how cold weather can affect your key fob and what you can do to prevent it from causing you frustration during the colder months.

How Cold Weather Affects Your Key Fob

Key fobs are small electronic devices designed to make our lives easier. They allow us to lock, unlock, and start our cars without ever having to take the key out of our pocket or bag. However, like any electronic device, key fobs are sensitive to extreme temperatures.

When the temperature drops, the battery inside the key fob can be affected. Cold weather causes the battery’s chemical reactions to slow down, which can lead to a reduced charge or even a complete failure to operate. If your key fob suddenly stops working or becomes unresponsive, it's likely due to the cold weather affecting the battery's ability to function properly.

In addition to battery performance, the cold can also cause the internal components of the key fob to contract. This may interfere with the fob’s functionality, causing it to not respond when you press the buttons. Furthermore, moisture from snow, rain, or condensation can get into the fob, which can cause short circuits or further damage.

Signs Your Key Fob May Be Affected by the Cold

If you live in an area where cold temperatures are common, it’s essential to be aware of the signs that your key fob might be struggling with the weather. Here are some indicators that the cold is affecting your key fob:

  • Unresponsive buttons: If you press the buttons on your key fob and nothing happens, it may be due to the battery or the internal components not responding correctly to the cold.
  • Delayed reactions: If you notice a delay in your fob’s response, where the locks or alarm take longer than usual to react, this is another sign of cold-induced malfunction.
  • Reduced range: If your key fob is working, but only from a very short distance, it could be due to the battery’s reduced performance in the cold.

If you notice these issues, don’t immediately panic. There are simple fixes and preventative steps you can take to resolve the issue.

What You Can Do to Protect Your Key Fob in the Cold

Fortunately, there are several things you can do to ensure that your key fob continues to work properly during cold weather. By taking a few precautions, you can protect the battery and internal components of your key fob from extreme temperatures:

Keep Your Key Fob Warm
One of the easiest ways to prevent cold weather from affecting your key fob is to keep it warm. If you're going outside during cold weather, keep your key fob in your coat pocket or a warm, insulated area. 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.

Top 10 Fascinating Facts About BMW: Engineering Precision, Motorsport DNA, and Driving Pleasure

Top 10 Fascinating Facts About BMW: Engineering Precision, Motorsport DNA, and Driving Pleasure

BMW stands for precision engineering and pure driving pleasure. Founded in 1916 in Bavaria, BMW began as an aircraft engine manufacturer before reshaping the automotive world. Its guiding philosophy, “Aus Freude am Fahren” (Sheer Driving Pleasure), has defined the brand for decades. Today, BMW builds everything from electric city cars to high-performance M models. What connects them all is balance, control, and a driver-first mindset. These BMW facts reveal how the brand earned its reputation. 1. Munich’s Four-Cylinder Headquarters BMW’s headquarters in Munich is instantly recognizable. The building, completed in 1972, resembles four vertical engine cylinders joined together. BMW’s headquarters in Munich is instantly recognizable. The building, completed in 1972, resembles four vertical engine cylinders joined together. 2. Logical Model Names Since 1972 BMW’s naming system is deliberately simple. Introduced with the first 5 Series in 1972, the three-digit structure tells you exactly where a model sits in the lineup. The first number shows the series. The remaining digits traditionally indicated engine size. Letters like i , d , and x were later added to explain fuel type or drivetrain. BMW drivers can often decode a car before even opening the door. 3. The Only BMW With a Real Name Almost every BMW uses numbers—except one. The BMW Isetta remains the brand’s only mass-produced car with a proper name. Licensed from Italian manufacturer ISO in the 1950s, the Isetta featured a single front-opening door and ultra-compact dimensions. It helped BMW survive financially after the war and became a design icon in Europe. 4. Motorsport DNA: The Birth of BMW M BMW’s M division was created in 1972 to support racing programs. Its purpose was simple: win races and transfer that knowledge to road cars. BMW M cars quickly became benchmarks for performance sedans and coupes. The connection runs deep—BMW even powered a Formula 1 championship-winning car in 1983. Motorsport is not branding for BMW; it’s engineering validation. 5. Safety Innovations Ahead of Their Time In 1972, BMW revealed the Turbo concept car. It introduced ideas that would later become industry standards. Crumple zones, energy-absorbing steering columns, and even early collision-warning concepts were present. Decades before modern driver-assist systems, BMW was already testing how to protect drivers without compromising performance. 6. Hydrogen Engines in the 1970s BMW experimented with hydrogen power long before electrification became mainstream. In 1979, BMW tested a hydrogen-powered 5 Series sedan. The car looked ordinary but ran on modified combustion technology. This early project showed BMW’s willingness to explore alternative energy paths well ahead of regulations or market demand. 7. Project i and the Electric Breakthrough BMW’s modern electric strategy began in 2007 with Project i. The initiative was designed to rethink mobility from scratch. The result was the BMW i3, launched in 2013. It combined carbon-fiber construction, electric drive, and sustainable materials. Project i shaped BMW’s current EV lineup and proved electric cars could still deliver driving pleasure. 8. Limited-Run BMW Special Models BMW frequently builds rare, limited-production vehicles to showcase design and engineering freedom.

These cars often sell out instantly, reinforcing BMW’s reputation for exclusivity and craftsmanship. 9. Precision Manufacturing With BMW iFACTORY BMW applies the same precision to manufacturing as it does to driving dynamics. The BMW iFACTORY concept integrates AI, robotics, and digital twins into production. Quality control is automated and continuously monitored. The result is consistent build quality across plants in Europe and beyond—something BMW drivers notice long after purchase. 10. Steering-Wheel Controls Before Anyone Else BMW introduced steering-wheel-mounted controls in the early 1990s. Inspired by Formula 1, the goal was simple: keep the driver’s hands on the wheel. Functions like audio and cruise control became easier to manage. Today this feature is universal, but BMW was among the first to make it standard in luxury cars. FAQ What does BMW stand for? BMW means Bayerische Motoren Werke (Bavarian Motor Works). The company was founded in Munich in 1916 and originally produced aircraft engines. Why do BMW drivers value the brand so highly? Balance, rear-wheel-drive heritage, motorsport DNA, and consistent engineering philosophy all contribute to BMW’s loyal following. What should you do if you lose your BMW key? BMW keys are coded and must match the vehicle’s security system. Owners usually replace them through dealers, but specialist suppliers can also provide compatible keys and cases . Platforms like MR-KEY help BMW owners replace worn or lost keys while maintaining proper ownership verification. Visit our shop at mr-key.com

What You Need To Know About BMW  Swirl Flaps and How To Solve The Problem With Them

Swirl flaps are a BMW system that has been introduced to help burn the fuel mixture in the cylinder better due to the fact that diesel engines do not have throttle valves and it is not possible to adjust the air-fuel ratio. A diesel engine without vortex valves operates between a poor and a rich fuel mixture, because the only way to regulate it is through fuel injection. Design of the first generation swirl flaps that are made of made of metal. Unfortunately, swirl flaps are responsible for countless damaged engines and costly repairs due to design errors or metal fatigue. Once damaged, the cylinder sucks them in and causes great damage. This is how damaged valves damage the cylinder. Typical swirl flaps suction damage. The vortex valves are positioned in the inlet and are controlled by vacuum (DDE 4.0) or electrically (DDE5.0 / DDE6.4) by the engine ECU. Effects of malfunctioning valves: Swirl valves are stuck in open position: Deterioration of exhaust gas performance at lower speeds. Swirl valves are stuck in closed position: Approximate power loss of 10% at high engine speeds. How swirl flaps work: Performance characteristics: The vortex valves are in the closed position, at low engine speeds and small amounts of fuel injected (controlled by the ECU card). They open under the following conditions: coolant temperature <14 ° C OR * fuel quantity> 24 mg OR 2. engine speed 2250 rpm OR 3. inlet air temperature <-5 ° C. BMW and Pierburg have decided to produce diesel engines with metal vortex valves. The speed at which the pistons in the diesel engine operate is at least 60 rpm, so a sucked vortex valve will break and cause a number of damages inside the engine. In most cases, one or more pistons are severely damaged, as a bonus you get valves, in some cases a head or turbocharger. And this combination with a BMW engine is like a cumulative jackpot 🙂 In 2004, BMW began work on the problem and improved the design, however, a number of owners reported ongoing problems in this area. The solution to this problem is by removing the vortex valves and plugging, which does not affect the performance of the engine and at the same time, you can safely pass the exhaust test. Engines: M47 (136hp VP44 fuel pump) has no valves. M47N common rail engine (including M47N / M47TU / M47TUD20) (150hp. Face lift model from 2001 -) has valves. M57 engines (M57D) (525d & 187hp. 330d) cars with manual transmission do not have valves, but those with automatic have. M57N engines (M57TUD) (525d & 330d 204hp) have vortex valves. Ruined swirl flapss: The plugs that replace the vortex valves are easy to find on the internet, but you can also find them here on our website. Typical plugs: Disassembly of vortex valves: The vortex valves can be safely dismantled and in most cases if they are removed properly no loss of power is felt.
