Quick answer: To replace a lost Mountain Top roller shutter or truck canopy key — found on Ford, Nissan, Isuzu and other pickups — order a new key cut to the 7U code stamped on your lock or original key (range 7U1000-7U3999). Both the exact code and a clear photo of your existing key are required to cut a guaranteed-correct match, which Mr-Key.com supplies ready to use.
What a Mountain Top roller shutter key is
A Mountain Top roller shutter key is the small flat key that locks the cover over a pickup's load bed — whether that is a retractable aluminium roller shutter or a hard truck canopy (and its external handle or van-security latch). It is cut to a Eurolocks cylinder code in the 7U series — printed as 7U followed by four digits, for example 7U1010 — and that code, not the truck model, is what defines the exact key.
This key fits the keyed version of the cover: the Mountain Top Roll "Classic" (manual cover with an external key lock and handle) and Ford's factory-badged "Red Rock" variant, built around Mountain Top's retractable Roll covers. It is not used on the EVOm cover (no external lock) or the EVOe cover (electric, opened by a remote fob), which is covered under compatibility below.
How to find your 7U key code
Your 7U code is stamped on your original key or on the lock barrel. It reads as 7U plus four digits and falls within the range 7U1000-7U3999. You only need to read this number to order — you do not need the lock removed.
Where to look
- On the original key: check the bow (the flat head you grip) and the shoulder of the blade for the stamped 7U number.
- On the lock: look at the face of the lock barrel behind the external handle of the roller shutter, where the code is often etched.
- On any spare or paperwork: a second key, the original handover documents or the cover's fitting paperwork may list the same 7U number.
Code worn or unreadable? Photograph both sides of the key in good, even light and contact us before ordering. We can often confirm the series from the key profile and the visible digits, then verify the exact code with you.
How to order a replacement in 3 steps
Ordering takes three steps and no special tools: select your exact 7U code, upload a photo of your original key, and check out. We cut the blade to that code and post it ready to use — there is no programming and no locksmith visit.
- Select your exact 7U code. Choose your code (for example 7U1010) from the dropdown on the product page. It must match the number stamped on your key or lock.
- Upload a clear photo of your key. Add a sharp, well-lit photo of your original key (or the lock face if you have no key). This is required, not optional.
- Check out and we cut to code. We machine the blade to your 7U code, verify it against your photo, and dispatch a finished key that works straight from the envelope.
Both the code AND a photo are required — here is why The 7U code tells us the exact bitting to cut. The photo lets us verify that your key is the genuine Eurolocks/Mountain Top 7U profile (not a similar-looking lookalike) and that the stamped code has been read correctly. With both, we never cut the wrong key. An order with only one of the two cannot be processed.
When this key is not the right part
If your cover is a Mountain Top EVOm (no external key lock) or EVOe (electric, opened by a remote fob), or a different brand such as Roll-N-Lock or another roller shutter, this 7U key will not fit — those use a different locking system. Send us a photo if you are unsure and we will point you to the correct part.
Which pickups and locks this key fits
This key fits Mountain Top Roll (Classic) roller shutter covers, truck canopies and van-security locks built on matching Eurolocks barrels coded 7U1000-7U3999, including Ford's "Red Rock" version. The cover is commonly fitted to the pickups below — but your 7U code is the decisive factor, not the badge on the truck.
| Brand | Lock / key code |
|---|---|
| Ford | 7U code |
| Nissan | 7U code |
| Isuzu | 7U code |
| Eurolocks | 7U code |
The same Mountain Top Roll cover and 7U lock appear on other pickups too, so the rule is simple: if your lock or key carries a code between 7U1000 and 7U3999, this is your key, whatever the vehicle.
Outside the 7U1000-7U3999 range? A code that does not start with 7U, or one outside 7U1000-7U3999, belongs to a different lock series. Do not order on the truck brand alone — send us a photo and the code first and we will confirm the right key.
Frequently asked questions
Can you cut a Mountain Top key from just the code, without a photo? No. Both are required: the 7U code sets the exact cut, and a clear photo lets us confirm your key is the genuine Eurolocks 7U profile and that the code reads correctly, so you never receive the wrong key.
Does a Mountain Top roller shutter key need programming or a locksmith? No. It is a purely mechanical key with no chip or transponder, so it arrives cut to your code and works immediately. No programming, locksmith visit or special tools are required.
Where do I find my 7U key number? Your 7U number is stamped on your original key or on the lock barrel behind the handle, shown as 7U followed by four digits within 7U1000-7U3999. Select that exact code when you order.
What if my code is outside 7U1000-7U3999, or the key still does not fit? A code outside 7U1000-7U3999 belongs to a different lock series, so send us a photo before ordering and we will confirm it. If a correctly coded key fails to work, we replace it or refund you.
