Locate the alphanumeric code stamped on your Momentum original key shaft or bow and match it to the product listing. The code is on the original key only — not on the Momentum lock body.

Every Momentum replacement ships cut to your exact code — no programming, no locksmith, no tools needed after delivery.
Products
I searched for Momentum bike lock keys — am I in the right place?
Yes. Every product on this page is a Momentum replacement bike lock key ordered by code. The page is filtered to Momentum only — no other brand keys appear here. Each listing matches a specific Momentum lock cylinder code. Find the code on your original Momentum key shaft, select the matching product, and your replacement ships cut to that exact code.
Can I use a replacement Momentum bike lock key on a different brand lock?
No. A key cut to a Momentum code operates Momentum cylinders only. The blade profile is specific to Momentum lock internals — the same code on a different brand lock will produce a different blade profile. Physical similarity in key shape between brands is coincidental and does not indicate cross-brand compatibility.
Where exactly is the code on my Momentum bike lock key and what does it look like?
The code is stamped on the shaft or bow of your original Momentum key — it is a short alphanumeric sequence, not a serial number or barcode. It is not on the lock body. If dirt or wear makes it hard to read, hold the key under a torch at an angle — the stamping reflects light differently from the surrounding metal. If still unreadable, photograph the key and send it to mr-key.com — partial codes can often be identified from the image.
I have the code from my original Momentum key — what do I do next?
Enter the code exactly into the drop menu on the correct Momentum product listing on this page. Double check it matches before adding to cart — one digit wrong means the wrong blade profile. Once confirmed, complete the order. Every Momentum replacement on this page ships cut to that exact code before dispatch — no cutting after delivery, no programming, no locksmith visit required.
All my Momentum bike lock keys are gone and I never noted the code — what now?
Without the code, a Momentum replacement cannot be ordered from this page — the code is on the original key only, not on the lock body. The only way to retrieve it is to have a locksmith physically decode the Momentum lock cylinder. Once the locksmith provides the code, return to this page and order using the drop menu. If you have a photo of the original key with any stamping visible — even partial — send it to mr-key.com before calling a locksmith.
