Check what still works. Before transferring electronics, identify every component and confirm the replacement shell.
Our method
- Check the simplest cause.
- Compare a working spare when possible.
- Verify before ordering a replacement.
A broken housing can sometimes be solved without replacing the electronics inside the key.
Reshelling may make sense when
- The remote functions still work.
- The circuit board appears undamaged.
- The problem is mainly the outer case, button pad, hinge, or key-ring area.
Be careful with transponders
Some keys contain a separate immobilizer transponder that can be small and easy to overlook. Losing or damaging it during a case transfer can leave you with a remote that locks the doors but will not start the vehicle.
Best practice
Photograph the original key before disassembly and move only the components that belong in the verified replacement shell. If you are unsure which component is the transponder, stop and use a qualified professional.
