BMW key motorbike

thingiverse

All the original rubber on this key has worn off. But the key is not so simple inside. It has cavities where a chip is housed (the chip of the EWS), and this system of cavities is very fragile. You need all this to hold up well and not break. The hole in the middle is intended to be used as a security fastening (or second fastening) towards the keyring ring, since it passes through a metal hole on the inside. Thus, the rest of the key ring cannot be lost due to detachment in the face of strong vibrations. I leave the files also in Autodesk Inventor format so you can modify the design.
