Repair Path: Shell replacement. This is an affordable repair. One can acquire a "blank" shell, move the internal circuit board and transponder chip to the brand-new housing, and have the brand-new blade cut to match the initial.
3. Internal Electronic Failure
If the buttons no longer lock or open the doors, but the battery is fresh, the internal circuitry may have a broken solder joint or a stopped working part.

Repair Path: Circuitry repair or reprogramming. Experts can often resolder loose battery terminals or buttons. However, if the PCB is fried, a new set key is needed.
