Dead Coin Battery
A dead coin battery is among the most common reasons for the keys for the seat to cease to function. The key fob is powered by a small button-cell battery.

Faulty Receiver Module
If your key fob stopped working after replacing the battery but it did not function, or stopped working in a sudden manner your receiver module might have experienced a malfunction.

Connect the battery in reverse (negative cable to positive first). This will reset all the electronic components onboard and bring them back to their original functionality.
Faulty electronic chip
