Dead Coin Battery

A dead coin battery is one of the most frequent causes for the keys for the seat to stop working. The key fob contains a small button cell battery that is able to keep it powered. Replace it with a new battery that is the same voltage, size and specification as the original. When replacing the battery on the key fob, remove the metal clips and make sure that the contacts on the key fob are in good condition and free of corrosion.

Faulty Receiver Module

If your key fob stopped working after you replaced the battery and it did not help, or if it just stopped working without notice the receiver module might have developed a fault.

If the keys are connected, but the receiver module is malfunctioning, you can try to restart all the electronics that are on board by disconnecting the 12-volt battery for a couple of minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality.

Electronic chip that is malfunctioning

The key fob contains tiny electronic chips that sends a signal to the receiver module whenever the key is used. If this signal does not match that stored by the car, the immobilizer will disable the engine and prevent the vehicle from starting. However, if the fob isn't functioning and you are not able to reprogram it this could be due to a defective chip.

The chip inside the key fob is not an indefinite part of the device and may need to be replaced in order to function again. This can be accomplished by getting the key fob removed from its housing and using a needle or pin to connect with each metal retaining clip. You will require replacement in the event that they have been damaged or corroded. Make sure that any replacement batteries are the same voltage, size and specifications as the original one.
