Dead Coin Battery A dead coin battery is one of the most frequent reasons for the keys for the seat to stop working. The key fob is powered by a small button-cell battery. Replace it with a brand new battery with the same size, voltage and specifications as the original. When replacing the battery on the key fob remove all metal clips and ensure that the contacts of the key fob are clean and free of corrosion. If the key fob was exposed to water (such as rain or soapy tap water), it is recommended that you remove and clean the chip using an electronic cleaner or isopropyl alcohol prior to installing a new battery. The chip can be permanently damaged by water. If the key fob still not working after replacing the battery, it might be necessary to replace the entire key fob. Faulty Receiver Module If your key fob was not working after replacing the battery but it didn't work, or if it stopped working in a sudden manner the receiver module could be experiencing a problem. The receiver module is able to receive radio frequency signals from your remote keyfob and transforms them into electrical signals that are then followed by other modules inside the car. If the receiver module has suffered a malfunction it will not respond to any of the commands transmitted by your remote key fob. In this case it is necessary for a dealer to reprogramme your key fob, and also install an entirely new receiver. The key fob is sealed with rubber to prevent water from leaking into the electronic chip. If you immerse your key fob into the ocean's salty or soapy water, the chips inside may be damaged.

If the keys are paired, but the receiver module is not working it is possible to restart all the electronics on board by disconnecting the battery at 12 volts for couple of minutes. Then reconnect the battery in reverse order (negative cable first, then positive). This will reset the on-board electronic and restore their functionality. Electronic Chip Faulty The key fob is equipped with a tiny chip that transmits a signal from the key to the receiver module each time the key is used. If the signal doesn't match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. If the key fob you purchased does not work and you aren't able to reprogram it, it could be because of an incompatible microchip. The chip inside the key fob may need to be altered to allow it to function again. The most effective method for doing this is by removing the key from its housing and using a pin or needle to contact each of the metal retaining clips. If the clips are corroded, or broken, you will require replacement to allow the remote control to work.
