Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it didn't work, or if it stopped working suddenly the receiver module could be experiencing a problem. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands 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 issued by your remote key fob. In this scenario it is necessary for a dealer to reprogramme your key fob, and also install an entirely new receiver.
The key fob has been sealed with rubber to keep water from entering the electronic chip. If you dip the key fob into salty or soapy water, it could cause damage to the chip. If your key fob won't work, try cleaning the chip with isopropyl or electronic cleaner.
If the keys are in a pair but the receiver module has developed a fault you can try restarting all the on-board electronics by removing the battery at 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset all the on-board electronics and should restore their functionality.
Electronic Chip Faulty
The key fob comes with a chip that transmits an indication from the key to the receiver module each time the key is used. If the signal does not match the one that the car has stored the immobilizer will turn off and prevent the vehicle starting. If the key fob isn't functioning and you cannot reprogram it then it could be due to a malfunctioning chip.
The chip inside the key fob isn't an irreplaceable part of the device, and might need to be replaced to get it working again. This can be accomplished by removing the key fob from its housing, and then using a needle or pin to connect with each metal retaining clip. If these clips are damaged or damaged, you'll require replacement to allow the remote control to function. Make sure that the replacement batteries are the same size, voltage and specifications as the original one.
