If you are replacing the battery, ensure that you remove all metal clips from the back of the key fob. You should also make sure that the contacts are clean and free of corrosion.

If the key fob was exposed to water (such as soapy tap water) it is recommended to remove and clean the chip using an electronic cleaner or isopropyl ethanol prior to installing a new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob is still not working after replacing the battery, it might be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped functioning after replacing the battery, but it did not function, or stopped working in a sudden manner the receiver module may have experienced a malfunction. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob, and transform them into electrical commands that are then utilized by other modules in the car.

If the receiver module has suffered a malfunction, it will not respond to any of the commands received by your remote key fob. In this instance, a dealer will need to reprogramme your key fob and install an additional receiver.

The key fob is sealed with rubber to prevent water from entering the electronic chip. If you immerse your key fob in soapy water or salty ocean water, the chips inside could be damaged. If your key fob isn't able to function, you can try cleaning the chip with isopropyl or an electronic cleaner.

If the keys are paired but the receiver module has developed a fault you can try rebooting all the on-board electronics by disconnecting the 12 volt battery for a few minutes. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset the on-board electronic circuits and restore their functionality.

Faulty Electronic Chip

The key fob is fitted with a tiny chip that transmits a signal from the key to the receiver module every time the key is used. If the signal isn't in line with the one that the car has stored, the immobilizer will disable and stop the vehicle from starting. However, if the key fob isn't working and you can't reprogram it the issue could be due to a defective chip.

The chip inside the key fob may need to be altered to make it work again. The best method to do this is by removing the key from its housing and then using a pin or needle to make contact with each of the retaining clips made of steel. If these clips are damaged or broken, you will need to replace them in order for the remote control to work. Make sure that any replacement batteries have the same size, voltage, and specifications as the original one.
