The chip can be permanently damaged by water. If the key fob does not work after replacing the battery, it might be necessary to replace the key fob.

Faulty Receiver Module

If your key fob stopped working after replacing the battery and it did not help, or it just stopped working suddenly, then your receiver module may have developed an issue. The receiver module receives radio frequency signals from the remote keyfob and transforms them into electrical signals which are then acted upon by other modules inside the car.

Then reconnect the battery in reverse order (negative cable first before positive). This will reset the onboard electronic and restore their functionality.

A malfunctioning electronic chip

The key fob is outfitted with a tiny chip that transmits an indication from the key to the receiver module each time the key is used. If the signal doesn't match the one recorded by the car the immobilizer will shut down the engine and stop the vehicle from starting. If the key fob doesn't work and you aren't able to reprogram it, this could be because of an issue with the microchip.


The chip inside the key fob is not a permanent part of the device, and might need to be replaced to get it to work again. This can be accomplished by removing the key fob from its case, and using pins or needles to contact each metal retaining clip. If these are corroded or damaged, you'll need to replace them in order for the remote control to work. Make sure that any replacement batteries have the same size, voltage, and specification as the original.
