If the key fob does not work, it may be time to buy an entirely new one.

Signal interference is a different reason for citroen ds3 key fob remote controls not working. It can happen when there is an electrical field close to the vehicle or other transmitters on the same frequency. The key fob should start working again after you have left the zone of interference.

This could happen if you drop your keys or wash them. It is possible to fix the issue by taking off and cleaning the chip using isopropyl alcohol or electronic cleaner. This will prevent corrosion of the chip.

You can also try to reset the receiver module by disconnecting it from the car battery, and waiting for 10 seconds. Then, reconnect the battery and repeat the process. If this isn't enough to fix the issue, you can take it to a dealership to be repaired.

This will take away any remaining power, allowing the system to restart.

It is essential to verify the size and quality of the battery prior to replacing it. If the battery you replace isn't big enough or has an incompatible voltage, it could damage the circuit board within the key fob. You should also remove any corrosive substances from the chip in the fob before installing a new battery.
