After the contacts have been cleaned, you are able to put in the new battery. Be careful not to mix the two types as they have different voltages, dimensions and shapes.

The next step is to check the battery's voltage. A multimeter calibrated to the battery's voltage range will provide you with a precise reading. If the battery has an amount that is above or below its threshold, it has to be replaced. Try the car's start using a spare key, but it may not work in all situations.

Another common cause one of the main reasons for Citroen c3 remote control not working is signal interference. This could happen when there is an intense electrical field in the vicinity of the vehicle or from other transmitters operating on the same frequency. The key fob should start working again after you are out of the zone of interference.

It can happen when you lose your keys, or wash them. You can try to repair the issue by removing the chip and cleaning it with isopropyl or electronic cleaner. This will keep the chip from becoming corroded.

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

Before replacing the battery, it's important to make sure it's the correct size and type. If the replacement battery isn't big enough or has an incompatible voltage, it could damage the circuit board inside the fob's key.
