After the contacts have been cleaned then you can put in the new battery. Just be careful not to mix the two kinds because they have different voltages and sizes.
The next step is to check the battery's voltage. A multimeter that is set to the battery's voltage range will give you a reliable reading.

Water damage
If the key fob is submerged it can lose its signal. It's best to remove it as fast as possible out of the pool or puddle. After that make use of the cotton swab along with isopropyl or electronic cleaner to dry the circuit board. If the key fob isn't working, it could be time to buy an additional one.
Another reason that can be cited one of the main reasons for Citroen c3 remote control not working is signal interference. It can happen when there is an intense electrical field close to the vehicle, or from other transmitters operating on the same frequency. Once you leave the interference area your key fob should be working normally again.
Lastly, the Citroen C3 key fob may not function due to worn buttons or signal interference, receiver module issues, a dead 12 volt battery, or a damaged electronic chip. It will need to be reprogrammed if this happens. This can be accomplished by a qualified mechanic or at a Citroen dealership.

Receiver Module Issue
If your key fob stops functioning, it could be due to the receiver module having developed an issue. Water damage is one of the numerous reasons. This could happen if you lose your keys or wash them. You can try to fix the problem by taking off the chip and cleaning it with isopropyl or an electronic cleaner. This will prevent the chip from becoming corroded.
You could also try to reset the receiver module by disconnecting it from the car battery and waiting for 10 seconds. You can then reconnect the battery and repeat the process. If this does not resolve the issue, you can take it to a retailer to be replaced.
Another reason why your key could not work is due to interference. It can be caused by other transmitters using the same frequency or objects in your vehicle. If you are unable fix the issue, you can bring your key fob to an authorized dealer and have it reprogrammed.

If the signal doesn't match the receiver module will not recognize the key and will display a message that says "Key Not Detected. This can be a gruelling issue, particularly when trying to start your vehicle.
Dead 12 volt battery
It is possible that your key fob may have been damaged if it ceases to function after a change in batteries.

A remote that receives interference from other devices and locations is another possibility. This could make RF signals weaker and block the car from recognizing the remote. If this happens you can reset the computer systems on board by disconnecting the 12 volt battery for approximately 15 minutes. This will remove any residual power, allowing the system to restart.
It is essential to verify the size and type of the battery prior to replacing it. The circuit board that is inside the fob's circuit board could be damaged if the replacement battery is too large or has an incompatible voltage. It is also recommended to clean any corrosive material from the chip inside the fob before installing a new battery. The proper type of battery will ensure that the key fob is properly sealed and shielded from moisture. Once the key fob is reinstalled, it should work normally.
