If the key fob still doesn't function, it might be time to invest in an entirely new one.
Another common reason that can be the reason behind Citroen c3 remote control not working is signal interference. This can occur when there is an intense electrical field that is close to the vehicle or from other transmitters on the same frequency. g28carkeys.co.uk should begin working once you are out of the area of interference.
The Citroen C3 key fob might stop working because of worn buttons or signal interference issues, receiver module issues, a dead 12-volt battery or a damaged chip. If this happens, you'll likely need to get it changed by a certified expert. This can be accomplished by a certified mechanic or a Citroen dealer.

Receiver module issue
If your key fob ceases working, it might be because the receiver module has developed an issue. This can be caused by several things that include water damage. This can happen if lose your keys, or wash them. You can try to fix the problem by taking off the chip and cleaning it with isopropyl or electronic cleaner. This will prevent the chip from becoming corroded.

Interference can cause your key to stop working. It could be caused by other transmitters that utilize the same frequency as your key fob, or even objects in your vehicle. If you're unable to fix the issue, take your key fob to a dealer and have it reset.
The key fob contains a short-range radio transmitter/radio-frequency identification (RFID) chip and antenna, which sends a distinct coded signal to the receiver module in your car. If the signal is not accurate, the receiver will not recognize the car key and display a message stating "key not recognized". This could be a very frustrating issue, especially when trying to start your car.
Dead 12 volt battery
It is possible that your key fob is damaged if it stops working after changing batteries.

If this happens, you can reset all on-board computers by disconnecting the battery with 12 volts for approximately 15 minutes. This will remove any residual electric current, allowing your system to reboot.
Before replacing the battery, it is essential to ensure it's the correct type and size. If the battery you replace isn't big enough or has a different voltage, it can damage the circuit board within the fob's key.
