Once the contacts are cleaned, you can insert the new battery. Be careful not to mix the two batteries as they have different voltages, dimensions, and shapes.
The next step is to determine the voltage of the battery. You can get an accurate reading with a multimeter that is calibrated to the battery's voltage range. If the battery is at the value that is either above or below its threshold, it needs to be replaced.

Once you've done that, use a cotton swab, isopropyl or electronic cleaner to clean the circuit board. If the key fob still isn't working, it may be time to get an additional one.
Another reason that is commonly cited for
citroen ds3 remote key replacement remote control c3 not working is signal interference. This could happen if there is an electrical field near the vehicle or other transmitters that operate on the same frequency. Once you have left the interference area your key fob should be working normally again.

Receiver module issue
If your key fob isn't working it could be because the receiver module might have developed an issue. Water damage is among the numerous reasons. This can occur when you drop your keys or wash them. You can try to repair the issue by removing the chip and cleaning it with isopropyl or an electronic cleaner. This will help to keep the chip from getting damaged.
You can also reset the receiver module when you disconnect it from the battery and then wait 10 seconds. Then reconnect the battery to the car and repeat the procedure. If this does not fix the issue, you can bring it to a dealer for replacement.

A remote that receives interference from other devices and locations is a different possibility. This could cause the RF signals to weaken and block the car from being able to recognize the remote. You can reset your on-board computer in this situation, by disconnecting the 12-volt battery for 15 minutes. This will erase any remaining electrical energy, allowing the system to restart.
Before replacing the battery, it's important to make sure it's the correct size and type. The circuit board on the key fob can be damaged if the replacement battery is too big or has a different voltage. Before you install a battery you should clean the chip inside the fob in order to eliminate any harmful substances. Using the correct type of battery can help ensure that it is sealed and shielded from moisture. Once the key fob's been installed, it should work normally. In the majority of cases, you can use the second key to start your vehicle even when it displays the message "key is not detected." It might be necessary to press the button several times before it responds.
