Batteries for fobs are typically CR2025 or CR2032 However you must consult the owner's manual for your vehicle to determine which kind is required.

Take off the button pad and then use cotton swabs or alcohol to clean it. These will help remove corrosion and clean the contacts which are typically colored gold. Once the contacts are cleaned, you can insert the new battery. Be careful not to mix the two types since they have different voltages, sizes and diameters.

The next step is to assess the voltage of the battery. A multimeter that is set to the battery's voltage range will give you an accurate reading. If the battery is at a value above or below its threshold, it needs to be replaced. You could also try the car's start using a spare key, but this may not be successful in all instances.

Water damage

If the key fob is submerged, it may lose its signal. It's best to remove it as quickly as you can from the pool or puddle. Once you do, dry out the circuit board as best you can using an abrasive swab of cotton that's been soaked in isopropyl ethanol or electronic cleaner. If it doesn't work, it may be time to get a new key fob.

Another reason that is commonly cited 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 close to the car, or from other transmitters operating on the same frequency.

Issue with the Receiver module

If your key fob ceases functioning, it could be because the receiver module has developed an issue. Water damage is one of the numerous causes. This could happen if you drop your keys or wash them. You can solve the problem by removing your chip and cleaning it with isopropyl, or electronic cleaner. This will keep the chip from corroding.

Before replacing the battery it is essential to ensure that it's the right size and type. The circuit board inside the fob's circuit board could be damaged in the event that the replacement battery is too big or has different voltage. Before installing a battery you should clean the chip of the fob to eliminate any corrosive substances. The right battery type can ensure that the key fob is sealed and protected from moisture.
