If your C3 key fob suddenly stopped functioning it could be because of an issue with the module. If the key fob's function is operational, the issue could be caused by something else, like water damage or a dead coin battery.

Citroen aims to serve the mass market with its eC3. It comes with a variety of options, including virtual remote diagnostics and a dedicated customer support application.

Dead coin battery

If the key fob's unlock button doesn't functioning, there could be an issue with the coin battery. The battery's lifespan should be between three and four year with regular usage. However, it could abruptly die. The car manufacturers have designed fail-safes that allow you to lock and start the vehicle even if your key fob is dead.

The battery inside the key fob is secured with metal clips that complete an electrical circuit. If the clips are worn or filthy, the battery might not be able to receive electricity. The battery should also be of the correct size and type. If the battery is too small or too large, it will not fit in the fob and will not function properly.

Key fob batteries are typically sold under different names, including CR2016 and CR2032 (though they aren't interchangeable). The best way to determine the type to buy is to refer to your owner's manual, or look over the fob for the label that contains the specific information.

When you have the proper battery, you can swap it in a few minutes. Most fobs have a slider, a switch, or a gap that can be used to pry the cover open to replace the old battery. Make sure that the new battery has the same voltage and that it is placed in the correct way.

Water damage

Even if your key fob survived the wash cycle or an immersion in the pool, water isn't ideal for electronics. It can damage the chip and damage the battery. There are, however, some things you can do to limit the damage.

It is important to first take out the battery first, and then dry the inside as possible. You can also clean the battery using a cotton-swab that has been submerged in 90 percent alcohol.

After cleaning the key fob you should let it dry for a few days. You can accelerate the process by placing it on a high shelf that isn't disturbed. Once you're sure that it's bone dry try replacing the battery and operating it as usual.

If the key fob still does not work, you might have a problem with the receiver module that's not transmitting signals to your vehicle. This could be expensive to repair, but it's worth trying to avoid a costly replacement.

The easiest method to fix a malfunctioning key fob is to replace the battery. Changing the battery should restore the radio signal and make your key fob work once more. If the problem persists you should seek professional assistance.

The receiver module is not working properly.

In some instances the key fob's receiver module could be defective that hinders it from receiving and transmitting the proper signal. If this is the situation, your car will not recognize your remote control key and will refuse to unlock or start the engine. In this scenario an alternative remote control will be needed.

Consult your owner's guide before attempting to reprogram the key fob on your own. The first step is to ensure that the battery of the key fob is in good health and that all buttons are functioning. It is also recommended to shut the doors and disconnect any accessories like radios or alarm systems from the vehicle.

You might also try cleaning your chip using isopropyl alcohol, or an electronic cleaner. If the chip is in a state of disintegration it is likely to be replaced.

After cleaning the key fobs, remove the circuit board. Then, clean the contacts with alcohol swabs. Let them dry. After the contacts have dried then you can reassemble the key fob and test it. If it's still not working, you may need to replace the battery. Choose a new battery that has the same voltage as the battery you replaced. Check the battery's location, since the contact points are extremely sensitive.

Keyless entry system that isn't working properly

It can be a hassle If the key fob ceases working. It's not difficult to get your key fob back working. A dead battery for the coin is the most common cause of a malfunctioning fob. It can be replaced in a matter of minutes. Other causes are signal interference, an ineffective receiver module or other electrical issues.

The first step is to ensure that the battery is properly placed and has the proper voltage. It is also essential to select the correct battery type. If you use a wrongly sized or polarized one could cause damage to the internal circuitry. You can also check the fuses to ensure they're not blown or have not been melted.

Another possible problem is that the transponder within the key could have been damaged or lost. This is a problem that requires further testing by a car dealer or professional mechanic.

Auto locksmiths and dealerships can reprogram the fob of your car's keys at a cost, but it can be costly. If you have an extra key, it may be worth trying to reprogram the fob yourself. In the majority of cases, you will get instructions from the owner's manual. If you don't have a manual, you can find instructions online or on YouTube. It is imperative to check the owner's manual prior to making any repairs to the key fob.
