If your C3 key fob suddenly stopped working, it could be because of an issue with the module. If the key fob's function is functional, the issue could be due to something else, such as water damage or a dead battery for the coin.

The eC3 is aimed at the mass market, and Citroen has worked to make service simple for customers. It offers several facilities such as remote diagnostics through virtual computers and a specialized customer service app.

Dead coin battery

If the unlock button on the key fob isn't working, or if the unlock button does not work, it may be that the battery for the coin is faulty. The battery should last between three and four years if used regularly but it can fail suddenly. Fortunately, automakers have built-in fail-safes so that you are able to unlock and start your car even if the key fob is dead battery.

The battery inside the key fob is secured with metal clips that complete the circuit. The battery may not be powered if these clips are dirty or worn. The battery should also be of the correct size and type. The battery won't fit in the fob if it's too large or too small.

Key fob batteries are sold under various names including CR2016 and CR2032. They are not interchangeable. The best way to determine which type to purchase is to refer to your owner's manual, or look over the fob for an inscription that gives you the specific details.

When you've got the proper battery that you want to replace, it can be done in just a few moments. Most fobs have a slider, switch, or gap that you can use to pry open the cover and swap the old one for an alternative. Be sure that the new battery has the same voltage as the old one and is inserted correctly.

Water damage

Water is harmful to electronics, even if they have been through an wash cycle or dip. It can damage the chip and destroy a battery. Fortunately, there are a few things you can do to limit the damage.

It's important to first remove the battery first, and then dry out the interior as possible. You can also clean the battery using a cotton swab that has been dipped in 90 percent alcohol.

After cleaning the key fob you should let it dry for several days. You can speed it up by placing it on a shelf to ensure it will not be disturbed. Once you are sure that the battery is totally dry, replace it with an additional battery and continue using it as usual.

If the key fob still does not work, you might have a malfunctioning receiver module that's not able to send signals to your vehicle. This can be quite expensive to repair, but it's well worth trying if you want to avoid a costly replacement.

The simplest way to fix an faulty key fob, is to replace the battery. The radio signal should be restored and your key fob should work again after changing the battery. If the issue persists, you should seek assistance from a professional.

Faulty receiver module

In some cases, the key fob's receiver module may have a defect that is preventing it from receiving or transmitting the proper signal. In this case the car will not recognize the remote control key. It won't unlock or start. In this situation you'll need another replacement.

Consult your owner's guide before attempting to reprogram the key fob on your own. Ensure that the battery of the key fob is in good health and that all buttons work. Also, close the doors and disconnect any other aftermarket devices, such as radios or alarm systems from the vehicle.

You may also try cleaning the chip with isopropyl Alcohol or electronic cleaner. If the chip is damaged, it will probably need to be replaced.

After cleaning the key fob, remove the circuit board. Then, use alcohol swabs to clean the contacts and let them air dry. Once the contacts have dried then you can reassemble and test the key fob. If the key fob doesn't work, then it might be necessary to replace the battery. Use a battery that has the same voltage as the battery you replaced. It's recommended to ensure that the battery is installed correctly in the first place, since the contact points can be extremely sensitive.

Keyless entry systems that aren't working properly

The key fob is an excellent convenience in vehicles but it can also be a hassle when it stops working. The good news is that most times it's simple to get it working again. A dead coin battery is the most frequent reason for a fob that is malfunctioning. It can be replaced in a matter of minutes. Other causes include signal interferance, a bad module and other electrical issues.

The first step is to make sure that the battery is of the correct voltage and is properly inserted. It is also essential to select the correct battery type. Using an incorrectly sized or polarized battery can damage the internal circuitry. Examine the fuses for damage or burned.

Another possibility is that the transponder within the key may have been damaged or destroyed. This issue will require an examination by a professional mechanic or dealer in cars.

Many dealerships and auto locksmiths can reprogram the car's key fob for a small fee, but this can be costly. If you have an extra, it could be worth trying to reprogram the fob yourself. The instructions are usually found in the owner's manual. If you don't own the manual, you can find instructions online or on YouTube. Before you attempt to fix the key fob, it is important that you consult the owner's guide.
