Use a small screwdriver or a thumbnail (A) to open the battery compartment cover of the key fob (B). Replace the coin battery CR2025 to ensure that it's in the correct direction and in the right polarity.

Dead Coin Battery

A dead battery on a coin is the most common reason of a key fob not locking or unlocking your car. It will usually show indications before it dies, such as a decreased range or no power at all. It is simple to replace it with a brand new (CR2025) one at your local grocery store. Be aware that using the wrong or unsuitable batteries could damage your key fob. Make sure the replacement battery is the same size and voltage, and also the same specification.

If your fob was exposed to clean water like rain or soapy tap water, it is possible that the electronic chip inside has been damaged due to corrosion. You may try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is most likely that the chip has been fried.

The simplest option is to buy a new key fob. They can be purchased from a variety of major car dealers and are installed by a qualified mechanic. They can also be bought on the internet from sites like ebay. It is best to work on a surface with good lighting. It is much easier to work on the small parts. This can also help to avoid placing anything back into the wrong place. Always keep your key fob in a place that is safe and secure.

Water Damage

You might think that your key fob is destroyed if drop it in the pool or accidentally wash it. But there's still hope. When the circuit board in the fob is exposed to water, it becomes a conductor that shorts out the components. It also accelerates the process of rust and corrosion.

Fortunately, this is not difficult to fix. Find something absorbent, and place it inside the fob. Paper towl or tissue is ideal. Then make use of a cotton swab that has been soaked in isopropyl ethanol to wipe down the circuit board and other components to remove any battery acid residue or contamination. Allow the circuit board to air dry in a warm, dry environment for a few weeks.

When the fob has been drained then replace the battery with a new one of the same size and polarity ('+' that is pointing upwards). It can be difficult to open the fob to get access to the battery but if you have a small flat-head screwdriver handy it should slide in easily. Once the fob has been rebuilt, it should operate as normal. If it does not work then you might need to program it again or replace the module.

Radio Interference

If a key-fob is functioning correctly, it transmits a radio frequency signal that is picked up by the receiver module in your car. If the signal is disrupted the key fob won't work. This could be due to objects such as weather conditions, objects, or other transmitters that operate at the same frequency as your vehicle.

This can cause your key fob not to be able to trigger the vehicle's systems like the ignition switch or security system. In this scenario it's best to replace the battery on your key fob.

Some LED lighting accessories that utilizes the same frequencies as the remote control key fob can interfere with the signal, stopping it from reaching receiver modules. The LED's light source must be turned off or switched to a different frequency to keep out interference.

If you've just replaced the battery in your key fob, and the issue persists, it's likely that the antenna on your key fob is damaged or has stopped working. The antenna is responsible for transmitting a signal between the key fob and the receiver module. Using an OBDII scanner can aid in identifying the issue by telling you what is wrong with the system. The scanner will ask you for information about your vehicle including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob houses an electronic receiver that sends the signals needed to lock and unlock. All electronic components that are on-board will stop working if the receiver module has a problem. Reprogramming the key fob by an OBDII scan, or replacing it can help.

This problem can be caused by a dead coin-cell battery, water damage or signal interference. You can reset the onboard computer by disconnecting the 12 Volt batteries for 15 mins. This will drain any residual electrical energy that could be causing issues. Begin by removing the cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

Dirt and water can damage the internal chip of the key fob. If your key fob stopped functioning after getting wet, clean it with isopropyl or electronics cleaner. Then, reinstall the battery. If it has stopped working after exposure to soapy or salty water the chip could be damaged and should be replaced.

Another possibility is a damaged antenna module fuse that is sending the lock / unlock signal to the vehicle. Depending on your model the fuse could be located in a variety of locations like the engine bay, the side of the dashboard, beneath the rear seat leon key fob replacement, or trunk.
