Dead Coin Battery

The most frequent reason for a key fob to not lock or unlock your car seat key is due to a dead coin battery.

Water Damage

If your fob's key gets submerged after dropping it into the pool or by slipping it in the wash you might think that it's lost but there's a chance. If the circuit board inside the fob is exposed to water, it transforms into a conductor that shorts out the components. It also speeds up the process of rust and corrosion.

This is an easy solution. Find something absorbent to put inside the fob. A tissue or paper towel would be a good choice. Then, use an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to clean the circuit board and other components to get rid of any residues of acid from batteries and contamination. Let the fob air dry in a warm, dry environment for several weeks.

Replace the battery once the fob has dried out by replacing it with a new one that has the same size and polarity ('+' (pointing upwards). It is a challenge to open up the fob to get access to the battery but if you have a small flat-head screwdriver handy it should slide in easily.

Radio Interference

The antenna is responsible for transmitting signals between the key fob and the receiver module. An OBDII scan will aid in diagnosing the issue by revealing what's wrong with your system. The scanner will ask for information about your vehicle including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

This problem could be caused by a dead coin-cell or water damage, or signal interference. It is possible to reset the on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will draw out any remaining electrical energy that could cause issues. Start by removing the cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, reconnect your battery in reverse order. First, positive, then negative, and finally negative.

Dirt or water can cause damage to the internal chip of the key fob. If your key stopped working when it was wet, wipe the electronic component with isopropyl ethanol or an electronic cleaner prior to installing the battery. If it stops working after exposure to salty or soapy water the chip could be damaged and needs to be replaced.

A defective fuse for the antenna module could also be the reason. It's the fuse that sends a signal to the vehicle to lock or unlock. The fuse can be found in a variety of locations, based on the type of vehicle. For example it could be located under the rear seat leon spare key, or in the trunk, or the side of the dashboard.
