Dead Coin Battery

A dead battery on a coin is the most common cause of a key fob not locking or unlocking your car. Before it dies you'll see an increase in range, or no power. It is simple to replace it with a new (CR2025) one from your local store. You should be aware that using the wrong or unsuitable batteries could cause damage to your key fob. Make sure that the battery you choose to replace is the same size and voltage as well as the same specification.

If your device was exposed to clean water such as rain or soapy tap water, it is possible that the electronic chip inside has been damaged due to corrosion. You can clean the chip with isopropyl or electronic cleaners to determine if that helps, but that the chip is fried.

A new key fob is a simple solution. They can be purchased from a variety of major car dealers and can be fitted by a professional mechanic. You can also buy them on the internet, for instance on eBay. The best method is to work on a level surface with excellent lighting. This makes it easier to work on small parts inside. You will also be able to avoid placing something in the wrong place. Always keep the key fob in a secured and safe place.

Water Damage

You may think your key fob is ruined if you drop it in an unintentional pool or accidentally wash it. However, there's still a chance. The problem starts when the circuit board within the fob comes in contact with water - it is a great conductor and cuts off components. It also accelerates corrosion and rust.

This is an easy fix. Simply locate something absorbent and place it inside the fob. Paper towl or tissue is ideal. Then, use the cotton swab, dipped in isopropyl alcohol 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 dry, warm environment for a few weeks.

Replace the battery once the fob has dried out by a new one that has the same size and polarity ('+' (pointing upwards). It can be tricky to open the fob to get access to the battery but if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily. Once the fob has been reassembled it should function like a normal. If it doesn't, you may need to reprogramme it or replace the receiver module.

Radio Interference

If a key fob is functioning properly, it sends a radio ry in reverse order. Positive first, then negative second.

Water or dirt can also harm the internal chip of the key fob. If your seat spare key stopped working after being wet, clean the electronic component with isopropyl ethanol or an electronics cleaner before installing the battery. If the key ceases to function after being exposed to salted or soapy water, it is likely that the chip has been damaged and must be replaced.

A defective fuse for the antenna module could also be the reason. It is the fuse that transmits a signal to the vehicle to lock or unlock. The fuse could be found in various places, based on the model. For example it could be under the rear seat arona key cover or trunk, or on the side of the dashboard.
