Water Damage

It's possible to think that your fob is damaged if you drop it in the pool or accidentally wash it. However, there's still a chance. If the circuit board inside the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also accelerates corrosion and rust.

Fortunately, this is easy to fix. Find something absorbent to put inside the fob. A paper towel or tissue will be a good choice. Make use of a cotton swab and isopropyl to wash the circuit board, and any other components. Allow the board to dry for several days in a dry and warm environment.

When the fob has dried out, replace the battery with a new one of the same size and the same polarity ('+' that is pointing upwards). It can be difficult to open the fob to access the battery but if you have a small screwdriver that is flat at hand, it will slide in easily. After the fob has been reassembled, it should work as normal. If it fails, you may have to program it again or replace the module.

Radio Interference

If a keyfob works properly, it transmits an audio frequency that is received by a receiver module in your car. If the signal is interrupted in any way the key fob will not work properly. This could be due factors like weather conditions, objects, or other transmitters operating on the same frequency band close to your car.

This could cause your key fob to not be able to activate the vehicle's features such as the ignition switch or the security system. In this scenario it is recommended to replace the battery on your key fob.

A few aftermarket LED lighting fixtures that uses the same frequency as a remote key fob could interfere with the signal and block it from reaching the receiver modules. To avoid interference, the LED lights must be switched off or to another frequency.

If you've just replaced the battery on your key fob but the problem persists, it's possible that the antenna on your key fob is damaged or has stopped working. The antenna is responsible to transmit a signal between the key fob and the receiver module. Using an OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will ask you to provide information about your vehicle including the model, make engine type, VIN number.

Faulty Receiver Module

The key fob features an electronic receiver that transmits signals to lock and unlock the key fob. If the receiver module develops a fault, all of the on-board electronics will stop working. If this happens it is possible to reprogramme the module using an OBDII scanner or replacing the key fob could help.

This issue could be caused by a dead battery in the coin-cell or water damage, or signal interference. You can try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will eliminate any remaining electricity that may be causing problems. The cable should be removed first from the negative terminal, then from the positive terminal. After 15 minutes, connect your battery in reverse order. First positive, then negative, and finally negative.

Water or dirt can also harm the internal chip of the key fob. If www.g28carkeys.co.uk stopped when it was wet, you need to clean the electronic component with isopropyl Alcohol or an electronic cleaner prior to installing the battery. If the key ceases to function after exposure to soapy or salted water, it's likely that the chip has been fried and needs to be replaced.

A defective antenna module fuse may also be the cause. It is the fuse that sends an electronic signal to the vehicle to lock or unlock. Depending on the model the fuse could be located in one of the many locations such as the engine bay, to the left of the dashboard, beneath the rear seat, or trunk.
