Dead Coin Battery

The most common reason for a key fob to not allow you to lock or unlock your car is a dead coin battery. If it fails, you will see the decrease in range or no power. It is easy to replace with a new one (CR2025) from the local supermarket. You should be aware that using the wrong or non-compatible batteries could damage your key fob. Make sure that the battery you purchase is the same size, specification and voltage as your old one.

If your device was exposed to clean water like rain or soapy tap water it is likely that the chip inside has been damaged due to corrosion. You could clean the chip with isopropyl or electronic cleaners to see if this helps, but it's likely that the chip has been damaged.

The simplest solution is to buy an entirely new key fob. Most major car dealers offer them and they can be installed by a seasoned mechanic. They can also be bought on the internet from sites like ebay. The best method is to work on a flat surface that has good lighting. It makes it easier to work with the smaller parts. This also helps you to avoid placing anything back in the wrong spot. Always work on the key fob in a secure and safe space.

Water Damage

It's possible to think that your fob is ruined if you drop it in a pool or accidentally wash it. But there's a way to salvage it. The problem is when the circuit board in the fob comes in contact with water - it creates a fantastic conductor and cuts off components. It also speeds up corrosion and rust.

This is a simple fix. Find something absorbent to place inside the fob. A paper towel or tissue will work. Use a cotton swab that contains isopropyl for cleaning the circuit board and any other components. Let the fob air dry in a warm, dry environment for several weeks.

Once the fob is been drained it is time to replace the battery another one of the same size and the same polarity ('+' directed upwards). It can be tricky to open the fob to access the battery but if you have a small flat-head screwdriver that you have at hand, it will be able to insert easily. After the fob is put back together, it should work like a normal. If it does not work, you may have to program it again or replace the module.

Radio Interference

If a keyfob works correctly, it emits a radio signal that is absorbed by a receiver module inside your vehicle. If the signal is distorted in some way, your key fob won't work properly. G28 Car Keys could be due to objects, weather conditions, or other transmitters that operate at the same frequency close to your vehicle.

In this instance it is recommended to replace the battery on your key fob. In this situation it is best to replace the battery inside your key fob.

A few LED lighting products that utilizes the same frequency as a key fob for remote control could interfere with the signal, preventing it from reaching receiver modules. The LED light must be switched off or changed to a different frequency in order to prevent interference.

If the issue is still present after installing a new battery, the antenna on your key fob may be damaged or not functioning properly. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will ask you for details about your vehicle, including the model, make engine type, VIN number.

Faulty Receiver Module

The key fob features an electronic receiver that transmits signals for locking and unlocking. If the receiver module develops a fault that causes it to fail, the entire onboard electronics will cease to function. Reprogramming the key fob by an OBDII scan, or replacing it may help.

This issue can be caused by a dead coin-cell or water damage, or signal interference. You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 mins. This will eliminate any remaining electrical energy that could cause issues. Start by removing the cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.

The presence of dirt or water could affect the internal chip inside the key fob. If your key fob stopped working after getting wet, clean it using isopropyl or an electronic cleaner. After that, replace the battery. If the key ceases to function after exposure to salted or soapy water, it's likely that the chip is damaged and needs to be replaced.

A defective fuse for the antenna module 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 several locations including the engine bay, to the left of the dashboard, beneath the rear seat, or in the trunk.
