Dead Coin Battery

A dead coin battery is the most common cause of a key fob not locking or unlocking your car. It usually displays warning signs prior to dying such as a decreased range or no power at all. It is easy to replace with a brand new one (CR2025) from the local supermarket. You should be aware that using the wrong or non-compatible batteries can damage your key fob. Make sure that the battery you purchase is the same size, specification and voltage as the old one.

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

The best way to work is to work on a flat, level surface with adequate lighting. This makes it easier to work on the tiny parts inside. This can also help to avoid putting something back in the wrong spot. Always work on the key fob in a secure and safe area.

Water Damage

If your key fob gets wet from dropping it into the pool or throwing it in the washing machine, you may think that it's gone but there's still hope. The problem begins when the circuit board within the fob comes into contact with water. It creates a fantastic conductor and shorts out components. It also speeds up corrosion and rust.

Luckily, this is a simple issue to fix. Find something absorbent, and place it inside the fob. A paper towl or tissue can be used. Use a cotton swab that contains isopropyl to cleanse the circuit board, and any other components. Let the circuit board dry for several days in a dry and warm environment.

Replace the battery after the fob has dried with a new one that is the same size and polarity ('+' (pointing upwards). It isn't easy to open up the fob to access the battery, however if you have a small screwdriver that is flat available, it should be able to slide into easily. Once the fob is reassembled, it should work as normal. If it doesn't, then you'll require reprogramming it or replace the receiver module.

Radio Interference

When a key fob working correctly, it sends the radio frequency signal which is interpreted by the receiver module in your car. If the signal is disrupted the key fob won't function. This could be due weather conditions, objects or other transmitters operating in the same frequency range near your vehicle.

This can cause your key fob's button to not work the vehicle's features, such as the ignition switch, or the security system. In this scenario it is best to replace the battery inside your key fob.

A few aftermarket LED lighting fixtures that utilizes the same frequency as a remote key fob can interfere with the signal and stop it from reaching the receiver modules. The LED lighting must be switched off or changed to a different frequency in order to prevent interference.

If you've got a new battery on your key fob but the issue persists, it is likely that the antenna on your key fob is damaged or not functioning properly. This is important since the antenna is responsible for sending signals from the key fob to the receiver module. The OBDII scanner is able to aid in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you for details about your particular vehicle including the make and model of the vehicle, the type of engine, and VIN number.

seat key cover  has an electronic receiver that sends the signals for locking and unlock. All on-board electronic components will stop working if the receiver module develops a problem. If this is the case, reprogramming with an OBDII scanner or replacing the key fob itself may assist.

This problem could be caused by a dead coin-cell or water damage, or signal interference. You can reset your on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will remove any remaining electrical energy that could be causing issues. Begin by removing your cable from the negative terminal first, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First, positive, then negative second.

The internal chip of the key fob can also be damaged by dirt or water. If your key fob stopped functioning after being wet, wash it with isopropyl or electronics cleaner. Then reinstall the battery. If it stopped working after exposure to salty or soapy water the chip may be damaged and needs to be replaced.

A defective antenna module fuse could also be the reason. This is the fuse that transmits an alert to the vehicle to lock or unlock. Based on the model you have the fuse can be located in a variety of locations including the engine bay, to the left of the dashboard, under the rear seat, or in the trunk.
