Dead Coin Battery

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

Be aware that defective or unsuitable batteries can damage the key fob. Make sure that the new battery has identical in size, specifications and voltage as the older one.

If your fob has been exposed to clean water, such as rainwater or soapy water from the tap, it is likely that corrosion has caused damage to the chip's electronic circuit. You can clean the chip with isopropyl or electronic cleaners to see if that aids, but that the chip is fried.

Water Damage

If your key fob gets submerged after dropping it into the pool or throwing it in the washing machine you might think it's a goner but there's hope. When the circuit board on the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also accelerates the process of rust and corrosion.

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

After the fob has been drained it is time to replace the battery another one of the same size and polarity ('+' with the upwards direction). It can be difficult to open the fob to get access to the battery, however if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily.

Radio Interference

When a key fob working correctly, it sends a radio frequency signal that is received by the receiver module in your car. If the signal is interrupted, your key fob won't work. This could be due to things, weather conditions or other transmitters operating within the same frequency band near your car.

A few LED lights that are aftermarket and utilizes the same frequency as a remote key fob might interfere with the signal and stop it from reaching the receiver modules. The LED's light source must be turned off or switched to a different frequency to keep out interference.

If the problem persists after replacing the battery, the antenna on the key fob might be damaged or inoperable. This is because the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scan will help you identify the issue by telling you exactly what's wrong with the system. The scanner will ask for details about your vehicle including the model, make engine type, and VIN number.

Faulty Receiver Module

The key fob comes with a receiver module which transmits signals for locking and unlocking. All electronic components on board will stop working if the receiver module is affected by a malfunction. If this happens then reprogramming the module using an OBDII scanner or replacing the key fob may help.

This issue can be caused by a dead battery in the coin-cell, water damage or signal interference. You can try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will flush out any residual electric current that could cause problems. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First, positive and then negative the next.

The presence of dirt or water could cause damage to the internal chip of the key fob. If your key has stopped working after it got wet, wash the electronic component with isopropyl alcohol or an electronics cleaner before reinstalling the battery. If it is not working after exposure to salty or soapy water the chip could be fried and will need to be replaced.

Another possibility is an inoperable antenna module fuse that sends the lock or unlock signal to the vehicle. The fuse may be located in several places, depending on the type of vehicle. For example it could be beneath the rear Seat Car Key Fob Battery Type, or in the trunk, or on the side of the dashboard.
