With a thumb nail, or a small screwdriver with a flat-headed head (A) lift upwards the key fob battery compartment cover (B). Replace the coin battery CR2025, making sure it is placed in the correct direction and in the right polarity.

Dead Coin Battery

A dead battery for a coin is the most typical cause of a key fob not locking or unlocking your car. When it is dead you will see an increase in range, or no power. It is simple to replace it with a fresh one (CR2025) from an area supermarket. Be aware that faulty or unsuitable batteries may damage the seat key fob fob. Make sure that the battery you choose to replace is the same size and voltage, and also the same specification.

If your device has been exposed to clean water, for example rainwater or soapy water from the tap, it is likely that corrosion has caused damage to the chip's electronic circuit. You can try cleaning the chip with alcohol or an electronic cleaner to test if it helps, but it is likely that the chip has fried.

A new key fob is a simple solution. They are available at most major dealerships and can be installed by a qualified mechanic. You can also buy them online, such as on eBay. It is recommended to work on a surface that has good lighting. This makes it easier to work on the tiny parts inside. It also allows you to avoid putting something in the wrong place. Always work on your key fob in a place that is safe and secure.

Water Damage

If your key fob gets submerged after dropping it into the pool or throwing it in the wash, you may think it's over, but there's still hope. The problem starts when the circuit board in the fob comes into contact with water. It creates an excellent conductor and shorts components. It also accelerates corrosion and rust.

This is an easy fix. Find something absorbent, and put it inside the fob. A paper towl or tissue is ideal. Then, use a cotton swab that has been soaked in isopropyl alcohol and wipe down the circuit board as well as other components to eliminate any residue of battery acid and contamination. Let the fob dry out for some time in a dry and warm environment.

When the fob has been drained and the battery is replaced with a new one of the same size and polarity ('+' directed upwards). It can be tricky to open the fob to access the battery, but if you have a small screwdriver with a flat head handy it should slide in easily. Once the fob has been reassembled it should function like a normal. If it isn't working it may be necessary to re-program it or replace the module.

Radio Interference

If a key fob is functioning correctly, it transmits a radio frequency signal that is picked up by the receiver module inside your car. If the signal is interrupted, your key fob will not function. This could be due weather conditions, objects or other transmitters operating in the same frequency range close to your car.

This can cause your key fob to not activate the vehicle's functions like the ignition switch or the security system. In this scenario it's best to replace the battery in your key fob.

Some LED lighting from the aftermarket that utilizes the same frequency as a remote key fob could interfere with the signal and block it from reaching the receiver modules. The LED's lighting needs to be switched off or changed to a different frequency in order to keep out interference.

If the issue continues to persist after replacing the battery, the antenna of the key fob might be damaged or not functioning properly. This is important since the antenna is responsible for transmitting an indication 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 for information about your specific vehicle, such as the make and model along with the engine type and VIN number.

Faulty Receiver Module

The key fob has an encoder module that transmits the signals for lock and unlock. If the receiver module develops a fault that causes it to fail, the entire onboard electronics will stop working. Reprogramming the keyfob using an OBDII scan or replacing it may help.

There are a variety of possible causes for this issue that could be the cause, such as the battery of the coin is dead, water damage or signal interference. You can try resetting the computer on board by disconnecting the 12 volt battery for 15 minutes. This will remove any remaining electrical energy that could be causing problems. Begin by removing the cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, connect the battery in reverse order first: positive, then negative second.

Dirt and water can cause damage to the internal chip of the key fob. If the key fob you purchased stopped working after being wet, wash it with isopropyl or electronics cleaner. Then, reinstall the battery. If the key stops working after exposure to soapy or salted water, it is likely that the chip has become fried and needs to be replaced.

Another possibility is a faulty antenna module fuse, which transmits the lock or unlock signal to the vehicle. Depending on the model the fuse could be located in one of several locations including the engine bay, side of the dashboard, beneath the rear seat key replacement, or in the trunk.
