Using a thumb nail or small screwdriver that has a flat head (A) and pull upwards the key fob battery compartment cover (B). Replace the CR2025 battery, ensuring it is placed in the correct direction.

Dead Coin Battery

The most common reason for a key fob that does not be able to lock or unlock your car is a dead coin battery. When it is dead you'll see a decrease in range or no power. It is simple to replace it with a new (CR2025) one from your local store. Be aware that using the wrong or unsuitable batteries can cause damage to your key fob. Be sure that the replacement battery is the same size and voltage, as well as the same specification.

If your fob 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 may try cleaning the chip using isopropyl alcohol or an electronic cleaner to check if it works but it is most likely that the chip has fried.

The most efficient solution is to purchase a new key fob. They can be purchased from a variety of major dealerships and can be fitted by a professional mechanic. You can also purchase them on the internet, for instance on eBay. The best thing to do is to work on a level surface with adequate lighting. This makes it easier to work on small parts inside. It also allows you to avoid putting things in the wrong spot. Always work on the key fob in a secure and safe space.

Water Damage

If your key fob is soaked by dropping it in the pool or fumbling it in the washing machine, you may think that it's lost but there's hope. The problem starts when the circuit board in the fob is in contact with water. It is a great conductor and shorts components. It also accelerates corrosion and rust.

Fortunately, this is easy to fix. Simply find something absorbent and place it inside the fob. Paper towl or tissue works well. Use a cotton swab that contains isopropyl to wash the circuit board, and any other components. Allow the circuit board to air dry in a dry, warm environment for a few weeks.

When the fob has been drained then replace the battery with a new one (of the same size and the same polarity ('+' with the upwards direction). It isn't easy to open the fob in order to access the battery, however if you have a small flat-head screwdriver handy it should slide in easily. After the fob is put back together, it should work like a normal. If it doesn't, you might need to reprogramme it or replace the receiver module.

Radio Interference

If a key fob is functioning properly, it sends a radio frequency signal that is picked up by the receiver module in your car seat key. However, if the signal is disrupted in any way the key fob will not function as expected. This could be due to objects, weather conditions, or other transmitters operating on the same frequency near your car.

This can cause your key fob's button to not work the vehicle's features such as the ignition switch or security system. It is recommended to replace your key fob's battery.

Some LED lighting accessories which uses the same frequency as a remote control key fob may interfere with the signal, stopping it from reaching receiver modules. The LED's light source must be switched off or changed to a different frequency in order to keep out interference.

If you have a new battery in your key fob, and the issue persists, it's possible that the antenna on the key fob is damaged or malfunctioning. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scan can aid in diagnosing the issue by telling you exactly what's wrong with your system. The scanner will ask you for details about your vehicle, such as the model and make of the vehicle, the type of engine, and VIN number.

Faulty Receiver Module

The key fob comes with a receiver module that transmits signals to lock and unlock the key fob. If the receiver module fails then all the on-board electronics will stop working. Reprogramming the key fob with an OBDII scan or replacing it may help.

This issue can be caused by a dead coin-cell battery, water damage or signal interference. You can reset the on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will eliminate any remaining electrical energy that could be causing problems. Begin by removing the cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative next.

The internal chip in the key fob could be damaged by dirt or water. If your key has stopped working after being wet, you need to clean the electronic component with isopropyl alcohol or an electronic cleaner prior to installing the battery. If it is not working after exposure to salty or soapy water the chip is likely damaged and needs to be replaced.

A defective antenna module fuse could also be the cause. It's the fuse that transmits an electronic signal to the vehicle to lock or unlock. Based on the model you have, the fuse is located in a variety of places including the engine bay, on the side of the dashboard, under the rear seat ibiza car key replacement, or in the trunk.
