Use a small screwdriver or a thumbnail (A) to open the battery compartment cover on the key fob (B). Replace the CR2025 coin battery and ensure it is placed in the correct direction and in the right polarity.

Dead Coin Battery

A dead battery on a coin is the most frequent cause of a key fob that isn't locking or unlocking your car. It usually shows signs before it dies like a lower range or no power at any time. It is easy to replace it with a brand new (CR2025) one from your local store. Be aware that using the wrong or non-compatible batteries can cause damage to your key fob. Make sure that the battery you purchase is identical in size, specifications and voltage as the older one.

If your device has been exposed to pure water, such as rainwater or soapy water from the tap, it is likely that corrosion has caused damage to the chip's electronic components. You could clean the chip with isopropyl or electronic cleaners to see if it helps, but it's likely the chip is damaged.

A new key fob is the simplest solution. The majority of major car dealers sell key fobs and they can be installed by a skilled mechanic. You can also purchase them on the internet, for instance on eBay. The best way to work is to work on a level surface with adequate lighting. The Keylab is much easier to work on small parts. This will also allow you to avoid putting anything back in the wrong spot. Always keep your key fob in a location that is secure and safe.

Water Damage

You might think that your key fob is destroyed if drop it in the water or accidentally wash it. There's a chance. The issue begins when the circuit board inside the fob comes into contact with water. It creates a fantastic conductor and cuts off components. It also speeds up the process of corrosion and rust.

Luckily, this is simple to fix. Find something absorbent and place it inside the fob - paper towl or tissue work well. Then apply an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to clean out any battery acid residue and contamination. Let the fob dry out for some time in a warm and dry environment.

Replace the battery once the fob has dried with a fresh one with the same dimensions and polarity ('+' (pointing upwards). The fob can be difficult to open in order to access the battery, however if you keep a flat-head screwdriver at hand it will be a breeze to slide in. Once the fob has been repaired, it should function like a normal. If it doesn't, you may require reprogramming it or replace the receiver module.

Radio Interference

When a key fob is functioning properly, it sends the radio frequency signal which is picked up by the receiver module inside your car. If the signal is not received, your key fob will not work. This could be due objects, weather conditions or other transmitters operating in the same frequency range near your vehicle.


This can cause your key fob's button to not work the car's systems such as the ignition switch, or the security system. In this case it is recommended to replace the battery on your key fob.

A few LED lights that are aftermarket and uses the same frequency as the remote key fob may interfere with the signal and prevent it from reaching the receiver modules. To avoid interference, the LED lights must be switched off or switched to the opposite frequency.

If the issue persists after replacing the battery, the antenna of your key fob could be damaged or malfunctioning. This is crucial because the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scan will help diagnose the problem by revealing what's wrong with the system. The scanner will request details about the vehicle you own including the model and make along with the engine type and VIN number.

Faulty Receiver Module

The key fob is equipped with a receiver module which transmits signals to lock and unlock the key fob. The electronic components on the board will cease to function if this module has a problem. Reprogramming the key fob by an OBDII scan or replacing it might help.

This issue can be caused by a dead battery in the coin-cell or water damage, or signal interference. You can try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will remove any remaining power that could be causing issues. Begin by removing the cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect your battery in reverse order. Positive first, then negative the next.

Dirt or water can cause damage to the internal chip of the key fob. If your key fob stopped functioning after getting wet, clean it with isopropyl or electronic cleaner. Then, you can reinstall the battery. If it is not working after exposure to salty or soapy water, the chip is probably damaged and must be replaced.

A damaged antenna module fuse could be a cause. It's the fuse that transmits an electronic signal to the vehicle to lock or unlock. The fuse could be found in various places, based on the model. For example, it could be under the rear seat, or in the trunk, or on the side of the dashboard.
