Using a thumb nail or small screwdriver with a flat head (A) to lift up the key fob battery compartment cover (B). Replace the CR2025 coin battery and ensure it's in the correct direction and polarity.

Dead Coin Battery

A dead battery on a coin is the most frequent cause of a key fob not locking or unlocking your vehicle. After it has died you will notice a decrease in range or no power. It is easy to replace it with a fresh one (CR2025) from an area supermarket. 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, and that it is the same specification.

If your device has been exposed to clean water, such as rainwater or soapy tap water It is probable that corrosion has damaged the electronic chip. You can clean the chip with isopropyl or electronic cleaners to see if it helps, but it's likely the chip is fried.

The simplest solution is to purchase a new key fob. They are available from most major car dealers and are fitted by a professional mechanic. You can also purchase them online, for example on eBay. The best thing to do is to work on a flat, level surface with good lighting. It is easier to work with the small parts. This can also help to avoid placing anything back in the wrong location. Always work on your key fob in a location that is secure and safe.

Water Damage

If your fob's key gets damaged by dropping it in the pool or fumbling it in the wash, you may think that it's gone but there's hope. When the circuit board in the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also accelerates corrosion and rust.

Fortunately, this is not difficult to fix. Find something absorbent and place it inside the fob. A paper towl or tissue can be used. Use a cotton swab soaked in isopropyl for cleaning the circuit board as well as any other components. Allow the circuit board to air dry in a warm, dry environment for a few weeks.

After the fob has dried out, replace the battery with a new one of the same size and the same polarity ('+' that is pointing upwards). The fob might be difficult to open to get to the battery, but should you have a flat-head screwdriver, it should be easy to insert. Once the fob has been rebuilt, it should operate as normal. If it doesn't work, you'll require reprogramming it or replace the receiver module.

Radio Interference

If a key fob is functioning correctly, it transmits a radio frequency signal that is interpreted by the receiver module inside your car. If the signal is damaged in some way, your key fob won't function properly. This may be due to things, weather conditions or other transmitters operating on the same frequency band near your vehicle.

In this case it is recommended to replace the battery on your key fob. In this case it is recommended to replace the battery inside your key fob.

Some LED lighting accessories which uses the same frequency as the remote control key fob can interfere with the signal, preventing it from reaching receiver modules. The LED lighting must be switched off or changed to a different frequency to keep out interference.

If you have a brand new battery in your key fob and the issue persists, it is possible that the key fob's antenna is damaged or inoperable. The antenna is responsible for transmitting signals between the key fob and the receiver module. A scan of the OBDII can help you identify the issue by revealing exactly what's wrong with the system. The scanner will ask for details about your vehicle, including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob features a receiver module that transmits signals to lock and unlock the key fob. If this module is damaged that causes it to fail, the entire onboard electronics will stop working. If this happens it is possible to reprogramme the module using an OBDII scanner or replacing the key fob itself may help.

There are a variety of possible causes, including a dead coin battery water damage, or signal interference. It is possible to reset the on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will flush out any residual electricity that could be causing problems. Begin by removing your cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. Positive first, then negative second.

The internal chip inside the key fob can also be damaged by water or dirt. If your key fob stopped functioning after being wet, wash it using isopropyl or an electronic cleaner. Then, reinstall the battery. If it has stopped working after exposure to salty or soapy water the chip is likely fried and will need to be replaced.

Another possibility is a damaged antenna module fuse that is sending the signal to lock or unlock to the vehicle. The fuse could be found in various places, based on the model. For example it could be beneath the rear seat exeo key programming, or in the trunk, or on the side of the dashboard.
