With a thumb nail, or a small screwdriver with a flat head (A), prise upwards the key fob battery compartment cover (B). Replace the CR2025 coin battery to ensure that it is fitted in the correct direction and polarity.

Dead Coin Battery

A dead battery for a coin is the most frequent cause of a key fob not locking or unlocking your vehicle. It will usually show symptoms before it dies like a decrease in range or no power at any time. It is easy to replace with a brand new one (CR2025) from an area supermarket. Be aware that using the wrong or non-compatible batteries can damage your key fob. Make sure that the replacement battery is the same size and voltage, and also the same specification.

If your device 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 might try cleaning your chip with alcohol or an electronic cleaner to see if it helps but it is more likely that the chip has been damaged and fried.

A new key fob is the most straightforward solution. They are available at most major car dealers and can be fitted by an experienced mechanic. They can also be purchased on the internet from sites like ebay. It is best to work on a surface that is equipped with good lighting. This makes it easier to work on the small parts inside. You’ll also be able to avoid placing things in the wrong place. Always work on your key fob in a location that is safe and secure.

Water Damage

You might think that your key fob is lost if you drop it in a pool or accidentally wash it. But there’s still hope. If the circuit board inside the fob is exposed to water, it transforms into a conductor that shorts out the components. It also speeds up the process of rust and corrosion.

Luckily, this is a simple issue to fix. Find something absorbent and place it inside the fob. Paper towl or tissue is ideal. Use a cotton swab that contains isopropyl for cleaning the circuit board, and any other components. Allow the circuit board to air dry in a warm, dry environment for several weeks.

After the fob has been drained, replace the battery with another one of the same size and the same polarity (‘+’ that is pointing upwards). It can be tricky to open up the fob to get access to the battery, but if you have a small screwdriver with a flat head at hand, it will slide in easily. Once the fob is assembled it should function just as normal. If it fails, you may have to program it again or replace the module.

Radio Interference

If a keyfob works properly, it transmits a radio frequency that is received by a module in your vehicle. However, if the signal is damaged in some way your key fob will not work properly. This may be due to things, weather conditions or other transmitters operating within the same frequency band near your vehicle.

In this case, it is best to replace the battery in your key fob. It is best to replace the battery in your key fob.

Some aftermarket LED lighting that uses the same frequency as the remote key fob may interfere with the signal, preventing it from reaching the receiver modules. To avoid interference, the LED light must be turned off or to an alternative frequency.

If the issue continues to persist after installing a new battery, the antenna of your key fob may be damaged or not functioning properly. This is crucial since the antenna is responsible for sending a signal from the key fob to the receiver module. The OBDII scanner is able to aid in identifying the issue by revealing what’s wrong with the system. The scanner will ask you for details about the vehicle you own like the make and model of the vehicle, the type of engine, and VIN number.

Faulty Receiver Module

The key fob features a receiver module that transmits signals for locking and unlocking. If the receiver module is damaged then all the on-board electronic components will stop functioning. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob could assist.

There are a variety of possible causes for this issue, including an empty coin battery, water damage, or signal interference. It is possible to reset the on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will flush out any residual electric current that could cause issues. Begin by removing your 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.

The internal chip inside the key fob can be damaged by dirt or water. If the key fob you purchased stopped working after being soaked, clean it with isopropyl, or an electronics cleaner. Then, reinstall 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 damaged antenna module fuse could also be the cause. It is the fuse that transmits an indication to the vehicle to lock or unlock. The fuse could be found in a variety of locations, based on the model. For example it could be under the rear seat keys or trunk, or on the side of the dashboard.
