Use a small screwdriver or a thumbnail (A) to pry up the battery compartment cover on the key fob (B). Replace the CR2025 battery, making sure it is installed in the correct direction.

Dead Coin Battery

A dead battery for a coin is the most frequent 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 easy to replace with a new one (CR2025) from an area supermarket. You should be aware that using the wrong or non-compatible batteries can cause damage to your key fob. Make sure that the new battery is the same size, specification and voltage as the older one.

If your device was exposed to clean water such as rain or soapy tap water, it is possible that the chip inside has been damaged by corrosion. You can try cleaning the chip with alcohol or an electronic cleaner to check if it works but it is most likely that the chip has fried.

The most straightforward option is to buy a new key fob. They are available at most major car dealers and are installed by a qualified mechanic. You can also purchase them online, for example on eBay. It is recommended to work on a surface that is equipped with good lighting. It is much easier to work on small pieces. This also helps you to avoid putting things back in the wrong spot. Always work on your key fob in a place that is secure and safe.

Water Damage

If your fob's key gets wet from dropping it into the pool or throwing it in the wash you might think that it's gone but there's hope. When the circuit board on the fob is exposed to water, it transforms into conductor that shorts the components. It also accelerates corrosion and rust.

Luckily, this is simple to fix. Find something absorbent to place inside the fob. A tissue or a paper towel will work well. Make use of a cotton swab and isopropyl for cleaning the circuit board as well as any other components. Let the fob air dry in a dry, warm environment for several weeks.

When the fob has been drained it is time to replace the battery an alternative of the same size and the same polarity ('+' pointing upwards). It is a challenge to open up the fob to get access to the battery but if you have a small flat-head screwdriver available, it should be able to slide into easily. After the fob is repaired, it should function just as normal. If it doesn't work then you might need to program it again or replace the module.

Radio Interference

If a key fob is functioning properly, it emits a radio frequency signal that is interpreted by the receiver module inside your car. However, if the signal is interrupted in some way, your key fob won't perform as it should. This may be due to objects, weather conditions or other transmitters operating within the same frequency band close to your vehicle.

This can cause your key fob's button to not work the vehicle's functions, such as the ignition switch or security system. In this scenario it is best to replace the battery inside your key fob.

Some LED lighting aftermarket that uses the same frequencies as the remote control key fob may interfere with the signal, stopping it from reaching receiver modules. To avoid interference, the LED light should be turned off or to another frequency.

If the problem persists after replacing the battery, the antenna on the key fob might be damaged or is malfunctioning. This is crucial since the antenna is responsible for transmitting signals from the key fob to the receiver module. The OBDII scanner is able to assist in diagnosing the problem by telling you what is wrong with the system. The scanner will ask you for details about the vehicle you own, such as 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 this module fails then all the on-board electronic components will stop functioning. If this happens Reprogramming using an OBDII scanner or replacing the key fob itself could 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 on-board computer by disconnecting the battery 12 volts for 15 minutes. This will remove any remaining electrical energy that could be causing issues. Start by removing  TheKeyLab  from the negative terminal first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.

Dirt and water can damage the internal chip of the key fob. If your key fob stopped working after being wet, wash it with isopropyl or electronic cleaner. Then reinstall the battery. If the key ceases to function after being exposed to salted or soapy water, it's likely that the chip has been fried and needs to be replaced.

A defective fuse for the antenna module could also be the reason. It's the fuse that sends an electronic signal to the vehicle to lock or unlock. The fuse may be located in several places, depending on the type of vehicle. For instance it could be beneath the rear seat, or in the trunk, or on the side of the dashboard.
