Make use of a small screwdriver with a flat head or a thumbnail (A) to remove the battery compartment cover of the key fob (B). Replace the CR2025 coin battery by ensuring it is fitted in the correct direction and polarity.

Dead Coin Battery

The most frequent reason for a key fob to not be able to lock or unlock your car is a dead battery. After it has died you will see the decrease in range or no power. It is easy to replace it with a brand new (CR2025) one from your local supermarket. Be aware that using the wrong or unsuitable batteries could cause damage to your key fob. Make sure that the new battery has the same size, specification and voltage as your old one.

If your fob was exposed to clean water such as rain or soapy tap water it is likely that the electronic chip inside has been damaged by corrosion. You might try cleaning your chip with isopropyl Alcohol or an electronic cleaner to try to see if this helps but it is more likely that the chip has fried.

A new key fob is a simple solution. Major car dealers sell them and they can be installed by an experienced mechanic. They can also be bought online from places like ebay. The best way to work is to work on a flat, level surface with adequate lighting. This makes it easier to work on the small parts inside. You will also be able to avoid placing something in the wrong location. Always work on your key fob in a place that is safe and secure.

Water Damage

You might think that your key fob is lost if you drop it in the pool or accidentally wash it. But there's a way to salvage it. The problem begins when the circuit board within the fob comes into contact with water. It creates an excellent conductor and cuts off components. It also accelerates the process of rust and corrosion.

Luckily, this is a simple issue to fix. Find something absorbent to put inside the fob. A paper towel or tissue will work. Make use of a cotton swab and isopropyl to wash 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.

Once the fob is been drained, replace the battery with an alternative of the same size and the same polarity ('+' pointing upwards). The fob isn't easy to open to get to the battery, but if you keep a flat-head screwdriver on hand it should be easy to insert. Once the fob has been put back together, it should work like a normal. If it fails it may be necessary to program it again or replace the module.


Radio Interference

If a key fob is functioning properly, it sends a radio frequency signal that is received by the receiver module inside your car. If the signal is disrupted the key fob will not work. This can be caused by objects such as weather conditions, objects, or other transmitters that operate at the same frequency as your car.

In this instance it is best to replace the battery on your key fob. In this scenario it's best to replace the battery on your key fob.

Some aftermarket LED lighting that utilizes the same frequency as a remote key fob can interfere with the signal, preventing it from reaching the receiver modules. The LED light must be turned off or switched to a different frequency to prevent interference.

If the problem persists after replacing the battery, the antenna of the key fob might be damaged or inoperable. The antenna is responsible for transmitting a signal between the key fob and the receiver module. Using an OBDII scanner can aid in identifying the issue by telling you what is wrong with the system. The Keylab will ask you for information about your specific vehicle like the make and model, engine type, and VIN number.

Faulty Receiver Module

The key fob is equipped with the receiver module which transmits the signals for lock and unlock. If the receiver module fails, all of the on-board electronic components will stop functioning. If this is the case, reprogramming with an OBDII scanner or replacing the key fob could help.

This problem can be caused by a dead coin-cell battery either from water damage or signal interference. Try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will draw out any remaining electricity that may be causing issues. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First, positive and then negative next.

Water or dirt can also damage the internal chip of the key fob. If your key fob stopped functioning after getting wet, wipe it with isopropyl or electronic cleaner. After that, replace the battery. If the key ceases to function after exposure to salted or soapy water, it's likely that the chip has become damaged and needs to be replaced.

A defective antenna module fuse may also be the cause. It is the fuse that transmits an electronic signal to the vehicle to lock or unlock. The fuse may be located in a variety of places, based on the type of vehicle. For instance, it could be under the rear seat, or in the trunk, or the side of the dashboard.
