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 is likely to show symptoms before it dies like a lower range or no power at all. It is simple to replace it with a brand new (CR2025) one from your local store. Be aware that faulty or unsuitable batteries may damage the key fob. Make sure the battery you replace has the same size and voltage, and has the same specifications.

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

The simplest option is to buy an entirely new key fob. They are available from most major car dealers and are installed by a qualified mechanic. They can also be purchased on the internet from sites like ebay. The best method is to work on a flat surface with good lighting. This makes it easier to work on small parts inside. It also allows you to avoid putting things in the wrong place. Always keep the key fob in a secure and safe area.

Water Damage

You may think that your key fob is destroyed if drop it in the water or accidentally wash it. There's a chance. When the circuit board in the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also speeds up corrosion and rust.

This is an easy solution. Find something absorbent and place it inside the fob. A paper towl or tissue is ideal. Make use of a cotton swab and isopropyl to clean the circuit board, and any other components. Let the circuit board dry for a few days in a dry, warm environment.

After the fob has been drained it is time to replace the battery another one of the same size and polarity ('+' with the upwards direction). It can be difficult to open up the fob to reach the battery, however if you have a small screwdriver that is flat handy it should slide in easily. Once the fob is assembled and working, it should operate as usual. If it fails you may need to program it again or replace the module.

Radio Interference

When a key fob functioning correctly, it transmits a radio frequency signal that is picked up by the receiver module in your car. If the signal is disrupted the key fob won't work. This could be due to objects or weather conditions, or other transmitters that operate on the same frequency near your vehicle.

This can cause your key fob to not be able to activate the vehicle's functions like the ignition switch, or the security system. In this situation it is recommended to replace the battery in your key fob.

Some LED lighting aftermarket that utilizes the same frequencies as a key fob for remote control can interfere with the signal, stopping it from reaching receiver modules. To prevent interference, the LED lighting should be turned off or to the opposite frequency.

If the issue persists after installing a new battery, the antenna on the key fob might be damaged or inoperable. This is because the antenna is responsible for sending a signal from the key fob to the receiver module. An OBDII scan will aid in diagnosing the issue by revealing exactly what's wrong with the system. The scanner will ask you for details about the vehicle you own including the make and model as well as the engine type and VIN number.

Faulty Receiver Module

The key fob houses a receiver module that transmits the signals to lock and unlock. All electronic components on board will cease functioning if this component has a problem. Reprogramming the key fob by an OBDII scan or replacing it might help.

There are a few possible causes for this issue that could be the cause, such as a dead coin battery, water damage, or signal interference. Try resetting the computer on board by disconnecting the 12 volt battery for 15 minutes. This will draw out any remaining electrical energy that could cause issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.

Dirt and water can harm the internal chip of the key fob. If your key fob stops working after getting wet, wipe it using isopropyl or an electronic cleaner. Then, reinstall the battery. If it stopped working after exposure to soapy or salty water the chip may be fried and will need to be replaced.

A damaged antenna module fuse could also be the cause. This is the fuse that sends an indication to the vehicle to lock or unlock. Depending on the model the fuse can be located in one of the many locations like the engine bay, to the left of the dashboard, under the rear seat leon spare key cost mii replacement key (read more on Tyc`s official blog), or trunk.
