Using a thumb nail or small flat head screwdriver (A) to lift up the key fob compartment cover (B). Replace the CR2025 battery and ensure that it is placed in the correct direction.
Dead Coin Battery
The most common reason for a key fob to not unlock or lock your car is a dead battery. It will usually show indications before it dies, like a decrease in range or no power at all. It is easy to replace it with a new one (CR2025) from an area supermarket. Be aware that incorrect or unsuitable batteries may damage the key fob. Be sure that the battery you replace has the same size and voltage, and has the same specifications.
If your fob has been exposed to clean water, such as rainwater or soapy tap water It is probable that corrosion has damaged the chip's electronic circuit. You can clean the chip with isopropyl or electronic cleaners to see if this aids, but that the chip has been damaged.
A new key fob is the easiest solution. Most major car dealers sell keys and can be installed by an experienced mechanic. They can also be bought online from places like ebay. It is best to work on a surface with adequate lighting. This will make it easier to work on the smaller parts inside. You will also be able to avoid placing things in the wrong spot. Always keep the key fob in a secure and safe space.
Water Damage
You might think that your key fob is destroyed if drop it in the pool or accidentally wash it. However, there's still a chance. The issue begins when the circuit board in the fob comes into contact with water. It makes an excellent conductor, and it shorts out the components. It also speeds up the process of rust and corrosion.
This is a simple fix. Find something absorbent, and put it inside the fob - paper towl or tissue can be used. Make use of a cotton swab and isopropyl to cleanse the circuit board and any other components. Let the fob air dry in a warm, dry environment for a few weeks.
Replace the battery after the fob is dry with a fresh one that is the same dimensions and the same polarity ('+' (pointing upwards). It isn't easy to open the fob in order to access the battery, however if you have a small flat-head screwdriver that you have at hand, it will be able to insert easily. Once the fob is assembled and working, it should operate just as normal. If it doesn't work, you may have to re-program it or replace the module.
Radio Interference
If a key fob is functioning correctly, it transmits a radio frequency signal that is received by the module in your car. If the signal is interrupted the key fob won't function. This can be caused by objects or weather conditions, or other transmitters operating at the same frequency close to your car.
This could cause your key fob to not activate the vehicle's functions for example, the ignition switch, or the security system. It is best to replace the battery on your key fob.
Some LED lighting from the aftermarket that utilizes the same frequency as a remote key fob could interfere with the signal and stop it from reaching the receiver modules. To avoid interference, the LED lights must be switched off or switched to a different frequency.
If the issue continues to persist after replacing the battery, the antenna of the key fob might be damaged or not functioning properly. This is significant because the antenna is responsible for transmitting signals from the key fob to the receiver module. An OBDII scan can help diagnose the problem by revealing exactly what's wrong with the system. The scanner will ask for details about your car, including the model, make engine type, VIN number.
Faulty Receiver Module
The key fob features a receiver module that sends signals to lock and unlock the key fob. If the receiver module fails then all the on-board electronics will cease to function. Reprogramming the key fob using an OBDII scan or replacing it might help.
This problem could be caused by a dead coin-cell, water damage or signal interference. You can try resetting the computer on board by disconnecting the 12 volt battery for 15 minutes. This will draw out any remaining electricity that may be causing problems. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.
The presence of dirt or water could cause damage to the internal chip of the key fob. If replacement seat key stopped functioning after being soaked, clean it with isopropyl or electronic cleaner. After that, replace the battery. If it is not working after exposure to salty or soapy water the chip could be damaged and needs to be replaced.
Another possibility is a damaged antenna module fuse, which transmits the signal to lock or unlock to the vehicle. Depending on your model the fuse can be located in one of several locations, such as the engine bay, the side of the dashboard, under the rear seat, or in the trunk.
