Utilizing a thumb nail or small screwdriver with a flat head (A) and pull upwards the key fob battery compartment cover (B). Replace the CR2025 coin battery by ensuring it is placed in the correct direction and polarity.
Dead Coin Battery
The most frequent reason for a key fob to not lock or unlock your car is a dead coin battery. If it fails you will notice a decrease in range or no power. It is easy to replace it with a fresh one (CR2025) from a local supermarket. Be aware that using the wrong or incompatible batteries can damage your key fob. Be sure that the replacement battery is the same size and voltage, and also the same specifications.
If your device was exposed to clean water such as rain or soapy tap water it is likely that the chip inside has been damaged due to corrosion. You could clean the chip with isopropyl or electronic cleaners to see if this can help, but that the chip has been damaged.
The most simple solution is to purchase an entirely new key fob. Most major car dealers sell keys and can be installed by a skilled mechanic. You can also buy them on the internet, for instance on eBay. It is recommended to work on a surface that is equipped with adequate lighting. It makes it easier to work with the smaller parts.

Water Damage
If your key fob gets wet from dropping it into the pool or by slipping it in the washing machine, you may think that it's lost but there's hope. The problem begins when the circuit board inside the fob comes in contact with water - it makes an excellent conductor and cuts off components. It also speeds up corrosion and rust.
This is a simple fix. Simply find something absorbent and place it inside the fob. A paper towl or tissue works well. Use a cotton swab soaked in isopropyl to cleanse the circuit board and any other components. Let the fob air dry in a dry, warm environment for a few weeks.
Once the fob is been drained then replace the battery with a new one (of the same size and polarity ('+' directed upwards). It can be difficult to open up the fob to access the battery, but if you have a small screwdriver with a flat head handy it should slide in easily. Once the fob has been rebuilt, it should operate just as normal. If it does not work you may need to re-program it or replace the module.
Radio Interference
When a key fob working correctly, it sends a radio frequency signal, which is received by the receiver module in your car. However, if the signal is damaged in any way your key fob will not function properly. This may be due to things, weather conditions or other transmitters operating in the same frequency range near your car.
This could cause your key fob's button to not work the vehicle's features like the ignition switch, or the security system. In this situation it is best to replace the battery on your key fob.
A few LED lighting products which uses the same frequency as key fobs for remote control may interfere with the signal, stopping it from reaching receiver modules. To prevent interference, the LED lights must be turned 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 will aid in diagnosing the issue by revealing what's wrong with your system. The scanner will ask for details about your vehicle like the make and model along with the engine type and VIN number.
Faulty Receiver Module
The key fob houses an encoder module that transmits the signals for locking and unlock. If this module fails then all the on-board electronics will cease to function. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob itself may aid.
There are a variety of possible reasons for this problem, including the battery of the coin is dead, water damage or signal interference. replacement seat key can reset the on-board computer by disconnecting the 12 Volt batteries for 15 mins. This will drain any residual electric current that could cause problems. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order first, positive second.
The internal chip in the key fob can be damaged by water or dirt. If your key's function stopped after being wet, wash the electronic component with isopropyl Alcohol or an electronics cleaner before reinstalling the battery. If the key stopped working after exposure to salted or soapy water, it's likely that the chip has been damaged and needs to be replaced.
Another possibility is a faulty antenna module fuse that transmits the lock and unlock signal to the vehicle. Depending on your model the fuse could be located in a variety of places including the engine bay, on the side of the dashboard, beneath the rear seat, or trunk.
