With a thumb nail, or a small screwdriver with a flat-headed head (A), prise upwards the key fob compartment cover (B). Replace the coin battery CR2025 by ensuring it is placed in the proper direction and polarity.
Dead Coin Battery
The most frequent reason for a key fob to not lock or unlock your car is a dead battery. After it has died you will see a decrease in range or no power. It is easy to replace with a new one (CR2025) from the local supermarket. Be aware that incorrect or defective batteries could damage the key fob. Make sure that the new battery is identical in size, specifications and voltage as your old one.
If your device was exposed to clean water, such as rain or soapy tap water, it is possible that the electronic chip inside has been damaged due to corrosion. You could clean the chip with isopropyl or electronic cleaners to see if that helps, but it's likely the chip is damaged.
A new key fob is the easiest solution. They are readily available from major dealerships and can be fitted by a skilled mechanic. They can also be bought online from places like ebay. It is recommended to work on a surface with good lighting. It is much easier to work on the smaller parts. You will also be able to avoid putting 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 still hope. When the circuit board on the fob is exposed to water, it develops a conductor that shorts out the components. It also increases corrosion and rust.
Luckily, this is a simple issue to fix. Simply locate something absorbent and place it inside the fob. Paper towl or tissue works well. Make use of a cotton swab and isopropyl to wash the circuit board, and any other components. The fob should dry for a few days in a dry and warm environment.
Once the fob is been drained, replace the battery with another one of the same size and the same polarity ('+' with the upwards direction). The fob might be difficult to open to get to the battery, but If you have a flat-head screwdriver in your toolbox it will be simple to insert. Once the fob is assembled, it should work as usual. If it does not work, you may have to re-program it or replace the module.
If a keyfob works properly, it sends out an audio frequency that is absorbed by a receiver module inside your car. If the signal is not received, your key fob will not function. This could be due to objects or weather conditions, or other transmitters that operate at the same frequency as your car.
This can cause your key fob's button to not work the vehicle's features such as the ignition switch or security system. It is best to replace the battery in your key fob.
Some LED lighting aftermarket which uses the same frequency as a remote control key fob may interfere with the signal, stopping it from reaching receiver modules. The LED lighting must be turned off or switched to a different frequency to keep out interference.
If you have a brand new battery in your key fob and the issue persists, it's likely that the antenna on your key fob is damaged or inoperable. This is important because the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scan will help diagnose the problem by telling you exactly what's wrong with the system. The scanner will request details about your vehicle including the model and make, engine type, and VIN number.
Faulty Receiver Module
The key fob contains the receiver module which transmits the signals needed to lock and unlock. If this module fails then all the on-board electronic components will stop functioning. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob could aid.
There are a number of possible causes for this issue, including a dead coin battery water damage or signal interference. It is possible to reset the on-board computer if you disconnect the 12 Volt batteries for 15 minutes. This will remove any remaining electric current that could cause issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, reconnect your battery in reverse order. Positive first, then negative the next.
Dirt and water can cause damage to the internal chip of the key fob. If your key fob stops working after being soaked, clean it using isopropyl or an electronic cleaner. After that, replace the battery. If the key ceases to function after being exposed to salted or soapy water, it's likely that the chip has become damaged and must be replaced.
Another possibility is a damaged antenna module fuse, which transmits the lock or unlock signal to the vehicle. Based on the model you have, the fuse is located in a variety of places such as the engine bay, side of the dashboard, under the rear seat, or trunk.
