With a thumb nail, or a small flat head screwdriver (A) and pull upwards the key fob battery compartment cover (B). Replace the CR2025 coin battery to ensure that it's in the correct direction and in the right polarity.
Dead Coin Battery
The most frequent reason for a key fob to not be able to lock or unlock your vehicle is a dead coin battery. It usually shows indications before it dies, such as a decreased range or no power at all. It is easy to replace it with a new one (CR2025) from the local supermarket. You should be aware that using the wrong or non-compatible batteries could cause damage to your key fob. Make sure that the replacement battery is the same size and voltage and also the same specification.
If your device has been exposed to clean water, like rainwater or soapy tap water It is likely that corrosion has damaged the chip's electronic circuit. You can try cleaning the chip with isopropyl alcohol or an electronic cleaner to try to see if this helps but it is likely the chip is damaged.
A new key fob is the easiest solution. They are available at most major car dealers and can be fitted by a skilled mechanic. You can also buy them on the internet, for instance on eBay. It is best to work on a surface that has good lighting. This makes it easier to work on the smaller parts inside. This also helps you to avoid putting anything back in the wrong place. Always work on your key fob in a location that is safe and secure.
Water Damage
You may think that your key fob is damaged if you drop it in the water or accidentally wash it. But there's still hope. The problem begins when the circuit board within the fob is in contact with water. It is a great conductor and cuts off components. It also accelerates corrosion and rust.
Luckily, this is a simple issue to fix. Simply find something absorbent and place it inside the fob. Paper towl or tissue works well. Use a cotton swab with isopropyl to wash the circuit board, as well as any other components. Let the fob air dry in a dry, warm environment for a few weeks.
Replace the battery after the fob is dried out by replacing it with a new one that has the same dimensions and the same polarity ('+' (pointing upwards). The fob can be difficult to open to get to the battery, however when you have a flat head screwdriver it should be easy to slide in. After the fob is reassembled and working, it should operate just as normal. If it doesn't, you might require reprogramming it or replace the receiver module.
Radio Interference
If a keyfob works correctly, it emits a radio frequency that is picked up by a receiver module inside your vehicle. If the signal is disrupted, your key fob will not work. This could be due to factors like weather conditions, objects, or other transmitters operating on the same frequency close to your car.
This can cause your key fob to not activate the vehicle's features such as the ignition switch, or the security system. It is best to replace the battery in your key fob.
A few aftermarket LED lighting fixtures that uses the same frequency as the remote key fob may interfere with the signal, preventing it from reaching the receiver modules. The LED's light source must be switched off or changed to a different frequency to avoid interference.
If the issue is still present after installing a new battery, the antenna of the key fob might be damaged or inoperable. This is important since the antenna is responsible for sending an indication from the key fob to the receiver module. An OBDII scan will help diagnose the problem by revealing what's wrong with the system. The scanner will request information about your specific vehicle including the model and make along with the engine type and VIN number.
Faulty Receiver Module
The key fob is equipped with a receiver module that transmits the signals for locking and unlock. If this module develops a fault, all of the on-board electronics will cease to function. Reprogramming the keyfob using 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. It is possible to reset the on-board computer by disconnecting the 12 Volt batteries for 15 mins. This will remove any remaining electricity that may cause issues. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order first: positive, then negative second.
The internal chip of the key fob can also be damaged by dirt or water. If your key stopped working after it got wet, wipe the electronic component with isopropyl ethanol or an electronics cleaner before reinstalling the battery. If your key has stopped working after exposure to soapy or salted water, it's likely that the chip has become damaged and needs to be replaced.
A faulty antenna module fuse may also be the cause. This is the fuse that transmits an alert to the vehicle to lock or unlock. Depending on your model the fuse can be located in a variety of places like the engine bay, the side of the dashboard, under the rear seat, or trunk.
