Use a small screwdriver or a thumbnail (A) to break open the battery compartment cover on the key fob (B). Replace the CR2025 battery and ensure that it is inserted in the correct direction.
Dead Coin Battery
The most common reason for a key fob to not allow you to lock or unlock your car is a dead coin battery. It usually displays signs before it dies such as a decreased range or no power at any time. It is easy to replace it with a new one (CR2025) from an area supermarket. It is important to be aware that using the wrong or unsuitable batteries can damage your key fob. Make sure that the new battery is the same size, specification and voltage as the old one.
If your device was exposed to clean water like rain or soapy tap water, it is likely that the chip inside has been damaged by corrosion. You could try cleaning the chip with isopropyl alcohol or an electronic cleaner to test if it helps, but it is likely that the chip has fried.
A new key fob is the easiest solution. Major car dealers sell key fobs and they can be installed by a skilled mechanic. They can also be bought on the internet from sites like ebay. The best option is to work on a flat surface with good lighting. It is easier to work with small pieces. You'll also be able to avoid putting things in the wrong spot. Always work on the key fob in a secure and safe place.
Water Damage
If your key fob is damaged by dropping it in the pool or slipping it in the washing machine, you may think it's a goner but there's hope. When the circuit board in the fob is exposed to water, it turns into a conductor which shorts the components. It also accelerates the process of corrosion and rust.
This is a simple solution. Find something absorbent to put inside the fob. A tissue or a paper towel will work well. Then you can use an alcohol-soaked cotton swab and a cotton swab isopropyl ethanol to wipe down the circuit board as well as other components to eliminate any battery acid residue and contamination. Let the fob air dry in a warm, dry environment for a few weeks.
Replace the battery after the fob has dried with a new one that is the same size and the same polarity ('+' (pointing upwards). The fob may be difficult opening to access the battery, but If you have a flat-head screwdriver at hand it should be easy to slide in. After the fob is reassembled it should function like normal. If it fails, you may have to re-program it or replace the module.
Radio Interference
When a key fob functioning properly, it sends a radio frequency signal that is received by the receiver module inside your car. If the signal is interrupted in some way, your key fob won't function properly. This could be due to things, weather conditions or other transmitters operating on the same frequency band close to your car.
This could cause your key fob to not activate the car's systems, such as the ignition switch or security system. It is best to replace your key fob's battery.
Some LED lighting from the aftermarket that uses the same frequency as the remote key fob may interfere with the signal and stop it from reaching the receiver modules. To prevent interference, the lighting must be switched off or switched to the opposite frequency.
If the issue is still present after replacing the battery, the antenna of your key fob could be damaged or inoperable. This is important because the antenna is responsible for sending a signal from the key fob to the receiver module. Utilizing an OBDII scanner will aid in identifying the issue by telling you what is wrong with the system. The scanner will ask you for details about your particular vehicle including the make and model of the vehicle, the type of engine, and VIN number.
Faulty Receiver Module
The key fob comes with a receiver module that sends signals to lock and unlock the key fob. All electronic components that are on-board will stop working if the receiver module is affected by a malfunction. If this is the case, reprogramming with an OBDII scanner or replacing the key fob may assist.
This problem could be caused by a dead coin-cell battery, 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 could cause issues. Start by removing the cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, connect 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 your key fob stops working after getting wet, clean it with isopropyl or electronics cleaner. Then, reinstall the battery. If it stopped working after exposure to salty or soapy water the chip is likely fried and will need to be replaced.
Another possibility is a faulty antenna module fuse that transmits the lock and unlock signal to the vehicle. Based on the model you have the fuse could be located in one of several locations like the engine bay, on the side of the dashboard, beneath the rear seat, or in the trunk.
