Dead Coin Battery
The most frequent reason for a key fob that does not lock or unlock your car is a dead battery. If it fails you'll notice a decrease in range or no power. It is simple to replace it with a new one (CR2025) from a 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 battery you purchase is identical in size, specifications and voltage as the older one.
If your fob has been exposed to clean water, like rainwater or soapy water from the tap it is possible that corrosion has caused damage to the chip's electronic circuit. You may try cleaning the chip with isopropyl alcohol or an electronic cleaner to check if it works but it is likely that the chip has fried.
The simplest solution is to buy an entirely new key fob. Major car dealers sell them and they can be installed by a skilled mechanic. You can also buy them online, like on eBay. The best thing to do is to work on a flat, level surface with adequate lighting. It is easier to work with the smaller parts. You'll also be able to avoid placing things in the wrong spot. Always keep the key fob in a secured and safe space.
Water Damage
You may think your key fob is ruined if you drop it into a pool or accidentally wash it. But there's a way to salvage it. The problem is when the circuit board within the fob is in contact with water. It creates an excellent conductor and shorts components. It also speeds up the process of rust and corrosion.
This is a simple solution. Find something absorbent to put inside the fob. A tissue or paper towel will be ideal. Use a cotton swab that contains isopropyl for cleaning the circuit board, as well as any other components. The fob should dry for several days in a dry, warm environment.
Replace the battery after the fob is dry with a new one with the same dimensions and polarity ('+' (pointing upwards). It can be difficult to open the fob to get access to the battery, however if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily. After the fob has been reassembled, it should work just as normal. If it fails you may need to re-program it or replace the module.
Radio Interference
If a keyfob works properly, it broadcasts a radio frequency that is received by a receiver module inside your vehicle. If the signal is disrupted, your key fob won't function. This may be due to weather conditions, objects or other transmitters operating within the same frequency band close to your car.
In this instance it is best to replace the battery in your key fob. It is recommended to replace your key fob's battery.
Some LED lighting accessories that utilizes the same frequencies as a remote control key fob can interfere with the signal, stopping it from reaching receiver modules. The LED lighting must be turned off or switched to a different frequency in order to be able to avoid interference.
If you have a brand new battery in your key fob, and the issue persists, it is possible that the antenna of your key fob is damaged or not functioning properly. This is significant since the antenna is responsible for sending a signal from the key fob to the receiver module. An OBDII scan will aid in diagnosing the issue by telling you exactly what's wrong with the system. The scanner will request details about your particular vehicle, such as the model and make, engine type, and VIN number.
Faulty Receiver Module
The key fob comes with a receiver module that transmits signals to lock and unlock the key fob. If this module fails that causes it to fail, the entire onboard electronics will cease to function. If this happens Reprogramming using an OBDII scanner or replacing the key fob itself may aid.
This issue could be caused by a dead coin-cell battery either from water damage or signal interference. Try resetting the on-board computer by disconnecting the 12 volt battery for 15 minutes. This will remove any remaining electricity that could be causing problems. Begin by removing your cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.
The internal chip in the key fob can also be damaged by water or dirt. If the key fob you purchased stopped working after getting wet, clean it with isopropyl, or an electronics cleaner. Then reinstall the battery. If it has stopped working after exposure to salty or soapy water the chip could be damaged and should be replaced.
Another possibility is a defective antenna module fuse, which transmits the lock and unlock signal to the vehicle. The fuse may be located in a variety of locations, based on the model. For example it could be beneath the rear seat or trunk, or on the side of the dashboard.
