Dead Coin Battery
The most frequent reason for a key fob that does not allow you to 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 (CR2025) one from a local retailer. Be aware that incorrect or defective batteries could cause damage to the key fob. Make sure that the new battery is identical in size, specifications and voltage as the older one.
If your fob was exposed to clean water like rain or soapy tap water, it is likely that the electronic chip inside has been damaged by corrosion. You could clean the chip with isopropyl or electronic cleaners to determine if that helps, but that the chip has been damaged.

Water Damage
You may think your key fob is lost if you drop it in the water or accidentally wash it. But there's a way to salvage it. The problem begins when the circuit board within the fob is in contact with water - it makes an excellent conductor and cuts off components. It also accelerates corrosion and rust.
Luckily, this is simple to fix. Find something absorbent to place inside the fob. A tissue or a paper towel will be ideal. Then, use a cotton swab dipped in isopropyl alcohol to wipe down the circuit board and other components to remove any battery acid residue and contamination. Let the circuit board dry for a few days in a warm and dry environment.
When the fob has been drained, replace the battery with a new one (of the same size and polarity ('+' with the upwards direction). The fob isn't easy to open to get to the battery, however if you keep a flat-head screwdriver at hand it will be a breeze to insert. Once the fob is assembled, it should work as usual. If it doesn't, you might have to reprogramme it or replace the receiver module.
Radio Interference
When a key fob functioning properly, it sends an audio frequency signal that is picked up by the receiver module in your car. However, if the signal is disrupted in some way the key fob will not work properly. This could be due to objects, weather conditions, or other transmitters that operate on the same frequency in close proximity to your vehicle.

If the problem persists after replacing the battery, the antenna on your key fob could be damaged or inoperable. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will ask to provide information about your vehicle, including the make, model, engine type and VIN number.
My Web Site has an encoder module that transmits the signals needed to lock and unlock. If the receiver module develops a fault then all the on-board electronics will cease to function. Reprogramming the keyfob using an OBDII scan or replacing it might help.
There are a number of possible causes that could be the cause, such as the battery of the coin is dead, water damage or signal interference. You can reset your on-board computer if you disconnect the 12 Volt batteries for 15 minutes. This will remove any remaining power that could be causing problems. Begin by removing your cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order first, positive second.
Water or dirt can also affect the internal chip inside the key fob. If your key fob stops working after being soaked, clean it with isopropyl or electronics cleaner. Then, you can reinstall the battery. If it has stopped working after exposure to soapy or salty water the chip could be damaged and needs to be replaced.
A defective antenna module fuse could also be the cause. This is the fuse that sends an alert to the vehicle to lock or unlock. The fuse may be located in a variety of locations, based on the type of vehicle. For example it could be located under the rear seat or trunk, or the side of the dashboard.
