Battery
The most frequent reason for a key fob not working is the battery is dead. The battery used in the fob is a 3V lithium button-cell battery (CR 2032). The battery is available in retailers or online. Replace the old battery with one of the same type, size and specification. Utilizing a different type of battery could damage the fob.
The battery is encased within the fob by clips for retaining, which complete an electric circuit when the remote is turned on. These can cause shorts if they're dirty or loose. This will stop the remote from functioning. Clean them with isopropyl alcohol or electronic cleaner.
To replace the battery, you will need to remove the fob. This can be done by inserting a screwdriver through the seam. Replace the battery with a brand new one. Be sure to place it in the same direction. The fob will then shut itself automatically. After changing the battery, it is important to test that the fob works properly.
Water Damage
Water damage may be the reason for the key fob not working after dropping it in a pool or washed it in a washer. The electronic chip inside the key fob is protected by rubber seals, but prolonged exposure to water will reduce the effectiveness of these seals over time. Water is also a great conductor, which can lead to short circuits in the key fob.
The key fob battery can be replaced easily. Use a small screwdriver or thumb nail to pull off the cover on the key fob's battery compartment. Insert a new button-cell battery CR2025, ensuring the polarity faces upwards. Close the keyfob's battery compartment to reprogram the remote so that it will work with your car.
If your key fob still isn't working after replacing the battery and reprogramming it then it's possible that the receiver module has developed an issue. The receiver module receives the signals from your key fob and sends them into your car to control the central locking, ignition, and engine.
Faulty Chip

Faulty Receiver Module
In rare instances when the key fob has stopped working and all other steps have been performed (including replacing the battery or reconfiguring) this may indicate an issue with the receiver module. This is a small black box in the key fob that transmits the signal to control your car's keyless system.
The most common reason for the receiver module to stop working is a dead battery for the coin. This is the first thing that should be replaced if this is the case. Ensure that the new battery has the same size specifications, voltage and specification as the old one.
Water damage is another frequent problem. If your fob has been exposed to pure tap water or rain this shouldn't cause an issue, but should it have been exposed to dirty, soapy or salty water, the chip inside might have been damaged. Before reusing the fob, it is best to open it up and check all mechanical parts for signs of corrosion or damage. It is also worth checking the wiring and ensuring it is correctly connected.
Radio Interference
When the key fob's signal is disrupted by interference, it may prevent the vehicle from responding to the remote control. This can be caused a variety of ways, such as radio transmissions by other devices operating on the same frequency as the keyfob. The signal could also be masked by signals that are too strong in intensity.
It is crucial to remember that a dead battery is a common reason for a key fob that is not functioning and should be the first thing to be to be examined. If the key fob has had its battery replaced recently and the range has decreased it is a sign that the battery is damaged.
It is recommended that you use a new battery for replacement and ensure that the proper size and voltage are utilized. It is also advisable to ensure that the polarity of the battery is in the exact direction when it is inserted. This will avoid damage to the chip in the key fob. If the battery has been damaged by water, the chip may need to be cleaned with isopropyl alcohol or electronic cleaner.
