Dead Battery

Key fob batteries usually last for a long time, but they can die at any time.

If the key fob does not respond it means the battery is dead and has to be replaced.

Buttons Aren't Responding
If you have been driving your car for a while and you notice that the buttons on your keys aren't working, it could be an issue with worn-out buttons or sensors. The buttons that are made of rubber on most fobs will wear down with time. This can cause them to work correctly if they are pushed in a specific way or when pressure is high.

Keychain Loop Breaks
If the key fob's keychain loop is damaged, it can break off from your keys and no longer be used to lock or unlock your car. The keychain loop is easily replaced.
Key fobs may also fail due to moisture and water damage. The signs include a decreased range of operation, or no functionality at all. The problem can be resolved by replacing the battery and drying the key fob, but in certain cases, repair or replacement by a professional might be required.
Over time the buttons on key fobs can wear out and become less responsive or ineffective. It is possible to replace the key fob's button or case, but reprogramming can often solve this issue. Signal interference from nearby electronic devices may affect the connection between your key fob and your vehicle and cause problems in unlocking or locking. It could be necessary to conduct a diagnostic check at the dealership in order to resolve the issue. This is typically the case for older electric key fobs that use infrared signals and require clear line-of-sight in order to function, but most modern microchip key fobs rely on radio frequency challenge-response authentication to communicate with your vehicle.
Pairings that are corrupted or lost
Over time the batteries of keyfobs degrade. If the battery has lost a lot of its charge, the remote may not respond to commands. Replacing the battery will usually solve the issue, however you may also need to change the programming of the remote.
Modern cars come with key fobs that can control many functions. They can raise and lower windows, trigger the alarm as well as switch on the interior lights and even start some vehicles.

It is recommended to keep your owner's manual nearby when you use your key fob, to be able to refer to the specific sections that deal with the different features of your vehicle.
Another reason that can cause a fob's malfunctioning is that the remote's signal has been corrupted or gone missing. Certain of the most recent key fobs employ sophisticated encryption techniques to keep thieves from intercepting signals and generating unauthorized keys or remotes that can unlock a car. You'll likely need to visit an auto locksmith or dealer to re-program the fob and restore its functionality.
Certain automakers offer their own instructions for do-it-yourself key fob reprogramming. Most of the time, these procedures are easy enough to be done at home. However, the process is usually not a good option for those who are not experienced with electronic experience. It is recommended to leave this sort of work to experts.
Key fobs undergo plenty of wear and tear, particularly when they are used frequently and handled. The buttons on a key fob may be tossed around and the case could crack or break. It is important to have an extra key fob on you at all times since it can save you time and trouble if your remote stops working while you're out and about. Keep it close to your bed at all times, so that you can press the panic button in the event that you hear noises at night.
