Remote Key Fob Repairs
If your remote key fob isn't functioning, the first thing to do is to check the battery. This is the most typical reason why your car isn't responding when you ask it for commands.
If the problem persists, it may be due to a different issue. Many of these problems can be resolved with a few easy steps.
Check the Battery
The key fob has many functions. It can lock and unlock your vehicle remotely and turn on the interior lighting, and start the engine by pressing a button. If you notice your fob isn't responding in the same way as it did too, or you have to get closer to the vehicle to lock or unlock it, your remote battery may need to replaced.
The majority of key fobs utilize a standard watch battery, usually the coin cell CR2032. They are available at most grocery and hardware stores and also at some gas stations. The inside of the fobs can vary so check the owner's manual to find out what type of battery is required. Also, keep a spare key fob handy because you never know when it could break or get lost.
A remote key fob works by transmitting the radio frequency (RF) signal to the receiver inside your vehicle. When you hit a button on the fob it transmits a unique code that matches preprogrammed codes within the system of your vehicle. The receiver in your car will then verify the signal and then opens or closes the doors in accordance with the signal. If you're having trouble with your key fob, it could require a new battery, or the codes may need to be reset.
While you wait for a new battery to arrive, you could try a few things to help your device respond more effectively. Consumer Reports states that a lot of automobiles come with a feature that lets you turn off the key-chain alarm that is on your key fob by holding down the panic or lock button for 10 seconds. This is a straightforward trick that can prevent your key fob from being activated accidentally in public. It's also a great way to keep your vehicle and yourself safe from unintentional burglaries.
You can test the battery's current condition with a multimeter and determine the voltage. The probes should be placed on the positive and the negative side of the battery. These sides should be marked with the letters P or N. A reading that is less than 3.0 Volts could indicate that the battery needs replacing.
Check the Buttons
If you are unable to get your car key fob to respond when you press its buttons, it could mean that the fob needs replacing. The buttons on the fob transmit a coded message to your vehicle's receiver. It is not uncommon to see them wear out.

Check the Connections

They use radio frequency technology (RF) to communicate with a receiver in your car that confirms and processes the signals coming in. They're a great security and convenience feature but they are also prone to stop working for all sorts of reasons, including after replacing the battery.
Key fobs are susceptible to damage caused by water, blunt force and scratches on the circuit board.

The key fob has to be functioning properly to ensure security.
If your key fob isn't able to function as expected it is possible to start by attempting to lock and unlock your car using your backup remote.

Fobs can be used to replace your metal key, or upgraded to a smart fob or proximity fob with additional features.
