Battery
It is not uncommon for the battery in a key fob for cars to wear out. It is fairly easy to replace batteries, but it is essential to make sure that you choose the correct type that you can refer to the owner's manual or talk to the dealer of the manufacturer to find out what kind of battery you need. It is recommended to examine the battery compartment with care, as dead batteries sometimes leak caustic chemicals that can damage the remote. If changing the battery doesn't solve the issue, there may be other issues that require professional attention.

Examine for evidence of rust, or other indications that the buttons are damaged or worn out. For instance, conductive paint may be missing. Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that has worn out or has conductive paint missing. Avoid rubbing too hard, since this could cause damage to the conductive paint and stop the button from firing when it is pressed.
Check the battery connector's terminals for loose solder connections. Soldering them back in place will restore the button's functionality if this is the case. The same method can be used to restore functionality to any other loose connections within the fob.
If any of the rubber buttons located at the front of the keyfob aren't working or require being pressing very hard the graphite disks at the back of the button could have worn out and will require replacement. This can usually be done by rubbing a pencil on the disks. This should bring the button back to working.
