If replacing the battery does not solve the issue there could be other issues that require professional attention. For instance, if the buttons appear stuck or broken it could be necessary to disassemble the remote and rework its parts. You could also try reprogramming the vehicle to recognize the new key fob.

Look for signs of rust or other indications that the buttons are damaged or worn out. For instance, conductive paint may be missing. Utilizing a Q-tip dipped in rubbing alcohol, gently clean any membrane contacts that are worn or have conductive paint missing. Don't rub too hard in order to damage the conductive paint and prevent the button from firing when it is pressed.
Check the battery connector's terminals carefully for any loose solder connections. If this is the case, simply reconnecting them could bring back function to the button. The same method can be used to restore function to any loose connections inside the fob.
If any of the rubber buttons located at the front of the keyfob aren't working or need to be pressed extremely hard the graphite disks at the back of the button may have worn out and need to replaced. car keys repair can usually be done by rubbing a pencil across the disks, which should bring the button back to working.
If none of this is helpful or if the button does not respond to a hard press, then it may be because the circuit board is damaged. It is possible to fix the issue by cleaning and re-soldering the button however, you should have a spare in case it doesn't work.

Non-Remote Transponder Chips
The non-remote chips sealed in a sealed case are more durable than remote fobs. However, they can be cracked in the event of a hole being drilled in them, or in the event that a door handle of a car or lawnmowers is pushed over them. Fuse failures are usually to blame for non-remote chip failures.
If you're handy enough to open the sealed key fob and can tolerate the mess, you can remove the circuit board and check the fuse with a multimeter to ensure that it is functioning as intended. function. If you're not comfortable with this, you can go to your local Oreilly or hardware store and use their RF frequency tester. This will let you know whether the key fob transmits an RF signal.
