Battery

If changing the batteries doesn't solve the issue it could be that there are other issues that require attention by a professional. For instance, if the buttons appear stuck or damaged it could be necessary to disassemble the remote and rework its parts. You can also try reprogramming your vehicle to recognize the new key fob.
Buttons
Key fobs can become dirty and worn-out from frequent use. This is not atypical however it can cause buttons to stop functioning or require a long press to work. This can be frustrating particularly when you're away from home and have to turn on your car. Even broken or damaged buttons are often fixable with a little time and materials you already have at home.
First, ensure that the batteries are charged correctly and that the indentation on the back of the button is filled. Then, open the remote with care and examine the circuit board. Examine for indications of rust or other indications that the buttons have been damaged or worn. For example there could be conductive paint missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that has become worn out or where conductive paint is missing. Don't rub too hard as this can damage the conductive paint, and block the button from firing when you press it.
Check the battery connector's terminals for loose solder connections. If this is the case, soldering them back in place could restore functionality to the button. The same process can be used to restore function to any other loose connections inside the fob.
If any of the rubber buttons located at the front of the keyfob are not functioning or require to be pressed very hard, the graphite disks at the back of the button could have worn out and require replacement. It is usually done by rubbing a pencil over the disks. This will bring the button back to life.

Water can also damage pins and connectors that are small on the board called via's.
If you're skilled enough to open your key fob and you don't mind making an mess, you can take the buttons out of their sockets and put in new ones. Also, it's worth checking the connections between battery terminals. They can become very dirty and if they're loose, the buttons may not work or even stay in their down position. Soldering the terminals back to their proper positions is usually enough to bring a non-working fob to a working condition.
Non-Remote Transponder Chips
The sealed non-remote chips are more durable than their remote fobs. However, they are susceptible to cracking if a hole is drilled into them or when a door handle for a car or lawnmowers plows over them. The failure of the fuse is usually to blame for non-remote chip failures.
If you're not comfortable opening the key fob, remove the circuitboard and use a multimeter to check that the diode is functioning properly. If you're not comfortable with this, go to your local Oreilly or hardware store and use their RF frequency tester. This will inform you whether the key fob sends signals.
