You can consult your owner's guide or contact the manufacturer to determine the right kind. It is also essential to examine the battery compartment as batteries that are not working properly can release caustic chemicals that can harm the remote. If replacing the battery does not solve the issue, there may be other issues requiring professional attention. For instance, if the buttons seem stuck or damaged, it may be necessary to disassemble the remote and rebuild its components. You can also try reprogramming your car to recognize the new key fob.
Buttons
From frequent use, key fobs can wear out and become dirty. It is not unusual for buttons to cease working, or to require a hefty press to make them work. This can be a huge hassle, especially if you are out of town and need to start your vehicle. Even broken or damaged buttons are often fixable with a bit of time and tools you already have at home.
First, ensure that the batteries are up correctly and that the indentation on the back of the button is filled. Open the remote carefully and examine the circuit board. Examine for signs of rust or other signs that buttons are worn out or damaged, such as missing conductive paint. Use a Q-tip, dipped in alcohol to gently clean any membrane contact that is damaged or where conductive paint is missing. Be careful not to rub too hard, since this could cause damage to the conductive paint and block the button from firing when it is pressed.
Also, carefully check the battery connector's terminals for any loose solder connections. If this is the case, reconnecting them can restore functionality 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 isn't working or need to be pressing extremely hard, the graphite disks at the back of the button might have worn out and will need to replaced. You can usually do this by rubbing a pencil over the disks. This will bring the button back to life.
If none of these solutions work, or if you still are unable to get the button to respond when you press it hard, it is possible that the circuitry is failing. This can be fixed by a quick clean and re-soldering, but it is ideal to have a spare fob available in the event this method doesn't work for you.

It's also worth checking the connections between battery terminals. They can get very filthy and if they're not tight enough, the buttons might not work or even stay in their down position. Soldering the terminals and button's back in place is usually all that's needed to return a non-working key fob to working condition.
Non-Remote Transponder Chips
The non-remote chips sealed in a sealed case are more durable than remote fobs, but they are susceptible to cracking when a hole is made in them or in the event that a door handle of a car or lawnmowers plows over them. The majority of non-remote transponder chip malfunctions can be blamed on an exploded fuse.
If you're not confident opening the key fob, you can remove the circuitboard and utilize a multimeter to check that the diode is operating correctly. If you're not comfortable doing this, go to your local hardware store or Oreilly's, and they'll usually have an RF frequency tester that will tell you if the key fob is sending a signal.
Programming
