It's recommended to examine the battery compartment thoroughly because dead batteries can leak harmful chemicals that can cause damage to the remote. If replacing the battery does not solve the issue, there may be other issues requiring professional attention. If buttons are stuck or broken for instance, it may be necessary remove the remote and rebuild each component. It is also possible to reprogramme the vehicle to recognize the new device.

Look for signs of rust or other indications that the buttons have been worn or damaged. For example the paint that conducts electricity could be missing. Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that is worn out or where conductive paint is missing. Avoid rubbing too hard, as this can erode the conductive paint and block the button from firing when it is pressed.
Also, make sure to inspect the battery connector's terminals to ensure any loose solder connections. If this is the case, soldering them back in place may restore functionality to the button. You can use the same method to restore functionality to any other loose connection in the fob.
If any of the rubber buttons located at the front of the keyfob are not functioning or require to be pressing extremely hard, the graphite disks at the back of the button could have worn out and will require replacement. You can usually do this by rubbing a pen over the disks. This will bring the button back to life.
If none of this is helpful, or if the button doesn't respond to a firm press, then it may be that the circuit board itself is damaged. This can sometimes be repaired with a quick clean and re-soldering, but it is ideal to have a spare fob available in the event this method fails for you.

Also, you should check the connections between the battery terminals. If they're loose, the buttons might not function properly or become stuck in their down position. Soldering the terminals and buttons to their original positions is often enough to bring a non-working fob to working.
Non-Remote transponder chips
The sealed non-remote chips are more durable than remote fobs. However, they are susceptible to cracking if a hole is drilled in them, or if a car door handle or lawnmowers plows over them. Most of the time, non-remote transponder chips fail, and this could be attributed to an exploded fuse.
If you're able to open up a sealed non-remote key fob and can tolerate the mess, you can take off the circuit board and check the fuse with an instrument to verify diode function. If you're unsure about doing this, go to your local hardware store or the Oreilly's and they usually have an RFID frequency tester that can let you know if the key fob is sending signals.
