Battery

You can consult the owner's manual or contact the manufacturer to find out the correct type. It is also essential to examine the battery compartment as dead batteries can leak caustic chemicals which can damage the remote. If replacing the batteries doesn't solve the problem it could be because there are other issues that require professional attention.

First, check that the batteries are up correctly and that the indentation on the back of the button is filled. Then, carefully open the remote and examine the circuit board. Examine for evidence of rust, or other indications that the buttons have been worn or damaged. For example, conductive paint may be missing. Then, using the Q-tip, dipped in alcohol to gently clean any membrane contacts that have worn or where conductive paint is missing. Don't rub too hard, as this could erode the conductive paint and prevent the button from firing when you press it.
Also, make sure to inspect the battery connector's terminals to ensure any loose solder connections. If this is the case, reconnecting them can restore function to the button. You can use the same process to restore functionality to any other loose connection inside the fob.
If any of the rubber buttons on the front of the keyfob isn't functioning or require to be press extremely hard the graphite disks at the back of the button might have worn out and require replacement. You can do this by rubbing a pen over the disks. This should bring the button back to life.
If none of this is useful or if the button still doesn't respond to a firm press, then it may be that the circuit board itself has become damaged.

It's also worth examining the battery terminal connections. If they are loose, the buttons could not work or even become stuck in their down position. Soldering the terminals back to their proper positions is usually enough to restore a non-working fob to a working condition.
Non-Remote Transponder Chips
Sealed non-remote transponder chip are more durable than remote fobs that have them but they can still be damaged by a hole that is drilled into them or run over by a lawnmowers blade or door handle for a car. Most of the time, non-remote transponder chips fail, and this could be attributed to an exploded fuse.
If you're not confident opening the key fob, remove the circuitboard and utilize a multimeter to check that the diode is functioning properly. If you don't feel comfortable with this, you can visit your local Oreilly or hardware store and use their RF frequency tester. This will tell you whether the key fob transmits signals.
Programming

They may lose their connection with the receiver inside your vehicle due to shocks or a low-battery, which requires changing the program. A professional auto key repair near me locksmith, or main dealer can reprogram the key fob and get it back functioning again. If, in the unlikely event that resetting and repairing your key fob fails it could be the time to replace it completely.
