Battery

It is not uncommon to find a battery on the key fob for cars to wear out. It is easy to replace a battery. However it is crucial that you choose the right type. You can check the owner's manual or contact the manufacturer to inquire about the right kind. It is also crucial to examine the battery compartment, as dead batteries can leak caustic chemicals which can damage the remote. If changing the batteries doesn't solve the problem, it may be that there are other issues that require professional attention. If the buttons are broken or stuck, for example it might be necessary to take the remote apart and rework each component. It is also possible to reprogramme the vehicle to recognize the new fob.

Buttons

Key fobs may become filthy and worn out due to frequent use. This is not atypical however, it can cause buttons to cease functioning or require a difficult press to get them to function. This can be frustrating particularly when you're away from your home and need to switch on your car. Fortunately, even worn-out or damaged buttons can be fixed with a little time and a few materials you have in the house.

First, check that the batteries are properly placed and that the indentation on the back of the button has been filled. Then, open the remote with care and look over the circuit board. Look for indications of rust or other indications that the buttons have been damaged or worn out. For example there could be conductive paint missing. Use a Q-tip that has been dipped in alcohol to gently clean any membrane contact that has worn out or has conductive paint missing. Do not rub too vigorously, as this could erode the conductive paint and stop the button from firing when pressed.

Also, make sure to inspect the battery connector terminals for an unattached solder connection. If this is the case, simply soldering them back in place may bring back function to the button. The same process can be used to restore functionality to any other loose connections within the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob aren't working or require a difficult press to function, it is likely that the graphite disks on the back of the button are wearing down and require replacement. You can do this by rubbing a pen over the disks. This should bring the button to life.

Water can also eat away at pins and connectors that are small on the board called via's.

If you are handy enough to open your key fob and aren't afraid of making an mess, you can take the buttons out of their sockets and then solder new ones. It's also worth checking the connections between the battery terminals. If they're loose, the buttons could not function properly or become stuck 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 non-remote key repair chips that are sealed are more durable than their remote fobs. However, they can be cracked in the event of a hole being drilled into them or when a door handle for a car or lawnmowers is pushed over them. Most of the time non-remote transponder chip malfunctions can be blamed on blowing fuses.

If you are not comfortable opening the key fob, you may remove the circuitboard and utilize a multimeter to verify that the diode is operating properly. If you're not sure with this, visit your local Oreilly or hardware store and test their RF frequency tester. This will let you know whether the key fob transmits a signal.

They may lose their connection to the receiver in your car due to shock or low battery, which requires the reprogramming. A professional auto locksmith or main dealer can reprogram your key fob and get it back up and running. If resetting or replacing the keyfob is not working it is possible to replace it.
