What's The Ugly Truth About Remote Key Repair
How to Fix a Key Fob That isn't Working

If your key fob won't work and you're not sure why, you can fix it by following some simple steps. First, ensure that it's not your backup remote.

If the backup can lock and unlock your car doors then there is likely an issue with the primary remote. The majority of car remote key malfunctions result from circuitry or battery problems.

Battery

The battery in the key fob may wear out over time. It is easy to replace a battery. However, it is important that you choose the right kind. You can refer to your owner's manual or call the manufacturer to inquire about the correct type. It is also a good idea to inspect the battery compartment with care because dead batteries can release caustic chemicals that could damage the remote. If replacing the battery does not solve the issue there could be other issues that require attention from a professional. For example, if buttons seem stuck or broken it could be necessary to take the remote apart and rebuild its components. You could also try reprogramming the vehicle to recognize the new key fob.

Buttons

Key fobs can get dirty and worn out from repeated use. This is not atypical, but it can cause buttons to stop functioning or require a hard press for them to function. This can be a huge hassle especially if you're away from home and need to start your vehicle. Even malfunctioning or worn-out buttons are often fixable with a little time and tools you already have at home.

First, verify 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 inspect the circuit board. Examine for indications of rust or other signs the buttons are worn or damaged. For example there could be conductive paint missing. Use a Q-tip dipped in alcohol, gently clean any membrane contacts that have worn or where conductive paint is missing. Be careful not to rub too hard, because this could damage the conductive paint and stop the button from firing when it is it is pressed.

Also, make sure to inspect the battery connector's terminals for an unattached solder connection. If this is the case, reconnecting them could restore function to the button. The same process can be used to restore function to any loose connections inside the fob.

If any of the rubber buttons on the front of the keyfob isn't functioning or require to be pressing very hard the graphite disks on the back of the button might have worn out and require replacement. This can usually be done by rubbing a pencil over the disks. This should bring the button back to working.


If sneak a peek at this web-site of this doesn't help, or if the button does not respond to a hard push, then it may be because the circuit board itself has gone bad. It is possible to fix this issue by cleaning and re-soldering the button however, you should have a spare in case it doesn't work.

Circuitry

The circuit board in your remote control may be dirty, regardless of whether the buttons on the key fob are working or not. A thorough examination will usually resolve this issue. Broken and damaged cases are the most frequent causes of dirty boards. A damaged case can allow water and other debris to pass through and short out the electronic components. Water can also eat through pins and vias, which are the tiny connectors that are found on the board.

If you're able to remove your key fob, and you're not afraid of a little mess, we can remove the solder from the buttons and put new ones in their place. It's also worth checking the battery terminal connections. They can become extremely dirty and if they're loose the buttons might not work or even stick in their down position. Soldering terminals and buttons back to their original positions is often enough to return a malfunctioning fob to a working condition.

Non-Remote transponder chips

The sealed non-remote chips are more durable than their remote fobs, but they are susceptible to breaking when a hole is made into them or if a car door handle or lawnmowers is pushed over them. Fuse failures are usually the cause of non-remote chip failures.

If you're not comfortable opening the key fob, you may take the circuit board off and use a multimeter to check that the diode is working properly. If you don't feel comfortable with this, you can visit your local Oreilly or hardware store and test their RF frequency tester. This will let you know whether the key fob transmits signals.

Programming

Key fobs take many abuses and aren't impervious to damage. They can lose their pairing with the receiver inside your vehicle due to shocks or a low battery, requiring changing the program. A professional auto locksmith or dealer can reprogram your key fob and get it working again. If resetting or repairing the keyfob is not working it is possible to replace it.
