How to Fix a Key Fob That isn't Working

If your key fob isn't working, a few easy steps can be taken to fix it. First, make sure that it's not the backup remote.

If your backup remote is unable to unlock and lock the doors of your car, it is likely that the primary remote isn't working. The most common causes for key malfunctions for car remote key repair remotes are circuitry or battery issues.

Battery

The battery in the key fob may get worn out over the course of time. It is relatively easy to replace the battery, however it is crucial to ensure you choose the correct type and you can consult your owner's manual, or contact the manufacturer's dealer to determine the type of battery you require. It is recommended to inspect the battery compartment with care because dead batteries can release caustic chemicals that could harm the remote car key repair car keys near me near me; clicking here,. If replacing the batteries doesn't solve the problem it could be because there are other issues that require professional attention. If the buttons are stuck or broken for instance, it may be necessary disassemble the remote and rework each component. You can also try reprogramming your vehicle to recognize the new key fob.

Buttons

Key fobs can get filthy and worn out due to repeated use. It is not uncommon to have buttons stop functioning, or require a long push to make them work. This can be frustrating especially when you're away from home and have to start your car. Even broken or damaged buttons can be fixed with a bit of time and the tools you already have at home.

First, make sure that the batteries are correctly installed and that the indentation on the back of the button is filled. Then, carefully remove the remote and look at the circuit board. Look for signs of corrosion or other signs that buttons are worn out or damaged, such as missing the conductive paint. Use a Q-tip that has been dipped in alcohol to gently clean any membrane contact that has become worn-out or where conductive painting is missing. Don't rub too hard as this can damage the conductive paint, and block the button from firing when pressed.

Check the battery connector terminals for loose solder connections. If this is the case, simply reconnecting them could bring back function to the button. The same process can be used to restore functionality to any other loose connections within the fob.

If any of the rubber buttons located at the front of the keyfob isn't working or need to be pressing very hard the graphite disks at the back of the button may have worn out and require replacement. You can usually do this by rubbing a pencil over the disks. This should bring the button to life.

If none of these solutions work, or if you still cannot get the button to respond when pressed hard, it is possible that the circuitry has failed. It is possible to fix the issue by cleaning and re-soldering the fob, but you should have a spare in case it doesn't work.

Circuitry

The circuit board of your remote control may be dirty, regardless of whether the buttons on the key fob work or not. A thorough inspection is usually enough to fix this issue. The most common causes of dirty circuit boards are water and damaged cases. A broken case allows water and other debris to enter and short circuit the electronics. Water can also get through pins and vias, which are small connectors found on the board.

If you're handy enough to open your key fob, and you're not afraid of making a mess, we can remove the solder from the buttons and put new ones in their place. It's also worth checking the connections between the battery terminals. They can get very filthy and if they're not tight enough, the buttons might not work or may even remain in their down position. Soldering the terminals, and putting the button back into place is typically all it takes to restore the automotive key repair fob that is not working to working condition.

Non-Remote Transponder Chips

The sealed non-remote chips are more durable than remote fobs, but they are susceptible to breaking when a hole is made in them or if a car door handle or lawnmowers is pushed over them. Most of the time, non-remote transponder chip failures could be attributed to blowing fuses.

If you are not comfortable opening the key fob, remove the circuitboard 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 inform you whether the key fob transmits signals.

Programming

Key fobs are subject to many abuses and aren't completely indestructible. They can lose their pairing with the receiver in your vehicle due to shocks or low battery, which calls for the reprogramming. A professional auto locksmith, or a dealer in the main can reprogram the key fob and get it back working again. If resetting or repairing your key fob fails, you may need to replace it.
