11 Methods To Redesign Completely Your Remote Key Repair
How to Fix a Key Fob That isn't Working

If your key fob does not work and you're not sure why, you can fix it by following just a few steps. The first step is to make sure it's not the backup remote.

If the backup remote is able to lock and unlock your car door, then there is likely an issue with the main remote. The majority of car remote key malfunctions result from circuitry or battery issues.

Battery

It is not unusual to find a battery on a key fob for cars to get worn out. It is easy to replace a battery. However, it is important that you choose the right type. You can check your owner's manual or call the manufacturer to determine the right type. It is recommended to inspect the battery compartment carefully since dead batteries may leak caustic chemicals that can cause damage to the remote. If changing the batteries does not solve the issue, it may be that there are other issues that require attention from a professional. For example, if buttons seem to be stuck or damaged, it may be necessary to disassemble the remote and rework its components. You can also try reprogramming the vehicle to recognize the new device.

Buttons

Key fobs can get dirty and worn-out from repeated use. It is not unusual for buttons to stop working, or to require a hefty push to make them work. This can be a huge hassle, especially if you are away from home and need to start your car. Even broken or damaged buttons can be fixed with a little effort and tools you already have at home.

First, ensure that read on are charged correctly and that the indentation on the back of the button is filled. Then, open the remote with care and look over the circuit board. Examine for signs of rust or other indications that the buttons are worn out or damaged, like missing conductive paint. Then, using the Q-tip, dipped in alcohol, gently clean any membrane contacts that have damaged or have conductive paint missing. Don't rub too hard in order to damage the conductive paint and stop the button from firing when it is pressed.

Also, carefully check the battery connector's terminals for any loose solder connections. If this is the case, connecting them back could restore functionality to the button. You can apply the same method to restore functionality to any other loose connection within the fob.

If any of the rubber buttons at the front of the keyfob are not functioning or require to be press extremely hard the graphite disks on the back of the button might have worn out and will need to replaced. You can usually do this by rubbing a pen over the disks. This should bring the button to life.

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

Circuitry

If the key fob buttons function the circuit board that is inside your remote might be dirty. This problem can be resolved by a thorough inspection. The most common causes for dirty circuit boards are water and damaged cases. A damaged case can allow water and other debris to enter and short out the electronics. Water can also destroy pins and small connectors on the board, which are known as via's.

If you're able to open your key fob and don't mind making a mess, we can take off the buttons and then solder new ones in their place. It's also worth examining the battery terminal connections. They can become very filthy and if they're not tight enough, the buttons may not work or even stay in their down position. Soldering the terminals and button's back in place is usually all it takes to restore a non-working key fob to working order.

Non-Remote transponder chips

Sealed non-remote transponder chips are more durable than remote fobs that have them but they can be damaged by a hole that is made in them or pushed over by a lawnmowers or door handle for a car. The majority of non-remote transponder chip malfunctions can be attributed to a blown fuse.

If you're not confident opening the key fob, you may remove the circuitboard and use a multimeter to check that the diode is functioning correctly. If you're not sure with this, you can visit your local Oreilly or hardware store and test their RF frequency tester. This will tell you whether the key fob sends a signal.

Programming


Key fobs are subject to many abuses and aren't indestructible. They may lose their connection with the receiver inside your vehicle due to shocks or a low battery, which calls for changing the program. A professional auto locksmith, or a dealer in the main, can reprogram your keyfob to get it up and running again. In the event that resetting and repairing your key fob isn't working, it could be time to replace it completely.
