How to Fix a Key Fob That isn't Working

If your key fob isn't working, a few easy steps can fix it. The first step is to make sure that it's not your backup remote.

If your backup remote cannot unlock and lock the doors of your car, then it is likely that the primary remote isn't working. Most problems with car remote keys are caused by battery or circuitry problems.

Battery

It is not unusual for the battery inside the car key fob to wear out. It is fairly easy to replace a battery, although it is essential to make sure that you use the right type and you can consult the owner's manual or talk to the dealer of the manufacturer to find out the kind of battery you require. It is also essential to examine the battery compartment as batteries that are not working properly can release toxic chemicals that could damage the remote. If changing the batteries does not solve the issue it could be because there are other issues that require professional attention. For example, if buttons appear stuck or broken, it may be necessary to take the remote apart and rework its components. You could also try reprogramming the vehicle to recognize the new key fob.

Buttons

Key fobs may become filthy and worn out due to repeated use. It is not unusual for buttons to stop working, or to require a hard press to get them working. This can be very frustrating particularly when you're away from your home and you need to start your car. Even broken or damaged buttons can be fixed with a bit of time and tools you already have at home.

First, check that the batteries are up correctly and that the indentation on the back of the button is filled. Take the remote apart and look over the circuit board. Examine for signs of rust or other signs the buttons have been worn or damaged. For example the paint that conducts electricity could be missing. Use key repair near me -tip dipped into rubbing alcohol to gently clean any membrane contact that is worn-out or where conductive paint is missing. Avoid rubbing too hard since this could cause damage to the conductive paint and block the button firing when pressed.

Also, be sure to check the battery connector's terminals to ensure an unattached solder connection. Soldering them back in place will allow the button to function again in the event that this is the case. The same method can be used to restore function to any other loose connections inside the fob.

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

If none of these solutions work, or if you still cannot get the button to respond when pressed hard, it could be that the circuitry is failing. It is possible to fix this by cleaning and re-soldering the button, but you should have a spare in case it does not work.

Circuitry

The circuit board inside your remote control may be dirty regardless of whether the buttons on the key fob function or not. This problem can be resolved through a thorough examination. The most common causes for dirty circuit boards are water and damaged cases. A damaged case can allow water and other debris to get into the circuit board, which can cause it to short. Water can also eat away at pins and connectors that are small on the board, which are known as via's.

If you're skilled enough to open your key fob, and don't mind making an mess, you can take the buttons out of their sockets and solder in new ones. Also, you should check the connections between the battery terminals. They can become extremely filthy and if they're not tight enough, the buttons may not work or may even remain in their down position. Soldering terminals and buttons back to their proper positions is usually enough to bring a non-working fob back to working.

Non-Remote Transponder Chips


The non-remote chips that are sealed are more durable than remote fobs, but they can be cracked in the event of a hole being drilled in them or if a car door handle or lawnmowers is pushed over them. The majority of non-remote transponder chip malfunctions can be attributed to an exploded fuse.

If you are not comfortable opening the key fob, take the circuit board off and use a multimeter to check that the diode is operating properly. If you're not comfortable with this, you can go to your local Oreilly or hardware store and use their RF frequency tester. Suggested Internet page will inform you whether the key fob sends an RF signal.

Programming

Key fobs aren't indestructible and are susceptible to damage through a variety of causes. They can lose their pairing to the car's receiver due to shock or a low battery, which requires them to be reprogrammed. A professional auto locksmith or a main dealer will be able to reprogram your key fob and get it working again. If resetting or replacing the keyfob is not working it is possible to replace it.
