Solutions To The Problems Of Remote Key Repair

How to Fix a Key Fob That isn't Working

If your key fob won't work, you can fix it with some simple steps. The first step is to make sure that it's not the backup remote.

If the backup remote is able to lock and unlock your car key and repair doors then there is likely an issue with the primary remote. Most car remote key failures result from battery or key repair car circuitry problems.

Battery

The battery inside the Key repair Car fob could be worn out over time. It is relatively easy to replace the battery, however it is crucial to make sure that you select the correct one; you can look in the owner's manual or talk to the manufacturer's dealer to determine the type of battery you require. It is also essential to check the battery compartment as dead batteries can leak caustic chemicals which can damage the remote. If changing the batteries does not solve the problem it could be that there are other issues that require attention from a professional. If the buttons are stuck or broken, for example it might be necessary to remove the remote and rebuild each component. You could also try reprogramming the vehicle to recognize the new fob.

Buttons

Key fobs may become dirty and worn out from frequent use. This is not unusual however, it can cause buttons to stop working or require a very difficult press to get them to function. This can be very frustrating particularly if you're out of town and need to start your car. Even worn-out or malfunctioning buttons can be fixed with a bit of time and the tools you already have at home.

First, make sure the batteries are charged correctly and that the indentation on the back of the button is filled. Then, carefully open up the remote and look at the circuit board. Check for signs of rust or other indications that the buttons have been worn or damaged. For example the paint that conducts electricity could be missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that has become damaged or where conductive paint is missing. Avoid rubbing too hard, since this could cause damage to the conductive paint and block the button from firing when pressed.

Also, be sure to check the battery connector terminals for an unattached solder connection. If this is the case, simply connecting them back may restore function to the button. The same procedure can be used to restore function to any loose connections in the fob.

In the end, if any of the buttons made of rubber that are on the front of the key fob have stopped functioning or require a long press to function it is likely that the graphite disks that are on the back of the button are wearing out and need to be replaced. This is usually done by rubbing a pencil over the disks, which should bring the button back to its original state.

If none of this is helpful, or if the button doesn't respond to a hard push It could be that the circuit board itself is damaged. This can sometimes be repaired with a quick clean and refitting, but it's best to have an extra fob on hand in the event that this method does not work for you.

Circuitry

Whether or not the key fob buttons function, the circuit board inside your remote might be dirty. A thorough examination is usually enough to fix this issue. Broken cases and key repair car water are the most frequent causes of boards that are dirty. A damaged case allows water and other debris to get in and short circuit the electronics. Water can also damage pins and vias, which are tiny connectors on the board.

If you're able to open your key fob, and you're not afraid of making a mess, we can take off the buttons and solder new ones in their place. It's also worth checking the connections between the battery terminals. If they're loose, the buttons might not work or even become stuck in their down position. Soldering terminals and buttons back to their original positions is often enough to restore a non-working fob to working.

Non-Remote transponder chips

The sealed non-remote chips are more durable than remote fobs. However, they are susceptible to breaking in the event of a hole being drilled in them or in the event that a door handle of a car or lawnmower runs over them. Most of the time, non-remote transponder chip failures can be attributed to a blown fuse.

If you're able to remove the sealed key fob and can tolerate the mess, you can easily remove the circuit board and check the fuse with an instrument to verify diode function. If you're not confident doing this, go to your local hardware store or Oreilly's, and they usually have a radio frequency tester that can let you know if the key fob is sending signals.

Programming

Key fobs aren't impervious to destruction and are susceptible to damage by a lot of things. They can lose their pairing to the car's receiver due to shock or a low battery, requiring the reprogramming. A professional auto locksmith, or a dealer in the main, can reprogram your keyfob and get it working again. If resetting or replacing your key fob fails it is possible to replace it.
