10 Things You Learned From Kindergarden That'll Help You With Remote Key Repair
How to Fix a Key Fob That isn't Working

If your key fob won't work then you can fix it with just a few steps. The first step is to make sure it's not the backup remote.

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

Battery

It is not unusual for the battery in a car key fob to get worn out. It is simple to replace the battery. However, it is important to select the right kind. You can refer to your owner's manual or call the manufacturer to determine the right kind. It is also important to examine the battery compartment, as dead batteries can leak toxic chemicals that could damage the remote. If replacing the battery does not fix the problem there may be additional issues requiring professional attention. For car key repair , if buttons seem to be stuck or damaged It may be necessary to disassemble the remote and rebuild its components. You could also try reprogramming the vehicle to recognize the new device.

Buttons

Key fobs can become dirty and worn-out from frequent use. This is not uncommon, but it can cause buttons to stop functioning or require a long press to function. This can be frustrating particularly when you're away from home and you need to turn on your car. 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 correctly inserted and that the indentation at the back of the button has been filled. Then, open the remote with care and inspect the circuit board. Check for signs of corrosion or other signs that the buttons are worn or damaged, such as missing paint that is conductive. Use the Q-tip, dipped in alcohol, gently clean any membrane contacts that have worn or where conductive paint is missing. Don't rub too hard in order to damage the conductive paint and prevent the button from firing when pressed.

Check the battery connector's terminals carefully for any loose solder connections. Soldering them back into place can restore the button's functionality if this is the situation. The same method can be used to restore function to any other loose connections in the fob.


If, for instance, any of the buttons made of rubber on the front of the key fob have stopped functioning or require a long press to function it is likely that the graphite disks at the back of the button are wearing out and need to be replaced. This can be done by rubbing a pencil across the disks, which will bring the button back to working.

If all of this doesn't help, or if the button doesn't respond to a firm press It could be the case that the circuit board has gone bad. It is possible to fix this with a quick clean and refitting, but it's recommended to have an additional fob in case this method doesn't work for you.

Circuitry

If the key fob buttons are working the circuit board in your remote might be dirty. This problem can be resolved by a thorough inspection. Broken and damaged cases are the most frequent causes of boards that are dirty. A damaged case could allow water and other debris to enter the circuit board, causing it to short. Water can also eat through pins and vias, which are the tiny connectors found on the board.

If you're able to open your key fob and don't mind making a mess, we can de-solder the buttons and put new ones in their place. Also, it's worth checking the connections between the battery terminals. If they're loose, the buttons could not function or get stuck in their down position. Soldering the terminals and button's back in place is usually all that's required to return the key fob that is not working to working condition.

Non-Remote transponder chips

The non-remote chips sealed in a sealed case are more durable than remote fobs, however they are susceptible to breaking when a hole is made into them or in the event that a door handle of a car or lawnmower runs over them. Failures of the fuse are typically the cause of non-remote chip failures.

If you're handy enough to open a sealed non-remote key fob and are able to bear the mess, you can remove the circuit board and examine the fuse using an instrument to verify diode function. If you don't feel comfortable with this, you can visit your local Oreilly or hardware store and use their RF frequency tester. This will tell you whether the key fob sends a signal.

Programming

Key fobs take a lot of abuse and aren't completely indestructible. They may lose their connection with the receiver in your vehicle because of shocks or a low-battery, which requires the reprogramming. A professional auto locksmith or main dealer can reprogram the keyfob and get it working again. If resetting or replacing your keyfob does not work it is possible to replace it.
