How to Fix a Key Fob That isn't Working

If your key fob isn't functioning There are a few simple steps that can fix it. First, ensure that it's not the backup remote.

If your backup remote is unable to unlock and lock the doors of your car, then it is most likely that the primary remote is not working. Most car remote key failures result from circuitry or battery problems.

Battery

The battery in the key fob could wear out over time. It is easy to replace batteries. However, it is important that you use the correct type. sneak a peek at these guys can check the owner's manual or contact the manufacturer to inquire about the right type. It is also a good idea to inspect the battery compartment with care because dead batteries can leak harmful chemicals that can cause damage to the remote. If changing the battery doesn't fix the issue there may be additional issues that require professional attention. For instance, if the buttons seem stuck or damaged it could be necessary to take the remote apart and rework its parts. It is also possible to reprogramme the vehicle to recognize the new device.

Buttons

From frequent use, key fobs can get dirty and worn. This is not uncommon, but it can cause buttons to cease working or require a very hard press for them to function. This can be very frustrating especially when you're away from home and have to turn on your car. Even worn-out or malfunctioning buttons are often fixable with a bit of time and materials you already have at home.

First, make sure the batteries are properly charged and that the indentation on the back of the button is filled. Then, carefully remove the remote and examine the circuit board. Examine for indications of rust or other signs the buttons are damaged or worn. For instance the paint that conducts electricity could be missing. Use a Q-tip dipped in rubbing alcohol, gently clean any membrane contacts that have damaged or where conductive paint is missing. Don't rub too hard, as this could erode the conductive paint and prevent the button from firing when you press it.

Check the battery connector terminals carefully for any loose solder connections. Soldering them back into place will restore the button's functionality in the event that this is the situation. You can use the same procedure to restore functionality to any other loose connection in the fob.


If any of the rubber buttons on the front of the keyfob isn't functioning or require to be pressed very hard, the graphite disks at the back of the button could have worn out and require replacement. You can do this by rubbing a pen across the disks. This will bring the button back to life.

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

Circuitry

If the key fob buttons function the circuit board that is inside your remote may be dirty. This issue can be fixed through a thorough examination. Broken cases and water are the most common causes of boards that are dirty. 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 on the board.

If you're handy enough to open up your key fob and aren't afraid of making a mess, we can de-solder the buttons and then solder new ones in their place. It's also worth looking at the battery terminal connections. They can get very dirty and if they're loose the buttons might not function or even stay in their down position. Soldering the terminals and button's back into place is typically all it takes to restore a non-working key fob to working condition.

Non-Remote transponder chips

The non-remote chips that are sealed are more durable than their remote fobs, but they are susceptible to breaking if a hole is drilled into them or when a door handle for a car or lawnmowers is pushed over them. Failures of the fuse are typically to blame for non-remote chip failures.

If you're handy enough to remove the sealed key fob and are willing to put up with the mess, you can remove the circuit board and examine the fuse using an instrument to verify diode function. If you're not sure with this, visit your local Oreilly or hardware store and utilize their RF frequency tester. This will tell you whether the key fob is sending signals.

Programming

Key fobs aren't indestructible and can be damaged by a variety of factors. They can break their connection with the receiver inside your vehicle because of shocks or a low-battery, which requires the reprogramming. A professional auto locksmith or the main dealer, can reprogram your key fob and get it back functioning again. If resetting or repairing the keyfob is not working it is possible to replace it.
