How to Fix a Key Fob That isn't Working<br /><br />If your key fob does not work then you can fix it by following just a few steps. First, ensure that it's not the backup remote.<br /><br />If your backup remote is unable to lock and unlock the doors of your vehicle, it is most likely that the primary remote isn't functioning. The majority of car remote key malfunctions are caused by circuitry or battery problems.<br /><br />Battery<br /><br />The battery inside the key fob may get worn out over the course of time. It is simple to replace batteries. However it is crucial that you choose the right kind. You can consult your owner's guide or contact the manufacturer to determine the right kind. It is recommended to inspect the battery compartment carefully, as dead batteries sometimes leak harmful chemicals that can harm the remote. If replacing the batteries doesn't solve the issue it could be because there are other issues that require attention from a professional. If buttons are damaged or stuck for instance it could be necessary to disassemble the remote and rework each component. You could also try reprogramming the vehicle to recognize the new fob.<br /><br />Buttons<br /><br />Key fobs may become dirty and worn-out from frequent use. This is not unusual however, it can cause buttons to cease working or require a very hard press for them to work. This can be a hassle, especially when you are away from home and you need to start your car. Even worn-out or malfunctioning buttons are often fixable with a little effort and tools you already have at home.<br /><br />First, check that the batteries are correctly installed and that the indentation at the back of the button has been filled. Then, carefully open up the remote and look at the circuit board. Look for signs of corrosion or other indications that the buttons are worn out or damaged, like missing the conductive paint. Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that has become worn out or where conductive paint is missing. Be careful not to rub too hard, because this could damage the conductive paint and stop the button firing when pressed.<br /><br />Examine the battery connector's terminals for loose solder connections. Soldering them back in place can restore the button's functionality If this is the situation. <a href="https://www.g28carkeys.co.uk/car-key-repairs-near-me/">repair broken car key</a> can be used to restore functionality to any other loose connections within the fob.<br /><br />If, for instance, any of the buttons made of rubber on the front of the key fob aren't working or require a hard press to work it is likely that the graphite disks on the back of the button are wearing out and require replacement. It is usually done by rubbing a pen across the disks. This should bring the button to life.<br /><br />If none of this is useful or if the button doesn't respond to a firm press It could be because the circuit board is damaged. It is possible to fix this by cleaning and re-soldering the fob but you should also have another spare in case it does not work.<br /><br />Circuitry<br /><br />The circuit board in your remote control could be dirty, regardless of whether the buttons on the key fob are working or not. A very thorough inspection is often enough to resolve this problem. Broken and damaged cases are the most common causes of boards that are dirty. A broken case allows water and other debris to enter and short circuit the electronic components. Water can also eat away at pins and connectors that are small on the board, which are known as via's.<br /><br />If you're handy enough to remove your key fob and aren't afraid of some mess, we can remove the solder from the buttons and solder new ones in their place. Also, you should check the connections between the battery terminals. They can become extremely dirty and if they're loose the buttons might not function or may even remain in their down position. Soldering the terminals and buttons into place is usually enough to restore a non-working fob back to working.<br /><br />Non-Remote Transponder Chips<br /><br />Sealed non-remote transponder chip are more durable than the remote fobs that have them but they can still be broken by a hole being drilled into them or run over by a lawnmowers blade or door handle for a car. The failure of the fuse is usually to blame for non-remote chip failures.<br /><br />If you are not comfortable opening the key fob, you may remove the circuitboard and utilize a multimeter to determine if the diode is working correctly. If you don't feel comfortable with this, you can visit your local Oreilly or hardware store and utilize their RF frequency tester. This will let you know whether the key fob sends signals.<br /><br /><br /><br />Programming<br /><br />Key fobs take a lot of abuse and aren't indestructible. They can lose their pairing with the receiver inside your vehicle because of shocks or a low-battery, which requires reprogramming. A professional auto locksmith or dealer can reprogram your key fob and get it functioning again. If resetting or fixing your key fob fails, you may need to replace it.<br /><br />
