How to Fix a Key Fob That isnt Working If your key fob isnt functioning a few easy steps can be taken to fix it The first step is to make sure that its not the backup remote If the backup can lock and unlock your car doors it is most likely an issue with the primary remote The most frequent causes of key problems with your car remote are issues with the circuitry or battery Battery It is not unusual for the battery inside a key fob for cars to wear out It is simple to replace the battery However it is important that you use the correct kind You can consult the owners manual or contact the manufacturer to determine the right kind It is recommended to inspect the battery compartment thoroughly since dead batteries may release caustic chemicals that could damage the remote If changing the battery doesnt fix the issue there could be other issues requiring professional attention For instance if the buttons seem to be stuck or broken 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 Key fobs can get dirty and wornout from frequent use It is not uncommon for buttons to cease working or to require a hefty press to get them working This can be very frustrating especially when youre away from your home and need to turn on your car Even malfunctioning or wornout buttons can be fixed with a bit of time and the tools you already have at home First verify that the batteries are properly installed and that the indentation at the back of the button is filled Take the remote apart and examine the circuit board Examine for signs of rust or other indications that the buttons have been worn or damaged For instance conductive paint may be missing Use a Qtip dipped into alcohol to gently clean any membrane contact that is wornout or where conductive painting is missing Avoid rubbing too hard as this can erode 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 Soldering them back into place will allow the button to function again in the event that this is the case repair keys near me can be used to restore function to any other loose connections inside the fob If for instance any of the rubber buttons on the front of the key fob stop functioning or require a hard press to work it is likely the graphite disks at the back of the button are wearing out and need to be replaced This is usually done by rubbing a pencil across the disks This should bring the button back to life If none of these solutions work or if you still not be able to get the button respond when you press it hard it could be that the circuitry is failing It is possible to fix this issue by cleaning and resoldering the button but you should have an extra in case it does not work Circuitry Whether or not the keys fob buttons are functioning the circuit board that is inside your remote might be dirty A thorough inspection will usually resolve this issue The most frequent causes of dirty circuit boards are water and broken cases A damaged case can allow water and other debris to get in and short circuit the electronic components Water can also get through pins and vias which are the tiny connectors that are found on the board If youre able to remove your key fob and dont mind some mess we can remove the solder from the buttons and put new ones in their place Also you should check the connections between battery terminals They can become very dirty and if theyre loose the buttons might not function or even stick in their down position Soldering the terminals back to their proper positions is usually enough to restore a nonworking fob to working NonRemote Transponder Chips Sealed nonremote transponder chip are more durable than the remote fobs they are contained in but they can be cracked by a hole made in them or pushed over by a lawnmower or door handle for a car The majority of nonremote transponder chips fail and this can be blamed on a blown fuse If youre handy enough to open a key fob that is sealed 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 dont feel comfortable with this go to your local Oreilly or hardware store and test their RF frequency tester This will inform you whether the key fob transmits signals Programming Key fobs take lots of abuse and arent impervious to damage They can lose their pairing with the receiver in your vehicle because of shocks or a low battery which calls for changing the program A professional auto locksmith or the main dealer can reprogram your key fob and get it back working again If resetting or fixing the keyfob is not working it may be necessary to replace it
