Remote Key Fob Repair Modern vehicles are equipped with the remote key fob which can be used to lock, unlock or start the car. As with any high-tech piece equipment, there can be issues. Usually these are very simple to fix. You can reset it by following the instructions in your owner’s manual. Check the Battery The battery inside the fob that powers it is responsible for the remote control function. It's a small, inexpensive part that needs to be replaced frequently to ensure the fob's functionality. There are many other reasons your key fob may not be functioning, aside from the battery. This could be due to physical damage, water exposure, or internal component failure. Whatever the reason the key fob isn't responding, it's time to replace the battery. Make sure you have the right size battery. The majority of modern key fobs are powered by a CR2032 three-volt battery which is easily found in many stores. The majority of these batteries are stamped with the size on one of the fob's edges. A quick search for the name of your vehicle's brand should help you find the exact type of battery it takes. Open your key fob carefully and take out the original battery. Take a picture of the inside of your fob to ensure you put it back in the correct way. This simple step can save you from buying another fob if you made an error when making it back together. Some key fobs also have a mechanical backup key known as an emergency blade. This is found inside the key fob and allows you to open your car's driver's side door in case the remote control fails to function. To open the blade of the key, you must locate the notch that lies in the middle of your fob. The notch is typically an oval shape that is hidden by the plastic casing of the fob. If you want to check the battery's voltage using extra care, you can make use of a multimeter. The majority of modern key fobs have built-in voltmeters, but you can buy a multimeter from many hardware stores for a few bucks. In general, the battery should read 3.0 volts or more. A reading below that level could indicate a battery that is in its final stages and must be replaced immediately.

It isn't unusual for these remotes to fail after a certain time, especially if the vehicle is used frequently or if there is lots of physical abuse associated with it.

The majority of modern car key fobs have several buttons that can be used for various purposes like locking and unlocking the doors as well as activating the panic button, as well as opening the trunk.

The buttons on a key fob reset by snapping it apart and checking that they're not broken or stuck. Key fobs aren't typically made to be removed however, the battery connector terminals on a key fob may become loose as time passes. If the buttons' contacts are disconnected from the circuit board, a simple solder job could be enough to get them back on track and allow the fob back to full functionality. If a fob gets damaged or dropped, the buttons could be damaged, misaligned or out of alignment.
