Broken Key Fobs Car key fobs are not indestructible, and like all electronic devices, they are prone to problems at some time. Fortunately, they're not that difficult to fix if they cease to function. You'll first need to determine the cause. Most of the time when the key fob stops working, it's because the battery is dead. The simplest and most economical solution is to replace the battery. It's possible to do this at your home. If replacing the battery doesn't work, try taking it apart and cleaning it. The circuit board of your fob contains “contact pads” that correspond to every button on the fob. (Lock buttons and trunk buttons for example.) The contact pads have a rubbery feeling and are covered with an electrically conducting film that wears off over time. You can clean the contacts on your key fob with cotton swab to remove any corrosion. If you suspect that your contacts are broken or loose If you suspect that the contacts are damaged or loose, you can use a pair tweezers. If you do this it's recommended to apply some silicone on the back of your key fob before inserting the new contacts. Silicone will seal the contacts to keep out water.

When you press a key fob, it sends the car a message that communicates to it what you're trying to do. If the key fob is not connected it will no longer recognize the vehicle, and will no longer allow you to start the engine. If you're unable to get your key fob back to be paired with the car, it's time to call in an auto locksmith or dealer technician. They will have the equipment required to reprogram the fob to make it work again. You'll likely have to pay a small amount for the service, but it's cheaper than purchasing an entirely new key fob. Keys that aren't responsive When the keyboard key isn't working, it could be an absolute nightmare. First, make sure that the key isn’t blocked by anything.

This can help you figure out if there is any problems with software or the keyboard itself. Another reason why a single key not performing its expected function is that the switch isn't working correctly. You can determine whether your keyboard is mechanical by looking underneath the keycap to determine whether there is any debris stuck.

This will let you replace the hooks that connect the retainer to the switch, and hopefully restore functionality to the key. If a key on your keyboard isn't performing the intended function in only one program, it's likely that the settings for the game's keyboard have assigned the key to a different action.

This is especially important in the case of a game that requires a lot of typing.
