Most keyless car remote fobs open by the small slot on the side, and inside, there is a small coin battery. When the keyless entry stops working, the first thing to check is the battery. The individual must check the old battery to get the battery size, and then buy a replacement. If the keyless entry fob doesn't work after that, the individual must check the memory.

A loss of memory often occurs with a faulty battery in a keyless car remote fob, but it is easy to repair. In most cases, an individual can repair this by entering the vehicle, closing the doors, and reprogramming the remote by entering the key into the ignition. Instead of starting the car, however, the individual must flip the key back and forth rapidly between the first and second settings. A chime indicates the first part of programming is complete. Next, the individual must press one of the remote buttons and then wait for a second chime noise.

If these do not work, it may be an issue with the car, and the individual must take the car to a professional for diagnosis.
