The way a keyless entry system operates is by sending radio signals and then looking for a response signal from the key fob. If the system recognizes the signal, the car's doors are opened and the computer on board is activated. Certain systems have a second receiver on the trunk of the car, which opens automatically when you put your foot on it.
Each key fob has an unique digital identity code that's given by the manufacturer. The fob is programmed with an exclusive process known as "programming". This involves turning on the ignition of the car repeatedly in a predetermined sequence, and may also require pulling levers or buttons or removing the fuse.

To help combat this issue, the majority of keyless entry systems rely on a method called rolling code that guarantees that each new transmitter signal received by the vehicle has a different counter than the previous one.
Batteries
A dead battery is the most common reason for a car remote to not work. It's a simple and inexpensive fix if you have a spare key fob on your desk to replace the old one with.

Buttons
