The key fob makes use of radio signals to communicate with a receiver in the vehicle. When you press the button on the keyfob it sends the code to the receiver which then does the job you want it to. Commercial building owners also use key fobs because they can connect them to an entire system of access control. They can monitor who enters and exits, and stop fobs that have been taken or lost.
Key fobs, like any other electronic device, may malfunction. Because they are constantly tossed around in pockets and purses, they can become damaged or lose their signal. While they can endure some abuse, they aren't indestructible. After all, they are made from plastic and metal.

Modern keyless entry systems use rolling code technology to guard against security breaches. It is important to keep in mind that even this technology is not 100% secure. A burglar could employ a technique referred to as "replay attack" to send a message that is recorded by the car's receiver. After the message has been recorded, a rogue device could retransmit the message to the vehicle receiver and gain access.
Depending on your vehicle's make and model it could be possible to program new keys on your own, or you may need to hire an automotive locksmith assist you.

The most popular method to program new car keys is by putting the key fob into the ignition and engaging it several times in a specific sequence. This puts the car into the "programming mode," and once it is activated, one or more fob buttons are depressed to transmit the digital identification code to the computer in the car. The computer then saves the code and takes the car out of programming mode.
Certain manufacturers require you to have a special advanced programmer to program key fobs, and some are expensive and difficult to use by a typical person. It's best to leave the task to an auto locksmith or dealer.
To begin the process of programming a new keyless entry vehicle key, enter your vehicle from the driver's side and shut all the doors EXCEPT for the driver's door.
