When you hit a button on the key fob, it transmits an encoded code to the receiver, which then responds by performing the desired function. Commercial building owners also utilize key fobs because they can connect them to an entire system of access control. They can track who is entering and leaving and also stop fobs that were lost or stolen. As with any other electronic device key fobs are susceptible to failure periodically.

Utilizing a technique known as "replay attack," thieves can make use of the transmitter on the key fob to send a message that is recorded by the car's receiver.

Certain car manufacturers have an onboard program specifically designed for them for their vehicles, while others require you have an advanced programmer attached to the OBD2 connector. The most popular method to program new car keys is to place the key fob into the ignition and then turning it on several times in a specific sequence. This puts the car into the "programming mode," and once it is, one or more fob buttons are pressed to transmit the digital identification code to the car's computer. The computer then saves the code and then removes the car from programming mode. Certain manufacturers require that you have a special programer to program key fobs. These are costly and are difficult to use for the common person. Therefore, it is generally better to let a professional locksmith or dealer do the job for you. To begin the process of programming the new keyless entry car key, you must enter your vehicle from the driver's side, and close all the doors EXCEPT for the driver's door. This will prevent the system from locking the doors while you're trying to program the key. Push and hold the button on the fob you want to activate while the ignition is on and the other keys you want programmed are close by. The danger light will flash twice.
