The key fob communicates to the receiver in the vehicle using radio signals. When you press the key fob, it transmits an encoded code to the receiver, which in turn responds by performing the function you want. Commercial building owners also utilize key fobs as they allow them to connect them to an entire system of access control. They can track who is entering and leaving and also block fobs that have been stolen or lost.

Thieves could use a technique known as "replay attack" to send a message which is recorded by the receiver of the car. Once the message has been recorded, a rogue gadget can transmit the transmission again to the car's receiver in order to gain access.
Depending on the model and make of your vehicle, you may be able to program new keys yourself, or you may have to employ an automotive locksmith to do it. Some car manufacturers have a special onboard program and others require you have an advanced programer connected to the OBD2 connector.
The most common way to program new car keys is to place the key fob into the ignition and engaging it repeatedly in a certain order. This puts the car in a "programming mode," and once it is, one or more fob buttons are depressed to transmit the digital identification code to the car's computer. The computer then saves the code and removes the car from programming mode.
Certain manufacturers require you to have an advanced programer to program key fobs and some of these are expensive and difficult to use by a typical person. Therefore, it's best to let a professional locksmith or dealer do the job for you.
To begin programming for a car with keyless entry, enter your vehicle from the driver's side and close ALL the doors except the driver's. This will stop the system from locking the doors while you are trying to set up the key. After that, with the key in the ignition and the other keys you wish to program in the vicinity, push and hold the button on the fob that you want to activate until the hazard lights flash twice.
