How are Remotes Programmed?

Remote keyless entry fobs emit a radio frequency with a designated, distinct digital identity code. In as much as "programming" fobs is a proprietary technical process, it is typically performed by the automobile manufacturer. (In point of fact it is a computer in the car which is programmed in the process, not the fob itself.) In general, the procedure is to put the car computer in 'programming mode'. This usually entails engaging the power in the car several times while holding a button or lever. It may also include opening doors, or removing fuses. The procedure varies amongst various makes, models, and years. Once in 'programming mode' one or more of the fob buttons is depressed to send the digital identity code to the car's onboard computer. The computer saves the code and the car is then taken out of 'programming mode'.

As RKS fobs have become more prevalent in the automobile industry a secondary market of unprogrammed devices have sprung up. Some web sites sell steps to program fobs for individual models of cars as well as accessory kits to remotely activate other car devices.
