How to program the remote keyless entry (RKE) transmitters and Key Fob on Ford Focus?

Programming of remote keyless entry (RKE) transmitters requires four simultaneous devices yet must be done when the battery is fully powered up and the anti-theft system remains disarmed. Start by using electronic door unlocking followed by door closure to prevent contradictory chimes from sounding. Execute the ignition switch four times between the off and run positions throughout six seconds before resetting it back to off. A single sound signals that you have moved into the learning mode. The new RKE transmitter code programming process completes successfully after pressing any button on the programmed device within 20 seconds and hearing a confirmation tone. The learning mode will re-initiate itself after each successful programming session for another 20 seconds to allow programming four transmitters. The programming process for supplementary transmitters requires repeated button execution inside the allotted time span. The system concludes the learning phase either when a user turns the ignition to run position or reaches 20 seconds without adding new transmitters or makes 4 successful programming attempts. When programming incorrectly the stored codes remain unaffected while new RKE transmitters will be the only accepted ones. Perform a final test of all programmed RKE transmitters through the remote locking and unlocking functions.

Ford Focus Key Fob has functionality for keyless entry and basic security for the vehicle. The compact Key Fob has a black casing which normally consists of three push buttons for locking, unlocking, and sounding the horn. Besides, shape and size depend on model configuration. A small chip, a short-range radio transmitter, and a battery work inside to send an encrypted code from the button to the onboard receiver. The coded signal is based on a rolling sequence changed at every activation. This helps deter code grabbing and significantly reduces the chance of two remotes sharing the same code. The operating range is generally 15 to 60 ft, allowing the driver to lock or unlock the vehicle from a reasonable distance. When the battery dies or the internal circuitry gets damaged, the Key Fob may stop functioning. As a result, the door may not respond, or on certain systems, the engine may not start. The Focus owner's Ford branded system lets them keep the transmitter paired normally, while a spare Key Fob is a good idea in any case. By choosing the Ford Focus option when buying a Key Fob, you can rest assured of the rolling code compatibility.
