Keyless Entry Remote Repair

A smart entry system is an electronic lock that controls access to a building or vehicle without using a mechanical key. A remote keyless system (RKS), keyless entry, or remote central locking refers to a lock that uses an electronic remote control as a key. The system is activated by a handheld key or automatically by proximity.

Remote keyless systems perform the functions of a standard car key without requiring physical contact. When the key is within a few yards of the vehicle, pressing a button on the remote can lock or unlock the doors. Sometimes, these keys can perform other functions like rolling the windows up or down. A remote keyless system can include a keyless entry system (used to unlock the doors) and a remote keyless ignition system (used to start the engine).

Some cars include a proximity system that can be triggered if a transponder car key is within a certain distance of the car. These keys are commonly called smart keys, hands-free, or advanced keys. Smart key systems are commonly found on a wide range of vehicles, though the exact method of operation can differ between brands and models. In general, a vehicle can be unlocked without the driver needing to physically push a button on the key fob to lock or unlock the car. Smart keys also allow the user to be able to start or stop the ignition without physically inserting a key and turning the ignition. Rather, the vehicle is able to sense that the key is approaching the vehicle.
