Remote Car Start

A remote keyless system is a system designed to remotely lock, or unlock, access to premises or automobiles. more...

In the case of automobiles it duplicates all of the features of a standard car key with the added convenience of operating the power door locks, eliminating the need to physically manipulate a key into a lock as well as being able to do so at a distance. A remote keyless system can include both a remote keyless entry system (RKE) and a remote keyless ignition system (RKI). It works on the same principle as some television remote controls -- sending pulses of radio frequency energy on a particular frequency. These pulses are interpreted by the receiver in the automobile, which, in turn, performs the appropriate function. Newer systems implement encryption to prevent car thieves from intercepting and spoofing the signal.

The functions of a remote keyless entry system are contained on a small, hand-held fob attached to the keychain or built into the ignition key handle itself. Buttons are set aside to either lock or unlock the doors, plus open the trunk (or, on sport utility vehicles and station wagons, unlock/open the rear tailgate). Some cars will also close any open windows and roof when remotely locking the car. On many newer cars, the remote keyless fob also contains a button to activate the car alarm. Cars with remote keyless ignition systems can be started by the push of a button on the handheld fob.

Other cars have a proximity system that is triggered if a keylike transducer is within a certain distance of the car.

For offices, or residences, the system can also be coupled with the security system, garage door opener or remotely activated lighting devices.
