Description


Keyless Entry

Keyless Entry

Performs lock and unlock tasks without physical contact with the vehicle. Power door locks can be controlled from several feet away or even within a building using a remote fob. The fob emits a radio frequency that is digitally encoded to prevent frequency stealing so no one can enter into your vehicle without your wireless transmitter.

Dual Zone Shock Sensor

Dual Zone Shock Sensor

This shock sensor utilizes warning chirps for minor disturbances and will trip the alarm if it detects more serious impacts or disruptions. Most dual zone shock sensors have adjustable sensitivity to reduce false alarms or warnings. These sensors let would-be thieves know that your vehicle is equipped with an advanced alarm system and to keep away.
