Remote Start Car Alarm

Remote Start

Allows a vehicles engine to active without physical contact from the user. This feature is useful for warming up your vehicles engine and transmission to operational temperatures. In cold climates you can have your interior hot or in warm climates you can cool it down before use. All of this can be done while in the comfort of your home or office.

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.

2-Way Paging

2-Way Paging

Send commands to your remote start or alarm system and receive confirmation that those commands were carried out. Obtain updates on your vehicles security status and get driver pages on the remote. If your vehicle is being tampered with, your remote transmitter will warn you and set off the vehicles alarm.

Dedicated Trunk Release

Dedicated Trunk Release

This unit comes with trunk release capability and remote control integration for OEM alarm or add-on trunk release systems. Pop your trunk using your remote transmitter for convenience and ease of use. Carrying a handful of groceries? Arms tied up with luggage? Pop the trunk without using your key so it’s open and waiting for you when you arrive.
