The company that pioneered the first microprocessor-controlled vehicle security and remote start systems, the first PC-programmable systems, and the first to offer 66-bit Clone Safe Code-Hopping™ encryption has done it again.

Responder LE is destined to become the new reference standard for 2-Way hybrid vehicle security & remote start systems. It will protect your vehicle and its contents, start the engine with the push of a button from the comfort of either home or office, and confirm all commands with GhostLight™ LEDs.
