Clifford 320.3X


Clifford's elegant new Responder LE transceivers mark a giant leap forward in 21st century vehicle security and remote start, and an evolutionary milestone for the keychain remote. These slender & sophisticated 2-Way remote controls feature a clean sleek ergonomic industrial design, made to fit the user's hand comfortably, enabling effortless and intuitive single-handed operation as hidden GhostLight™ LEDs confirm your commands. You will love the way the Responder LE remote feels in your hand, and the many state-of-the-art system features you can access with ease, starting with the new paging-only Silent Mode2™ feature, which allows users to turn off the siren and receive notification on the remote only. With Silent Mode2, the vehicle silently alerts the user that the alarm has triggered. Contact your local dealer for more information.

SuperCode is the technology that defines the functionality of responder and the intelligence that drives its advanced features. Its protocol encompasses software-based system signal encryption (replacing hardware-based Clone Safe Code-Hopping). Multi-car operation is designed into the SuperCode protocol, so users will have all of the possible operations for two cars controllable by one remote.

2-way confirmations and notifications of many different events and commands have been designed into SuperCode, so all SuperCode-enabled 2-way systems can tell the user more about their vehicle than any other system on the market.
