The Honda/Acura Immobilizer anti theft system uses a low power transponder mounted in the head of the ignition key. When the vehicle is started, the key cylinder module converts the transponder signal and sends a secure coded signal to the engine control module. If the signal is correct, the car will start.
This special module uses a unique computerized sequence to learn the secure code from the key cylinder module and repeats it when remote start is activate, eliminating the need to leave a key in the car. This unit integrates into the wiring for Honda/Acura anti theft immobilize system allowing remote start while retaining the normal function of the factory immobilize anti theft system. On board LED confirms proper programming. Instructions included. Required for Honda/Acuras with immobilizer keys to incorporate and allow aftermarket remote starts.
Improved product. Will plug into some remote starts. Universal, will work with ALL remote starts.
