SKM21 Smart Key Motorcycle Engine Lock from Steelmate


The Steelmate SKM21 smart key motorcycle engine lock is a sophisticated transponder immobiliser. The transponder tag is a keyring style transmitting device which when in proximity of the motorcycle sends a unique code which the immobiliser responds to and allows the bike to start, without the correct transponder tag the bike will not start and an audible alarm will sound. The system arms automatically when the engine is turned off.
