This is the iDatalink ADS-TB Bypass Interface Module. The ADS-TB handles one job and handles it well: immobilizer bypass. During a remote start it satisfies the vehicle's factory immobilizer so the engine will run without a key present, then hands control straight back when you get in and drive. Your factory security stays intact. It's a standalone module, so it works alongside any aftermarket remote starter rather than needing a BLADE dock. If you also need door lock control or CAN-bus integration, the ADS-ALCA covers all three. We flash it for you. Tell us your vehicle's year, make and model at checkout and we'll load the correct TB firmware before it ships. If you'd rather do it yourself, you'll need an ADS-USB Weblink Updater, sold separately. Not sure this is what your vehicle needs? Search your vehicle or call us on 647-439-4485.
