This is the iDatalink ADS-ALCA Interface Module. The ADS-ALCA is a three-in-one interface: immobilizer bypass, door lock control and CAN-bus integration in a single module. During a remote start it satisfies the vehicle's factory immobilizer so the engine will run without a key present, and it gives your remote starter access to the lock, unlock and status signals it needs from the vehicle's data network. It's a standalone module, so it works with any aftermarket remote starter rather than needing a BLADE dock. This is the current 64K version. We flash it for you. Tell us your vehicle's year, make and model at checkout and we'll load the correct TB, DL+ or CA firmware before it ships. If you'd rather do it yourself, you'll need an ADS-USB Weblink Updater, sold separately. Some vehicles need additional accessories, also sold separately. Not sure this is what your vehicle needs? Search your vehicle or call us on 647-439-4485.
