E-Z Key Passive Entry System

The ultimate in vehicle entry and start convenience, the E-Z Key Passive Entry System uses an integrated key fob sensor instead of a traditional key. This extended-range system is smart enough to sense your approach, electronically "read" and validate the unique code embedded in your fob – which can remain in your pocket or purse at all times – then automatically turn on the interior lights and unlock the doors. Once you're inside, your LaCrosse starts with the push of a button.  This feature includes automatic door lock/unlock and theft deterrent with engine immobilizer. Included with the Premium II, Premium III, and Touring equipment groups.
