2012 BMW X3 — what this service covers

We program BMW keys via bench work on the CAS module (Car Access System) for 2006-2012 BMW models. Pull your CAS, ship it to us, and we will cut a new key blade and program a fresh transponder. On CAS3+ and CAS4+ the DME (engine computer) ships with the CAS: those versions encrypt the ISN, and the new key's ISN can only be read from the DME. CAS2, CAS3 and CAS4 need the CAS alone. Ships back the next business day.
