Car Access System E60, E61, E63, E64, E87, E90, E91: Introduction
The Car Access System (CAS) controls access to the vehicle. The CAS control unit is, amongst other things, the master for the central locking system, the electronic immobilizer and the electrical steering lock.
The CAS is constructed differently in the various model series.
Unlike on the E65, the CAS and the ignition switch are 2 separate components on the E60.
The E87, E90 and E91 do not feature the ignition switch and conventional ignition keys. The slot and START/STOP button, similar to those on the E65, are new features.
New: From 09/2005, the BMW 5-Series a 6-Series also have this technology.
