64 12... Initialize the auxiliary heater remote key

WARNING: This page is about a different car, the 2010 BMW 550i, 2009 BMW 550i, and 2008 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

The following steps are required for initializing a new independent heating remote control or after replacing the Car Access System control unit:

  1. Close and then reopen central locking with vehicle remote control.
  2. Within 5 seconds: Switch ignition lock from terminal "0" to terminal "R" and then back to terminal "0".
  3. Press and hold down "OFF" button on independent heating remote control.
  4. Press "ON" button on independent heating remote control 3 times in succession

The vehicle's central locking closes and opens automatically on successful initialization.

NOTE: Both independent heating remote controls must be reinitialized after the Car Access System control unit has been replaced.
