• The luggage compartment can be manually   
locked with a “Master Key” and leaving the  
lock cylinder in the horizontal position which 
prevents opening by any other method (sec- 
ured for valet).
The luggage compartment release button in-  
side the vehicle will also be ignored by the GM.
Prior to 2000 MY the vehicle could be locked/ 
unlocked using the luggage compartment lock 
cylinder. 
• The glove box has a lock cylinder to secure the  
contents by manual locking with a “Master 
Key”  and leaving the lock cylinder in the hori-
zontal position which prevents opening by any 
other method (secured for valet). 
• The E38 has a lever behind the glove box han
dle which permits locking the glove box with-  
out a key. Opening still requires a key.
The valet key is not mechanically capable of
entering either of these lock cylinders.  
• The Fuel Filler Flap mechanical release is found 
in the right side of the luggage compartment.  
The “pull tether” is behind the button as shown  
on the right. 
Note:  Continuous  operation  of  locking/unlocking  will  cause  a  timed  arrest  of  the
locking  system.  When  activated,  the  timed  arrest  lasts  for  2  minutes  (or  recycle
the ignition KL15). The “crash” signal will override the timed arrest and unlock the
vehicle.
