Central locking in BMW E60 models controls door locks, trunk lid or luggage compartment lock and fuel filler flap lock. The electronic functions of central locking are spread out over several control modules, with sensors and actuators connected directly to a control module in the vicinity of their installed location. The car access system (CAS) module is the master control module for central locking.

The lock mechanism in each door consists of a latch, an exterior door handle and an inside door lock release handle. Only the driver door (left front in North America) is equipped with a lock cylinder. The exterior door latch is responsible for locking, unlocking and latching the door shut. The latch itself is pretty reliable, however having the electronic lock solenoid integrated in the latch creates some problems. The lock solenoids fail over time, leaving you with a malfunctioning lock. If it is the driver lock, you can still lock and unlock with the key. With other kinds of doors, you may not be so lucky. If you are having a problem with the lock, try cleaning and lubricating the latch. I find this will restore function of the lock from time to time. If I can successfully restore function this way, I still replace the latch to avoid future problems. It is a good test to see if the problem is electrical or mechanical.

Each inner door trim panel is equipped with an SRS airbag. For safety reasons, be sure to disconnect the vehicle battery before beginning work on the door panel. See our tech article on the battery.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Remove the interior door panel and window regulator. See our tech article on window regulator replacing.

The door latch and door power lock solenoid is replaced as one unit.

To install the new latch reverse the order of the steps.
Figure 7

To install the new latch, reverse the order of the steps. When installing the latch, align the lock cylinder rod (red arrow) with the door latch. If you are having trouble aligning the two, use the key in the lock cylinder to rotate the rod while installing the latch. I find this helps to get them to mate. Remember to check the function of the latch before installing the door panel. I suggest closing the latch with a flathead screwdriver while the door is open. Then open it using the cables once you attached them. This will ensure it is working.
