There is a procedure to open the doors in a lock out. You must pull up on the driver's door handle then insert the key and turn it counterclockwise while at the same time pulling the key as if you were trying to pull it out. You will be met with a lot of resistance but the lock will open provided your actuator is not froze. This is a tricky procedure and will no doubt take several practices to be able to pull it off. Good luck!

The only real way to do it safe with minimal damage is to disconect the central locking mechanism located inside the trunk lid.but you have to get the trunk lid open than everything will be manual.

Emergency entry on the E34 chassis 5-series is to insert key in the passenger door, turn key to full unlock position and pull up on the door handle. This should get the door open, even if the battery is dead.

SOURCE: Central Locking not working

Hi Craig,
I'm running a E34 Tds Touring with a similar problem, my rear doors and tailgate have dropped of the central locking circuit.
I have been told it is the Central locking Module a large black box under the dash that is faulty, apparently a common problem.
Hope this points you in the right direction,
Please remember to rate my effort!

SOURCE: 2003 bmw 325i keys does not unlock and the door

insert the key into the drivers side or passender side front door, twist the key and pull open on the handle at the same time and the door will open. It might take a few times to get it, but this does work, source BMW AG Munich.

SOURCE: Z4 Central Locking problem - drivers door.

looks like you will need a drivers door lock actuator (contains the latch)if the door will not unlock with the remote either.the lock cylinder usually will fail since you had to use it everytime to unlock the door. the lock cylinder is vin specific so expect a delay when its ordered from the dealership.i would probably expect around $800 for the complete repair, kinda pricey but the dealership will go out of its way to retain a customer.

shorted wiring in doors or shorted door lock actuator in door. A grounding of a wire makes them lock normally. SO, any bare wire touching metal will ground it and lock the doors.

Principles of Operations
The Door Switch Lock Function When a door lock switch is moved into the lock position or a door lock cylinder is rotated to the lock position, the door lock switch grounds the lock circuit input to the central security module (CSM). The CSM then provides 12 volts to one side of the door lock actuators contained in the door latch unit and simultaneously grounds the other side of the door lock actuators. This completes the door lock actuator circuit, causing the door lock actuators to rotate a cam assembly, which then locks the doors. The 12 volts that the CSM provides to the door lock actuators are provided to both door lock actuators from a single pin on the CSM electrical connector.
The Door Switch Unlock Function When a door lock switch is moved into the unlock position, the door lock switch grounds the unlock circuit input to the CSM. The CSM then provides 12 volts to the opposite side (relative to locking the door) of the door lock actuator(s) contained in the door latch unit and simultaneously grounds the other side of the door lock actuator(s). This completes the door lock actuator circuit, causing the door lock actuator(s) to rotate a cam assembly in the opposite direction, which the unlocks the door(s). The 12 volts which the CSM provides to the door lock actuator(s) are provided to each door lock actuator from the individual pins on the CSM electrical connector.
--------------------------------------------------------
CSM Self-Test The CSM has a self-test which can be entered into by using a diagnostic tool. This self-test will monitor the following CSM door lock inputs:
  • Unlock switch (DTC B1311)
  • Lock switch (DTC B1300)
  • Exterior lock switch (DTC B1309)
  • Exterior unlock switch (DTC B1341)
Before running the self-test, the following conditions must be met:
  • The ignition switch must be in position II
  • The driver and passenger doors must be unlocked
  • The driver and passenger doors must be opened
  • The hood and liftgate must be closed
  • The set/reset switch, and liftgate release switch are not actuated
It is important to note that all of the diagnostic trouble codes (DTCs), with the exception of B1551 and B1553 can be retrieved with the self-test. DTCs B1551, and B1553 are continuous and will only be retrieved if the liftgate release is operated prior to retrieving the continuous DTCs.
Inspection and Verification
  1. NOTE: Make sure that the battery is fully charged before starting electrical diagnosis.
    NOTE: Prior to carrying out the CSM Self-Test, make sure that both the driver and passenger doors are open.
    Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

  • Binding latch mechanisms
  • Binding linkage
  • Misaligned door
  • Central junction box (CJB) fuse(s)
  • Wiring harness
  • Electrical connector(s)
  • Door lock switch(es)
  • Door lock actuator(s)


Module Controlled Functions
The central security module (CSM) covers the following functions:
  • Central door locking
  • Double door locking
  • Anti - theft alarm incorporating
    • forced entry
    • radio theft
  • Radio frequency remote control of

For additional information, refer to Section 419-01A Anti - Theft - Active, Section 501-14A Handles, Locks, Latches and Mechanisms, and Section 501-14B Keyless Entry/Computer Operated Locks.

The CSM is in the passenger side kick panel I think.

Good luck

turn key twice when opening, ie turn right. once drivers door will unlock, turn twice passengers doors will unlock, and locking is turn anti clock wise once will lock all doors, turn twice will set door dead locks.dead locks will stop openand lock internal button working and handle from opening door. the same actions can be applied to the remote one press drivers door, two press passenger doors, press and hold unlock button for 5 seconds and rear window will open.

Automatic door locks will not lock rear doors, they open fine when manually locked but will not lock with switch key fob or when put in gear.


You mean that the central locking system will not lock the rear doors but you can do so manually.

Get inside the vehicle and close all doors.

On each rear door, lock and unlock the mechanism manually a couple of times. In other words do not use the key pad.

Then leave both rear doors in the locked position (manual locking) and operate the lock button on you key pad to operate the central locking system. Wait a few seconds then hit unlock on your key pad and a few seconds later hit lock on your key pad.

If the system fails to lock your rear doors you will need to get the vehicle to an auto electrician to check out the issue and rectify it for you. There are a number of possible causes which cannot be identified without physically checking the system. So you will need to have this rectified by a professional.

Without diagnosing this problem myself, the possible causes are MANY!
Best solution is take the vehicle into a Hyundai Dealership and have it diagnosed/troubleshot by a qualified technician.
