The passenger compartment doors have conventional locks with locking plates located on the B and C pillars and built-in switches to prevent the door from closing too tightly.

The locking strips of the bonnet and the rear luggage compartment door are built into the latches located on the vehicle body.

The hood can only be opened with the ignition key inserted into the hood lock cylinder. To open the hood:

• 1. Turn the key all the way to the left; this releases the hood lid safety catch.
• 2. Turn the key all the way to the right, this allows you to open the hood.
• 3. Turn the key to its original center position and remove the key.

NOTE: After opening the hood, to avoid accidental damage/breakage of the ignition key if it is accidentally hit while working in the engine compartment, the key must be removed.

The tailgate can be unlocked using the tailgate switch located on the instrument panel. It can also be opened using the ignition key by unlocking the lock located in the tailgate or by pressing the tailgate release button on the remote control transmitter twice.

The door latch mechanisms are operated by means of a conventional lever-and-cable drive connected to the outer and inner handles.

The electric door lock system consists of the components used in the mechanical door lock system, as well as an additional electric door lock switch, electric drive, electrical wiring and electrical circuit protection components.

The door handle and latch are removed from the inside of the door panel. The handle and latch cannot be removed separately. The drive rods and latches are covered with a special shield on the inside of the door.

The remote control transmitter performs the following functions:

• Unlocking and locking the driver's door.
• Unlocking and locking all doors.
• Unlocking and locking the tailgate.
• Activation and deactivation of the double locking system and interior scanning (if available).
• Enabling and disabling the anti-theft alarm system.
• Disabling a triggered alarm.

Input and output signals

The keyless entry locking system receives input signals from the following elements:

• Ignition switch (positions I and II).
• Door soft close switches.
• Hood opening switch.
• Tailgate opening switch.
• Remote transmitter
• Switch for locking the anti-theft alarm system of the folding luggage compartment door.

The keyless entry locking system distributes input signals to the following elements:

• Central Timer Module (CTM) (vehicles manufactured up to 08/2001).
• GEM (vehicles manufactured from 08.2001 onwards).
• Electric door lock drives.
• Electric motors for double door locking.
• LED indicator (light emitting diode).
• Direction indicators.
• Audible emergency alarm.

Remote transmitter

The keyless entry locking system is completely independent in terms of function, but is fully integrated into the anti-theft alarm system module and double door locking (vehicles manufactured up to 01.2001) or into the GEM (vehicles manufactured from 01.2001 onwards). The remote control system consists of a transmitter and an antenna (radio frequency system).

In the RF system, the remote control transmitter will work without pointing the transmitter at the car. The normal distance between the remote control transmitter and the antenna is 10 meters.

Before the remote control system can be used, each transmitter must be initialized to the vehicle. A maximum of four remote control transmitters can be initialized to each vehicle. All remote control transmitters must be initialized at the same time.

The keyless entry locks will not operate when the ignition switch is in the RUN position.

Locking and unlocking

The remote control transmitter is located in the ignition key and contains three system control buttons.

Press the LOCK button once to activate the central locking system and the alarm system.

Press the LOCK button twice within two seconds to activate the central locking system, double door locking system, alarm system and interior scanning system (if equipped).


Pressing the UNLOCK button once will release the double door locks, disable the alarm system and unlock only the driver's door.

Pressing the UNLOCK button twice within three seconds unlocks the remaining doors.

For vehicles manufactured from 01.2001 onwards, the unlocking mode can be changed from a single press to unlock the driver's door only to unlocking all doors (flaps). PRESS the LOCK and UNLOCK buttons simultaneously and hold for 4 seconds. PRESSING and holding the buttons again for 4 seconds will return to the original mode. When each mode change is recognized by the module, the direction indicators will flash twice.

Pressing the LIFTGATE RELEASE button twice within three seconds unlocks the luggage compartment door.

Double door locking

Double door locking prevents the doors from being opened using the interior door handles.

Double door locking is activated by turning the key in the driver's or passenger's door lock to the unlock position and then to the lock position within three seconds, or by using the remote control transmitter.

Successful operation of the double door locking is confirmed by the double illumination of the direction indicators and the LED indicator.

Activation of double locking will be delayed if the control module detects an open door condition. The anti-theft alarm and double locking module receives this input from the CTM (vehicles manufactured up to 08/2001) or GEM (vehicles manufactured from 08/2001 onwards), which receives its input from the door ajar switch.


If the vehicle battery is discharged after the double door locking has been activated, then when the door is opened using the key, the double door locking is mechanically deactivated (only in the door being opened).

Anti-theft alarm system and double door lock module (vehicles manufactured up to 08.2001)

For additional information, see Section 419-10. The anti-theft alarm and double door locking system module is equipped with a backup battery that provides power to the memory of the programmable transmitter(s) in the event of a vehicle battery disconnection.

Operating principle

Door switch operation when locked

When the door lock switch(es) is moved to the lock position or when the door lock cylinder is rotated to the lock position, the door lock switch(es) grounds the locking electrical circuit input to the central security module (CSM). The CSM then supplies 12 volts to one side of the door lock actuators contained in the door latch assemblies and simultaneously provides ground to the other side of the door lock actuators. This completes the electrical circuit to the door lock actuators, causing the door lock actuators to rotate the cam assembly, which then locks the doors.

Door switch operation when unlocking

When the door lock switch(es) is moved to the unlock position, the switch grounds the unlock electrical input to the CSM. The CSM then supplies 12 V to the opposite side (relative to the door(s) locking) of the door lock actuator(s) located in the door(s) latch(es) assembly(ies) and simultaneously grounds the other side of the door lock actuator(s). This completes the electrical circuit of the door lock actuator(s), causing the door lock actuator(s) to rotate the cam(s) in the opposite direction, which causes the door(s) to unlock. The 12 V that the CSM supplies to the door lock actuator(s) is supplied to each door lock actuator from individual pins of the CSM connector.

Unlocking the rear tailgate

When the liftgate release switch is pressed, the switch grounds the input circuit to the CSM. When the CSM receives a ground signal, the module supplies 12 V to the liftgate release actuator.

Operation of door lock cylinders

Both the driver and passenger front doors can be unlocked by inserting the key into the lock cylinder of either door. When the ignition key is inserted into the lock of either door and turned to the lock position, a linkage causes a cam in the door latch assembly to rotate. When the cam in the door latch rotates, it mechanically moves the door latch (in the door in which the key is used) to the lock position. The other doors are locked electronically.

Keyless entry

When the remote transmitter button is pressed, it transmits the corresponding command to the CSM as a radio frequency. The CSM receives the command from the remote transmitter via the antenna built into the CSM.

When the CSM receives a command from the remote transmitter, it then sends the appropriate output signal to control the required devices. These devices that receive the output signal include:

• Front and rear door locks.
• CTM
• Electric motor for opening the luggage compartment door.
• Right and left turn signals.

The CSM sends a signal to the CTM when the door step lights need to be turned on.
