Door Lock Mechanism







For most markets, the remote central locking system also, incorporates deadlocking facilities for optimum security. Door locks are eight disc, bayonet fixing barrels with integral lock/unlock switches. Keys include 'in-key' transponders which are programmed to the vehicle via the Jaguar Diagnostic System and operate the engine immobilisation system.

The central locking system employs single key access to the driver's door, trunk lid and ignition switch/steering column lock. An additional green headed valet or parking services key permits access via the driver's door, and ignition/start-up, but denies access to the trunk and glovebox. A valet switch located on the centre console switch panel above the radio, precludes normal internal access to the trunk. When the vehicle is not locked, each door catch can be externally released by the corresponding external door handle which operates via a single rod. When unlocked, or 'single action' locked, the door catches can also be released via the interior handles, each of which operates via a single cable. Operation of the front door interior handles will also unlock the rear doors. Use of either key in the external door barrel, operates the lock via a short rod to provide locking of the door latch. These locking functions can also be achieved by use of the remote transmitter. The trunk lid can be independently unlatched via a switch located on the driver's side underscuttle. This will only operate at vehicle speeds up to 8 km/h (5 mph).

All doors and the trunk can be manually locked simultaneously from inside by pressing the driver or front passenger door sill button down. Each rear door can be independently locked by similarly depressing the sill button and in some markets can be released by operating the internal door handle.

For most markets, a 'drive-away door locking' feature automatically locks all doors and the trunk when the gear selector is moved from the Park position.

Key Operation
To 'single action' lock or unlock the vehicle, the key is inserted in the door lock, turned towards the front or rear of the vehicle respectively, and released. Holding the key in the lock position will close all windows. Releasing the key stops all operations. 'single action' locking of the vehicle locks all doors, the trunk lid and the fuel filler flap, and sets the alarm system.

In addition to all of the above functions, deadlocking prevents door opening from the interior. To deadlock the vehicle, the key is inserted in the door lock and turned to the unlock (rearward) position, then within three seconds, turned to the lock (forward) position and released.

Remote Operation Refer to Keyless Entry.
