Description and Operation
Door Lock Mechanism

For most markets, the remote central locking system also, in corporates 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 Sy stem and operate the engine immobilisation system.
The central locking system employs single key access to the driv er's door, trunk lid and ignition switch/steering column lock.
An additional green headed valet or park ing 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 si ngle 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 lock ed simultaneously from inside by pressing the driver or front passenger door sill
button down. Each rear door can be independently locked by si milarly 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 automati cally 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 th e interior. To deadlock the vehicle, the
key is inserted in the door lock and turned to the unlock (rearw ard) position, then within three seconds, turned to the lock
(forward) position and released.
Remote Operation

Remote Central Locking Transmitter Unit

A four-button transmitter unit provides for remote controlled central locking of the vehicle.
The button bearing a red closed padlock sy mbol locks the vehicle and arms the security system. To remote 'single action'
lock, the transmitter is pointed towards the vehicle and this bu tton is pressed and released. To deadlock the vehicle, the
above operation is repeated with in three seconds. This function can also be used to remote close any windows. Completion
of deadlocking is indicated by an audible 'chirp' from the security system and a single flash from the direction indicators.
The vehicle is unlocked and the security system disarmed by pressing the button with the open padlock symbol.
The trunk lock can also be remotely released by op erating the button bearing the trunk lid open symbol.
The button with dipped headlamp symbol is for emergency us e. When depressed three times within three seconds, it
switches the headlamps on for 25 seconds and operates the vehicle alarm 5 times.
