Vehicles built 02/2004 onwards
For most markets excluding North America and Japan, the remote central locking system incorporates a double locking facility for optimum security. All locks use the Tibbe key system, using six elements and four cuts. The keys include 'in-key' transponders which are programmed to the vehicle engine immobilization system by using the Jaguar approved diagnostic system.
The central locking system employs single key access to the driver door, luggage compartment and ignition switch/steering column lock.
When the vehicle is not locked, each door catch can be externally released by the corresponding exterior door handle which is operated by a single rod. When unlocked, or central locked, the door latches can also be released by the interior handles, each of which are operated by a single cable. Operation of the front door interior handles will also unlock the rear doors. Use of the key in the driver door lock cylinder operates the lock by a short rod to provide locking of the door latch. This in turn locks all other doors and the luggage compartment through the central locking system. These locking functions can also be achieved by use of the remote transmitter.
For most markets, a 'drive-away door locking' feature automatically locks all doors and the luggage compartment when the vehicle exceeds 7 km/h (4 mile/h).
Key operation
To central lock or unlock the vehicle, the key is inserted in the driver door lock cylinder, turned clockwise or counter clockwise respectively, and released. Holding the key in the lock position for one and half seconds will close all windows. Releasing the key stops all operations. Central locking of the vehicle locks all the doors, the luggage compartment, and sets the alarm system. In addition to all of the above functions, double locking prevents the doors opening from the interior. To 'double lock' the vehicle, the key is inserted in the driver door lock cylinder and turned to the unlock position, then within three seconds, turned to the lock position and released. The same procedure is required to unlock a 'double locked' vehicle as with a central locked vehicle. The key is inserted in the driver door lock cylinder and turned to the unlock position. This function can also be activated using the remote transmitter.
If an attempt is made to lock the doors through either the driver or passenger door interior handle, when that door is ajar, all doors will lock temporarily. If the lock signal was received at the driver door it will unlock, if the lock signal was received at the passenger door all three passenger doors will unlock.
The fuel filler flap switch is used to allow the driver to release the fuel filler flap from inside the vehicle. This function can be used at all times providing the vehicle is not locked.
Keyless Entry
The Integrated key remote transmitter operates the following functions:
- unlocking the driver door
- unlocking/locking all doors
- releasing the luggage compartment lid
- activate/deactivate the double locking
- arms/disarms the anti-theft alarm system, interior scanning system and the inclination sensor (if equipped)
- activates global closing
- deactivates a triggered alarm
Inputs and Outputs
The keyless entry/computer operated lock system receives inputs from the following:
- ignition switch (positions I and II)
- door ajar switches
- hood switch
- luggage compartment switch
- remote transmitter
The Front electronic module (FEM) distributes outputs to the following:
- door lock actuators
- double locking motors
- turn signals
- alarm horn
- luggage compartment latch
- power window motors for global closing
Transmitter, Keyless Entry Remote
The keyless entry/remote operated lock system is completely independent in function but fully integrated within the FEM. The remote control system consists of a transmitter and an antenna (radio frequency system).
The remote control transmitter for the radio frequency system will operate without the transmitter being directed at the vehicle. The normal range between the transmitter and the antenna will be up to 10 meters for the USA, Canada and the rest of the world. The normal range between transmitter and antenna will be up to five meters for the UK and Europe and three meters for Japan.
Before the remote control system can be used, each transmitter must be initialized to the vehicle. A maximum number of four transmitters can be initialized to any vehicle. All remote transmitters must be initialized at the same time.
The keyless entry/remote operated locks will not operate when the ignition key is in the ignition switch.
Locking and Unlocking
The remote transmitter is integrated into the key and contains four buttons (lock, unlock, trunk release, headlamp convenience). To operate the system:
Press the lock button once to activate the central locking system and the alarm system.
Press the lock button twice within three seconds to activate the central locking system, double locking system, alarm system and the interior scanning system (if equipped).
Press the unlock button once to deactivate the double locking, the alarm system is deactivated and only the driver door is fully unlocked (this is programmable using the approved Jaguar diagnostic system).
Press the unlock button twice within three seconds, will unlock the remaining doors (this is programmable using the Jaguar approved diagnostic system).
Press the luggage compartment release button once releases the luggage compartment lid. The vehicle must be unlocked and at vehicle speeds below 7 km/h (4 mile/h).
Press the headlamp convenience button once to activate the headlamp main beam function, press the headlamp convenience button again to deactivate the headlamp main beam function. This function will automatically deactivate after 30 seconds.
Press the headlamp convenience button three times within three seconds to activate the alarm, press the headlamp convenience button again three times within three seconds to deactivate the alarm.
Double Locking
Double locking prevents the interior door handles from unlocking the doors.
Double locking is activated by turning the key, using the driver door lock cylinder to the unlock position and then to the lock position within three seconds or by pressing the lock button twice within three seconds on the remote transmitter.
Successful double locking is indicated by the turn signals flashing twice, one short flash followed by a long flash.
Double locking will be inhibited if the FEM senses the hood, a door or the luggage compartment is ajar or open. The FEM receives its input from the door ajar switches.
If the vehicle battery becomes discharged after the double locking has been activated, opening the drivers door with the key will mechanically deactivate the double locking on the drivers door only.
