Door Locks
The door locks and fuel filler flap are centrally controlled and are normally
unlocked when the left button is pressed on the alarm key fob. The boot lock
is also enabled at this time but does not release until opened using the boot
release switch, ignition key or by pressing the right button on the key fob.
NOTE: If a door is unlocked and opened with the key whilst the alarm is switched
on, the alarm will sound.
If the alarm system is off, then locking or unlocking of either door with the
ignition key causes simultaneous locking or unlocking of the other door and
the fuel filler flap by means of the central locking system.
Door Sealing
Your DB AR1 is fitted with frameless door windows. A special door sealing
system is fitted to ensure a tight fit of the door glass to the seal along the 'A'
post.
When you open a door, the window glass is automatically lowered a few
millimetres to clear the door seal.
As you close a door, the window glass is automatically raised against the
body frame rubber seals.
WARNING: Ensure that all occupants are clear when the window mechanism is
operating.
Caution: Door Seal Damage - Reconnect the battery (see Battery Reconnect Switch
1-F-35) before opening the doors to avoid damage to the door seals.

Security Systems
The primary protection for your DB AR1 is provided by an electronic
security system. Protection is further enhanced by a passive anti-theft system
(PATS) which provides engine immobilisation measures if the wrong ignition
key is used. The total system has the following functions:
• Remote Arming/Disarming via a Key Fob.
• Perimeter Sensing via switches on the doors, boot lid and bonnet.
• Boot Release on the Key Fob.
• Panic Alarm triggered using the Alarm Key Fob.
• 120dB Siren with battery back-up (in markets where audible sirens are
permitted).
• Random Code Encryption to prevent electronic scanning or grabbing of
the key fob identity code.
• Passive Anti-Theft system.
Tracker System (Optional - UK only excluding Channel Isles)
• The Tracker hardware is fitted to UK cars only and may be activated for
any owners who wish to subscribe to this additional vehicle security
system. Please consult your dealer for system details and subscription
rates.

Boot (Trunk) Lock Control
To open the boot (trunk), press the right
key fob button. The key fob red lamp will
stay on so long as the right hand button is
pressed. The direction indicators will flash
once (in markets where visible alarm signals
are permitted), the siren will chirp once (in
markets where audible sirens are permitted
and programmed) and the boot will unlock.
It is not necessary to disarm the alarm in
order to use the boot unlock feature.
Caution: Always ensure that the boot (trunk) lid is securely closed after use. The boot
(trunk) interior lights will be on when the lid is left partially open and will cause the
vehicle battery to discharge.

Alarm Key Fob - Range and Battery Replacement
The normal range of the alarm key fob is approximately 10 metres (30 feet).
If you need to come closer to the car before the key fob signal is effective,
the key fob battery probably needs replacing.
To replace the key fob battery, open the battery compartment using a small
flat bladed tool and remove the cover.
Lift out the two batteries noting the correct orientation (positive terminals
uppermost). Take care not to damage the upper electrical contact in the
battery compartment.
Fit replacement batteries (Two x Varta CR2016 3 volt batteries or similar),
observing the correct polarity. Refit the battery compartment cover and
press the outer end to engage the cover lock tab.
Test that the alarm system will arm/disarm when actuated using the key fob
from a range of approximately 10 metres (30 feet).
