Using The Key - PEUGEOT 208 Handbook

Access
If one of the doors or the boot is still
open or if an electronic key has been
left inside the vehicle, the central
locking does not take place.
When the vehicle is locked, if it is
unlocked inadvertently, it will relock
automatically after about thirty seconds
unless a door is opened.
The folding and unfolding of the door
mirrors by the remote control can be
deactivated by a PEUGEOT dealer or a
qualified workshop.

Deadlocking
Deadlocking renders the exterior and
interior door controls inoperative.
It also deactivates the manual central
control button.
Therefore, never leave anyone inside
the vehicle when it is deadlocked.

Using the key

Turn the key to the rear in the driver's door
lock to lock the vehicle completely.
Turn the key to the rear again within
five seconds to deadlock the vehicle.
Using the remote control
Press the closed padlock to lock
the vehicle completely.
Press the closed padlock again within
five seconds to deadlock the vehicle.
Deadlocking is confirmed by fixed
lighting of the direction indicators for
approximately two seconds.
Depending on version, the door mirrors
fold at the same time.
