Hole for key blade - to loosen the cover.
To access the lock cylinder, the door handle's plastic cover must be removed - this is also done with the key blade:
Press the key blade approx. 1 cm straight up into the hole on the underside of the door handle/cover - do not prize.
The plastic cover loosens automatically by means of the torque when the blade is pushed straight up and into the opening.
Then insert the key blade in the lock cylinder and unlock the door.
Refit the plastic cover after unlocking.
When the driver's door is unlocked using the key blade and is opened, the alarm is triggered. It is switched off by inserting the PCC in the ignition switch, see Alarm - remote control key not working.
