This two-point closure is fitted as standard with a half europrofile cylinder, including three keys. Alternatively, the closing mechanism can now also be fitted with a knob cylinder instead of a cylinder lock. A knob cylinder is like a normal cylinder but featuring a rotary knob. This rotary knob is used to release the lock. No keys are therefore required to open the roof access hatch, so the roof access hatch can also serve as an emergency exit/emergency hatch.
This new option has already been incorporated into the online roof hatch configurator.
