On latch locks only. The outside knob and inside handle
retract the latch when turned TOWARDS the door frame.
The spindle is positioned at the wrong angle.
The knob will not turn after entering the original code.
The code does not match the card.
The knob will not turn after entering a newly changed code.
One or more of the code tumblers are the wrong
way around.
The latchbolt does not move smoothly in and out.
The lock is installed incorrectly.
The inside and outside knobs do not return easily to the
centre position after use.
The spindle is too long for the door thickness.
The inside handle does not retract the latch.
The spindle is too short for the door thickness.
The inside lever handle does not return to the upright
position after operating.
The lever return spring is broken.
The latch does not engage and so the door remains
unlocked after use.
The latch is not entering the strike.
Refer to the installation instructions. Remove lock from door and reposition the
spindle as shown in the instructions. On hold open locks ensure that the blue
handing screw on the lever handle plate is in the correct hole.
Remove the lock from the door, turn the lock case upside down and check
that the coloured tumblers correspond with the code on the card.
NB: the ‘C’ tumbler is not coloured - but MUST start every code.
Re-read the code change instruction and check that the square notches
on the tumblers face to the outside edge of the lock with the square edge
on top.
Check that the lock is square on the door and positioned
accurately over the latch. Check that the latch is positioned
horizontally and parallel to the door surfaces.
The spindle must not project more than 30mm (1
3
/
16
”) into the inside handle.
If it does then it will be trapped between the front and back handles and
prevent them moving easily. The spindle must be shortened.
The spindle must project from the inside face of the door by at least 8mm (
5
/
16
”)
so as to engage the handle. The spindle may have been cut too short during
installation. Call the Helpline to obtain a longer spindle.
Replacement spring required.
Your door or frame may have warped since the lock was installed. Check that
the latchbolt is lined up with the strike aperture and adjust the position of the
strike as necessary. Make sure the deadlocking plunger cannot enter the strike
aperture alongside the latch bolt when the door is closed.
