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.
Refer to the code change instructions overleaf. Remove the
lock from the 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.
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 latch bolt 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.
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.

.
The spindle must project from the inside face of the door by at
least 8mm so as to engage the handle. The spindle may have
been cut too short during installation. Call the
Helpline
to
obtain a longer spindle.
The spindle must not project more than 30mm 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.
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.
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 coloured tips on top.
Remove the lock from the door, turn the lock case upside
down and check that the red tumblers correspond with the
code on the card.
NB: the ‘C’ tumbler is not coloured - but MUST start every code.
PROBLEM AND PROBABLE CAUSE
ACTION
The
500
series mechanical lock should be specified
for doors requiring full-size lever handles, passage set
operation during normal working hours, and code lock-out
by deadbolt (525 model only). The key can be used by
security and cleaning staff to retract the latch as well as the
deadbolt without using a code. The inside lever handle will
always retract the deadbolt of the 525 model, thus avoiding
accidental lock-ins and meeting safety regulations.
