Mechanical Digital Locks

The latch has broke on the digital lock, can I get a replacement.
Yes a replacement latch can be ordered, code SBL999.
The springs have collapsed on the inside handle do you do a replacement for the springs.
We do not sell the springs as a separate item but we do offer a new handle set which can be
used to replace the inside handle. This can be ordered by code ZKI-handle followed by the
product code such as SBL310.S or SBL320.S
I have some fixings missing in the parts pack, can I order spare parts .
Yes parts can be ordered on request.
When I put the spindle through the door it does not locate in the inside unit.
Check that the spindle has been cut to the correct length.
If the spindle has been cut too short replacements are aviailable on request.
The latch will not return to its fully extended position once having operated it through either the
external or internal part of the digital lock.
There may be something restricting the motion. Remove the unit from the door and check there
are no loose shavings or timber obstructing the spindle or mechanism.
When re-securing the unit to the door check that the spindle is not too long and therefore
bottoming in both the internal and external sides of the digital lock. Bottoming is caused when
the length of the spindle is greater than the door width and the amount of engagement in the
internal and external units added together. If the spindle is too long, it can begin to twist or
bend, when the fixings are tightened, preventing the unit from operating correctly.
Do not over tighten the unit as this can cause the mechanism to become compressed and
prevent correct operation, particularly on timber doors if the surface is not flat
The latch does not enter the striker supplied.
The entire latch is not intended to enter the aperture of the striker. You will notice two parts
when looking at the head of the latch; there will be the main body and a separate radius part
that can be pushed in independent to the main latch body. This is the anti-thrust feature of the
latch and is intended to sit on the striker plate itself allowing the main part to enter the aperture
when the door is in the closed position maintaining the anti-burglar function.
