The door will not open when the code is entered into the lock.
The code that has been entered previously has not been cleared,
before entering the next code, the ‘C’ must always be entered before
the code.
Check that the code that is being entered is the same code that is
either on the code card which is supplied with the instructions, or the
code that has been entered which can be found by taking the back off
and looking at the red detainers which identifies the code.
Is your spindle in the correct orientation in the
tubular latch? When positioned in the cam of the top
edge of the spindle should be leaning towards the
locking edge of the door.
I have changed the code from the original code and it will not work when I entered the new code
into the digital lock.
When changing the code, the detainers have not been put in
correctly as all detainers must have the cut out on the oustide
facing the numbers. Make sure the red detainers for the code
entered are facing upwards. The blue detainers need to be
placed into the other numbers that are not being used.
When the detainers have been removed or placed back into
the digital lock the ledger has snapped. This means when
taking out the detainers make sure that the lock is being held
upright and push down the letter ‘C’. Then shake the detainers
out of the digital lock . Also when putting the detainers back
into the unit, do not press on them but click the ‘C’ button
which will then drop the detainers down into the locations of
the digital lock.
How many digits can I enter in the code
This will depend on the number of detainers supplied with the unit. Spare detainers are supplied
with each unit and can vary allowing between 4 and 7 depending on the unit purchased.
