Code Changing
BL 5000
Remove the lock from the door.
Remove the 4 red coloured retaining screws from the back of the keypad. Take extra care to keep the
keypad on a flat surface when removing the cover plate as this has several springs attached.
You will now see there are 4 red coloured coded tumblers and 6 blue coloured un-coded tumblers
plus 1 clear tumbler (C button).
To change your code push the C button and hold it. You can then easily remove one or more of your
coded and un-coded tumblers using the tweezers supplied.
Please not you should never remove the C tumbler or take your finger off of the C button when
changing your code.
Please note the different shapes of tumblers before reinserting them into the lock body. Firstly there
is a difference in shape between the coded and un-coded tumblers as illustrated below, Secondly
when refitting the tumblers into the lock body they must be fitted facing the correct way, again see
the illustration below. All square cut-outs must face outwards. Once inserted correctly the dimple on
the tumblers will sit in the cut-out on the coding chamber.
After you have refitted the tumblers and have made a note of the new code please replace the metal
plate and the 4 red screws.
Please note-with the tumblers provided you can either increase the number of digits in your code to
5-6 or reduce to 2-3.
