Remove the batteries and the eight small screws holding the case together. With the
keypad facing down remove the back cover, this may need a little encouragement at
the battery compartment end.

Ther are more tracks on the pcb than the ones shown, i have only shown the
important ones.
Break tracks at points A and B
Solder a wire from 1 to 2
Solder a wire from 3 to 4
The track you break at point A is connected to point 2, check this with a continuity
meter before breaking the track to check you are on the right track!

then switch the key lock switch on.
