Here’s a SLS Cashguard fitted with a lagard 66e electronic lock. Staff could not open the safe although the code was working fine and the keypad was rotating.
Now these are tough safes, according to my files it is a Euro grade 3 safe which has a cash limit of £35,000 pounds. SLS were renown in the industry for making fantastically strong safes.
This took a few drill bits to open and a fair amount of time. My first plan didn’t work so I had to try another method. Fortunately this worked, it took ages to get the handle to fully turn.
A component inside the safe had become loose effectively locking the safe shut from the inside.
Once open I made sure everything was connected properly and repaired the door.
Its a very simple mechanism that activates when the safe is subjected to an attack, effectively each re locking device shuts the safe down another level.
