Here is a brand new Dudley grade 1 safe with an electronic Lagard 39e deadlock. The code had been lost and the safe needed opening urgently.
I have studied all versions of the Lagard electronic lock family and am pretty good at diagnosing faults when they occur. This was a simple case of lost code. After checking some obvious codes I had to resort to more invasive techniques. The safe was opened and lock replaced without damage to the safe.
If you have a safe with an electronic lock that is temperamental don’t wait until if fails, cables, keypads and locks can be replaced saving money in the long run.
