what should be done if fail to find the combination of safe by Auto Dialer? More often drilling is required. There are different ways to drill safes, so it is important to hire the right safe technician for this work.
In the case of lock failure or lost combo, safe can be drilled in a way that leaves no visible hole. it shows a great way to do this on what happens to be a locked safe. The safe technician removes the dial or keypad, along with the dial ring and mounting plate. The professional technician will have a drill rig. It mounts to the front of the safe, screwing into the same holes used for mounting the lock. The drill rig holds the drill solidly in place and helps control it so that drilling can be done with extreme precision.
The technician’s experience and knowledge tell him what is wrong with the lock and how the lock is situated inside the safe. Accurate measuring, or use of special drilling templates, allows him to drill a hole to hit one of a number of specific parts of the lock. Often that means drilling right into the lock body which is tightly packed with lots of parts. This also needs to be done without damaging anything inside the lock.
Before getting to the lock body it is necessary to drill though the safe’s outside steel; it might be thin or it might be up to 1 ¾” thick. If it is a composite type safe there is insulation to go through. There is also normally some kind of hard-plate steel to go through. Special drill bits are required to penetrate most hard-plate. If done right, one small hole is usually required to unlock the safe. Repairs then need to be made, which involve filling the hole with a hardened tapered pin. That may restore the safe to its original security level. The lock needs to be replaced probably. When the repairs are finished and the dial is re-installed the safe could be used as before if the technician is good enough.
