Topic: Bypassing
No locksmith likes a destructive entry, however sometimes there is just no other options available.
Today I encountered a lockout at an apartment.
It was a decent setup of Arrone+ Cylinder and nightlatch that had phantomly popped into the deadlock position when slammed shut.
With no letterbox available I would normally 'mickey mouse' the cylinder from the door and use the snib removal method i discussed a few years ago.
However as you will probably know the Arrone+ is a solid bodied lock cylinder and attempting to take out the retaining screws in the usual fashion would'nt be a smart move and could get messy.
I decided that the best way to attack this lock would be to use a rod style snapping attack, taking a bit of a gamble that the retaining screws were the clippable type and not the solid thread version.
So i drilled a decent hole into the meat of the lock body making sure to miss all pins and any anti-drill protection the lock might have had .
Using a tight fitting hardened rod; ala screwdriver i rolled around the edges of the hole applying force in both clockwise and anticlockwise motion and eventually fractured the retaining screws which as i gambled on, had snip off points making them considerably weaker than a solid thread screw.
Cylinder out the way, i drilled for the snib button and released the deadlock in the usual manner.
If you do suspect that the lock cylinder is fitted with a solid type screw then i would advise drilling diagonally through the lock body as to hit the retaining screws just behind the cylinder and weaken them enough for this to work. Id recommend a 1/8" drill bit for this as to leave enough meat in the cylinder for the snapping attack.
