How would you describe a non distructive entry? I know this will sound silly but is it when drilling is done and sealed completely or is when a lock is distroyed and replaced with another new lock?
the reason i ask is today I did a 7 lever Loudon\Union safe lock and drilled a 4mm hole, picked it open, replaced the lock and sealled the hole completly. Oh, my first safe I opened

The old lock is still intact and working order and I'll use to for practing.
with nde methods is only picking the lock or impressioning
