What is bumping?
In a bump attack, a specially cut key is inserted into the lock and struck with a hammer. The impact briefly forces the pins into a neutral position, allowing the lock to turn. An average standard cylinder can be opened this way in 5–15 seconds — without leaving any trace.
What is picking?
Picking requires two tools: a tension wrench and a pick. The burglar feels out the pins one by one and sets them at the shear line. More complex cylinders take longer, but standard models can be opened by a practised picker in as little as 30 seconds.
How do you protect yourself?
Anti-bump and anti-pick protection is built into certified security cylinders. They use special pin geometry, false pins, magnetic pins, or rotating elements that neutralise these classic techniques. Choose a cylinder certified to SKG***, AIS, or the Mul-T-Lock standard.
