Yes, there are many locks that, by all intents and purposes, are pick- and bump-proof. However, you will find very few that actually make this claim. Instead, most “pick-proof” locks on the market are labeled as “pick-resistant” due to legal purposes.

The Romans were the first people to come up with the concept of padlocks around 500 BC. They created iron locks with metal bolts that held them closed. Keys were required to open these locks. Basic keys were created by bending metal at 90 degrees, and while this wasn't high-tech, it worked efficiently.

There are three types of locks: mortise, cylindrical, and rim (stem). Nontraditional types of locks provide a higher level of security: multiple bolts, keyless, pad and electromagnetic locks.

Knob locks are incredibly common in Canada and often act as the main security measure for internal doors. These locks are located inside the knob itself, rather than in the door and are opened with a key.
