Professional lock manufacturers like Medeco, Schlage, Miwa, Assa and Kaba all created their own version of bump-resistant or bump-proof locks.

If an attempt is made on a lock that has shallow drilled pin stacks, the bump key will be unable to bump the shallow drilled pins because they are too high for the bump key to engage.
