Does the paper roll trick work on any key laptop lock?

The video above demonstrates that a Kensington lock can be picked with a paper roll. Other videos suggest it only applies to the Microsaver Kensington lock. Is this a flaw that is apparent to all laptop lock using keys or just that one model? Can I safely use my off brand Certified Data key laptop lock without worries of this flaw applying to my lock? Also, it uses a round type key with multiple drilled depression on the side.

Locks are for honest people. FACT!

Nothing is ever safe IF someone wants it. I have never tried this - or wanted to - Assume it works on ALL of this type of lock to be safe. - covers a lot of D type bike locks as well.
