There are several factors important for a successful bump key, here are a few that come to mind:
- number of pins in the lock
- spacing between the pins
- height of the pins in rest
So a 5 pin bump key won't work on a 6 pin lock, regardless if the profile fits the key way.
If the pins are not on the same locations as the bitting in the key, then you are going to have a hard time bumping it.
I've seen locks where the pins in rest hardly reach the half of the keyway and I've seen others that reach almost to 3/4 of the key way.
This will also influence the bump keys working on a lock.
So your statement is not correct
