Your definition is correct, but your are mis-interpreting it. The key word is "neutralize," which means that the security of the cylinder is null and void. During lockpicking, the cylinder's security is your obstacle. In bypass it is not, because you are neutralizing/bypassing it altogether.

Mcm,
I'd like to remove 'intended authentication, usually a key or combination' because this is irrelevant in context (lockpicking too does not need either). Bypass is unique because it is an attack against non-cylinder portions of the lock, namely actuator or bolt (While it is right to include latch I don't think it is necessary; makes it a bit wordy). We also have "a bypass occurs" a few too many times, and the ending is a bit wordy if we include surreptitious (eventually I'd like to have the NDE page like to covert/s.e anyways...). Here's my proposed change:
"A bypass occurs when a lock is compromised without affecting the integrity of the lock cylinder. Generally, the bolt or actuator are targetted, though in some methods a knob or handle on the rear of a door is manipulated to allow entry. Bypass takes many forms, and can be either non-destructive or destructive depending on the techniques used."
