I think you guys are getting a little confused.
VTEC is a system where you can run 2 cam profiles on one engine. VTEC Killer, removing VTEC, or VTEC locking, all mean the same thing.
You take away the ability to run 2 cam profiles (economy/perfomance) and are stuck with just the one profile (performance).
In theory, you could they remove *ALL* of the VTEC hardware, sensors and circutry because you basically just running a simple DOHC motor.
