Maximum Security Locking Systems

All BiLock cylinders can retrofit most major manufacturers' heavy-duty hardware. This makes it possible to install BiLock's unequalled security without replacing the existing hardware.  The new "Quick Change" core now offers interchangeable core (I/C) flexibility with the same hardware.  This is the most economical option for high-security and removable core flexibility.  The BiLock "Quick Change" (Q/C) core can be removed from your hardware for maintenance or recombinating  without disassembling the lock!  Re-keying a lock can be as simple as withdrawing one cylinder and replacing it with another cylinder; in seconds!  You can even shift "Q/C" cylinders between different types of locks (e.g., knobs to switch locks, mortise to knobs, switch locks to cam locks, etc.).  Every Q/C core is identical, except for the pinning combination, where required.
