This knob lock is durable enough to fit a regular commercial type door, and the finishes are attractive enough to install on any residents.
The BiLock locking system is one of the most secure locks made in the world. Most standard locks use a 5 or 6 pin system with top and bottom pins, making them susceptible to lock bumping and unauthorized entry. BiLock patented lock system uses 12 bottom pins and one trigger pin. The key required to operate this lock is U-shaped, with six cuts on each side of the key and a trigger mechanism as part of the key. The lock cylinder has a dual sidebar locking system and uses only bottom pins, making it bump proof.
Another feature of the BiLock high security lock system is the patented key design. Bilock keys cannot be made on any ordinary key machine, such as the kind you would see in the hardware store. In order to make a BiLock key, two proprietary key machines are required. Only authorized BiLock dealers have these key machines. This prevents unauthorized key duplication.
