This key will work on most Schlage locks found on residential and commercial door-knobs, dead-bolts, and mortise cylinders. This key is cut on an SC1 (5-pin) blank. It will also work on locks using an SC4 (6-pin) blank.
This key is designed so that once inserted into the lock it can never be removed again. As a result, anyone with a previously working key will not be able to use it to open the lock. The lock will only be able to be unlocked from the inside once this key has been inserted.
