FAQ

1. What does the Ozi-1 combination lock actually do?
   The Ozi-1 system combines an internal snib, and double-cylinder deadbolt in one unit, so you can use the handle normally, snib it from inside, or fully deadlock the door with a key.

2. How do I know if I need the left or right hand version?
   Simply click on the Handing Information image to confirm. Stand on the inside of your doorway, if the hinges are on the left hand side, you require a left hand model and if they're on the right hand side, you require the right hand model.

3. Is everything I need included in the kit?
   Yes, the set includes the knurled lever on longplate, Australian-made mortice body, standard striker kit, double Euro cylinder, and 3 keys, so you don’t have to source separate components.

4. Can this lock be re-keyed by a locksmith?
   Yes, the double Euro cylinder can be re-keyed or keyed alike by your locksmith so it can match your existing key system if required.

5. Is the black finish durable?
   The finish is backed by a 12 month limited guarantee when installed and maintained according to Nidus guidelines, and the lock mechanism itself is covered by a 10-year limited mechanical guarantee.
