CS Lock Sliding Glass Patio Door Handle Lock Set Mortise Type B-Position Off Center Latch Keyed, Brushed Chrome

Originally sent the wrong set, which was probably a manufacturer error, and Countryside sent me a correct set with a label for return shipping. Countryside
Was easy to deal with, and quickly sent the lock set I could install right away

Nice looking and good quality.

Sturdy and substantial patio door lock great fit and finish, but my problem came when trying to get duplicate/spare keys for family members. No Lock Smith has been able to make a functional duplicate key? It does come with two keys, but if you should need more keys, you will be out of luck like me.
P.S. emailed Countryside Locks and did not receive a response😒
