Sliding door handle with key lock

Hello,

Unfortunately, we do not carry any handle sets that use a keylock on the inside, which is against fire code in some places. We do offer a standard keyed handle set like the 82-030A that could work for you as long as the hole spacing and centered thumb latch match your assembly. Just keep in mind that only the external handle will be keyed.

As for adding additional security to the inside of the door, we do offer options such as the 80-006 bar lock. Take a look at this part and a few other options shown in our catalog here.
