mortise lock

A handy person from Illinois says:
I'm looking for a sliding glass patio door lock - current lever lock shown in attached pics - but I would like to get one with an external key lock if that's an option.

Hello,

Your mortise lock resembles the 82-263 at first glance. See the dimensions from our product page below to confirm that they match up to your part. This mortise is commonly used with handle sets that use the 82-310 key lock. If your external handle came with a key lock or has a cut-out to install one, review the specifications below to be sure that it will work with your original handle. If not, we've related a few standard 3-15/16" hole spacing handle sets on this page that can be used with this key lock. Thank you!
