Outside lock for door
Hello,
We'd be happy to help but we would need you to write out the distance between the installation hole centers of your handle set, as well as show us the inside handle and mortise lock in the center of the door, to research your replacement options. Thank you!
Thanks for getting back to us. The mortise lock in the center of your door resembles the 82-227, which generally uses a handle set with 3-15/16" hole spacing like the 82-030 shown below. With that being said, your hole spacing looks like it may be larger, so we'll need you to confirm your exact measurement to be sure.
The overall height of the mortise is not as important as the installation hole spacing. You can use the 82-030 handle set as long as the rest of the specifications match up to yours, which is compatible with the 82-310 key lock that is sold separately. Take a look and review the related videos on this page for further assistance.
Since you opted to purchase only the key lock and not a new handle set, keep in mind that you'll need to ensure that your external handle has punch-outs on the inside to install a key lock.
Your original handle also does not have the protrusion that our 82-030 has to support the lock, so you would actually need the 82-315 that comes with a housing to use it in your original handle.
You would only need the 82-315 if you decide to use your original handle set, which appears to be in relatively good condition but would require a key lock housing.
If you opt to replace the original handle set with the 82-030 that we've discussed, then you would use the 82-310 since the 82-030 has a protrusion on the external handle that makes an additional key lock housing unnecessary.
