lock set / handle set New Castle XT Sliding Patio door

A home owner from CA says:
Issue with our door: keyhole is insanely tight and it's getting worse and worse to the point that I feel like the key is gonna break

So I'm looking to replace the key hole on it or the entire handle set

Please advise for the right part number.

Hello,

Your mortise lock resembles the 82-238, which is commonly used with the 82-081 keyed handle set. Review the dimensions below to confirm they match up to your hardware. If so, you should be able to use the 82-310 key lock that comes with the 82-081 for your repair. Before ordering, I would recommend removing the handle and testing the mortise lock with a slotted screwdriver to determine if that part is working properly. Thanks for posting!
