Replacement lock with keys

A quick learner from USA says:
I need the lock and keys only for my Atrium doorset.
Can I purchase this from your company?
The lock set is one of your old ones from the late 80's

Thx in advance for your assistance

We do carry the 40-123 key cylinder, which I think could work with your handle set, but you would need to get a longer set screw to match the length and thread count to secure the 40-123 . Your best bet might be to go to a locksmith in your area to have them re key your existing lock.
