Replacement lock with keys

A quick learner from USA says:
Hello,
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

Regards
David

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.
