Replacement for atrium door

A home owner from Defiance Missouri says:
This lock is over 20 years old - needs replacing as won't stay shut . The only markings I can find is Jado on top of handle and weather shield logo above handle . The one I ordered is different and won't work. The lock part is longer and skinnier on my old one . Any ideas ? Thank you Denise

Hello there. I believe this might be our 82-400 Atrium Lockset, but you'll need to compare all the dimensions listed below with your old hardware. Let me know if anything differs, and if so, by how much.
