The Easiest Way to Upgrade Your Adams Rite MS1850S to a Keyless Smart Lock (No Drilling Required!)

If you own a small business in the U.S.—whether it’s a bustling restaurant, a local grocery store, or a boutique shop—you likely have a standard aluminum storefront door. And if you look at the side of that door, you’ll probably see the industry standard: the Adams Rite MS1850S mortise lock.

While these locks are durable, they come with a major headache in 2026: Physical Keys. ### The Hidden Costs of Traditional Storefront Keys Managing keys for a rotating team of employees isn't just annoying; it’s a security risk.

• Lost Keys: A single lost key means calling a locksmith, which can cost anywhere from $200 to $450 for an emergency visit.
• Employee Turnover: Every time a manager leaves, you have to rekey the entire cylinder.
• Late Night Lockouts: Getting a call at 2 AM because someone forgot their keys is a nightmare every owner wants to avoid.
