Is the LockeyUSA 3830 worth it over a keypad deadbolt?

It costs more than many electronic keypads but needs no batteries and has no electronics to fail. Choose it if you want a lock that works in cold, wet or coastal conditions without maintenance.

How many codes can I set?

One user code, with thousands of possible combinations. Everyone who needs access shares that code, and changing it means removing the lock and resetting the tumblers.

It fits standard 2-1/8-inch cross bores and 1-inch edge bores, with doors 1-1/8 to 2 inches thick and an adjustable 2-3/8 or 2-3/4 inch backset. Thicker doors need the Lockey extension kit.

Does it work on exterior doors in coastal areas?

Yes. The marine-grade finishes and Teflon-coated stainless steel interior parts are built for salt air and humidity. Choose a marine-grade finish such as Satin Chrome Marine Grade.

The lock, latch, strike, trim plates and mounting hardware. Check the listing for the finish and whether trim plates are included.
