Frequently Asked Questions

Is the Adams Rite MS1850S handed, or will one lock work on doors sliding either direction?

EASILOK SK4510 is non-handed — one lock works on both left and right opening doors. No need to specify handing when you order.

Can the Adams Rite 4510 be left unlocked for free entry during business hours?

EASILOK SK4510 has a push paddle inside — push to exit freely during business hours, and the deadlatch secures the door when it closes. No key or code needed from inside.

What is the difference between the Adams Rite 4510 deadlatch and a standard deadbolt?

A deadbolt (like SK1850) stays locked until you unlock it. EASILOK SK4510 is a deadlatch — it latches automatically when the door closes, ideal for storefront doors that need to stay shut. Both are keyless and drill-free.

I fired an employee who had keys. What should I do?

Change the code on your EASILOK SK4510 yourself. No $150-300 locksmith rekey fee, no waiting for an appointment.

How do I determine the backset?

Same as Adams Rite 4510: measure center of hole to door edge. EASILOK SK4510 comes in 31/32", 1-1/8", and 1-1/2". TEXT US a photo if unsure.
