Commercial Lock Replacement

Businesses face unique lock challenges including high traffic wear, compliance requirements, and the need for consistent access control. Zentrova Locksmith replaces commercial locks of every grade, from standard office lever sets to heavy duty mortise locks and panic hardware on fire exit doors.

After a break in attempt or vandalism, immediate lock replacement is essential. Our emergency locksmith service handles urgent commercial replacements around the clock so your business is never left exposed.

When to Replace vs Rekey

Not sure whether you need a full replacement or a simple rekey? Our technicians assess the condition and security level of your existing hardware and provide an honest recommendation. Rekeying is ideal when the lock body is sound but you need new keys. Replacement makes sense when hardware is physically damaged, outdated, or you want to upgrade to a higher security grade.
