The average cost of rekeying a house ranges between $100 and $450, depending on the number of locks, type of locks, and service fees. Rekeying is recommended when you move into a new home, lose your keys, or want to improve your home’s security.
Most people don’t think about home security until there’s a legitimate reason, such as losing keys, moving into a new home, or encountering a potential security threat.
With years of experience in residential locksmith services, we’ve noticed that one of the most common questions homeowners have is how much it costs to rekey a house and when they should do so.
Rekeying is one of the most cost-effective, quick, and efficient ways to secure your home without replacing all of your locks. This guide will teach you everything you need to know about rekeying costs, when they are necessary, and how to make the best decision.

This prevents anyone who previously had access from entering your home.
