Frequently Asked Questions About Residential Lock Changes

Q1: How often should I consider changing the locks on my home?

A1: It’s generally recommended to change your locks when you move into a new home, after a break-in or security concern, if your keys are lost or stolen, or if your existing locks are old and showing signs of wear. For optimal security, consider a full lock change every 5-7 years, or as needed.

Q2: What is the difference between rekeying and changing locks?

A2: Rekeying involves changing the internal pins of a lock cylinder so that a new key works, while the old key no longer does. Changing locks means replacing the entire lock mechanism. Rekeying is often a more cost-effective solution if the existing lock hardware is in good condition.

Q3: What types of locks do you recommend for residential use?

A3: For robust security, we highly recommend deadbolts, especially those with a long throw bolt and a hardened steel strike plate. Smart locks offer convenience and advanced features, while traditional knob and lever locks are suitable for interior doors. We can assess your specific needs and recommend the best options.

Q4: How long does a typical residential lock change take?

A4: The time required for a residential lock change can vary depending on the number of locks, the type of locks being installed, and any unforeseen complications. However, for a standard lock change on an average-sized home, our experienced technicians can often complete the job within 1-3 hours.
