"I contacted Doorbusters Lock & Key for rekeying several locks at my home, and they were excellent from start to finish. The technician arrived quickly, was professional and polite, and rekeyed everything perfectly. All the locks work smoothly, and the price was fair and exactly as quoted. I really appreciate how efficient and honest they were, definitely a company I’ll call again for any locksmith needs. Highly recommended!"

"Wonderful. Returned my call shortly after I reached out through Angie's List, came out that same day (a Sunday no less!), and had the work completed with in short amount of time. Replacing a door knob and dead bolt sounds like an easy proposition, but this really wasn't. I had tried and failed several times finding hardware that would work in the undersized holes and decided I needed to use a professional. Good decision."

Start by searching a trusted directory for locksmiths in your area and reading recent customer reviews. Confirm that each candidate holds state-required licenses, maintains active insurance, and is a member of professional groups such as ALOA. Before you schedule, ask for a written estimate, proof of credentials, and references. Finally, verify the company’s physical address (not just a P.O. box) and check that the technician arrives in a marked vehicle and uniform.
Door locks must be replaced immediately when key security is compromised. Replace your locks when moving into a new home, after any burglary or attempted break-in, or when you lose a key that reveals your address. This practice strictly prevents unauthorized access and maintains a secure environment by ensuring that only trusted individuals have access to your home.
Rekeying a lock requires 10 to 15 minutes per unit when performed by a skilled professional. This efficient process resets the lock’s internal pins to work with a new key, rendering all previous keys ineffective. Rekeying offers a fast and secure solution that enhances your home security without disrupting your daily routine.
Security starts before the locksmith turns the first screw. Ask the dispatcher for the technician’s name, company ID, and arrival time, then confirm that information at the door. Once the job is done, request an itemized invoice and test every repaired lock yourself. Keep any old hardware or keys the professional removes and ensure they are either left with you or destroyed, so no surplus keys are left behind.
