"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!"

"Despite a hiccup with scheduling, AA Lock & Key was professional, cost-efficient, and great to do business with. I had the pleasure of working with the owner, who even went above and beyond the call of duty by helping me a door that was jamming when we tried to close it. He kept me abreast of everything he was doing, made me test his work while he was there, and all-in-all proved that the hiring of AA Lock & Key was a good decision. Should we need a locksmith in the future, I will be hiring them."

"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."
