Client Testimonials

“I purchased a new home, and needed all of the locks changed. Colonial Lock Service came out quickly, and ended up changing the cylinders to help me save money. They did a great job, and were extremely fair and helpful! Would highly recommend this company.”
– Beth T. in New Park, PA


 “The service was excellent. The worker was awesome: polite, courteous, and helpful in explaining what needed to be done.”
– Tom C. in Ellicott, MD


“Great, prompt, and very informative service. I've used different locksmiths in the past, and had the unfortunately common experience of having them change the price when the job is done or halfway done. Colonial charged exactly what they said. It was very reasonably priced, and the locksmith was great about pointing out where things could use adjusting, and making the adjustments. Very professional, courteous, and reasonable.”
– Michael W. in Glenwood, MD


“The locksmith was the nicest hired contractor I've ever met. He was so patient, and did a great job installing my keypad lock and making sure it worked.”
– Camille B. in Germantown, MD
