About Us

700x450Masters Safe & Lock began serving Maryland businesses and residences in 1983 operating as D&D Safe & Lock.  In 2004, D&D Safe & Lock downsized and became Masters Safe & Lock, Inc.  Owner Dave Griffin still owns and operates Masters Safe & Lock.  Dave’s simple philosophy is still, as it was in 1983; RELIABLE SERVICE AND REASONABLE RATES.

Our knowledgeable and experienced staff is ready to help you with your security needs, from simple openings and re-keying to safe and vault openings and repairs in Frederick, MD and surrounding areas including Urbana, Middletown, New Market, Mt. Airy, Brunswick, and Walkersville.  We also serve the entire Frederick, Washington, and Baltimore areas.  You can count on quality service at reasonable rates.
