"Eli arrived punctually after calling to alert me of his arrival. Once here, after hearing the problem, he looked at the door and realized the problem was that the door had settled low. I didn't need new locks, as I had thought; instead, he simply fixed the door so the locks fit correctly again. Instead of having to pay for new hardware, I was only charged for the visit and 15 minutes of time."

"Overall rating = 5 stars. Raanan and his wife, Hanna, of “Raanan the Locksmith,” completed my job on Friday, July 17th. Their service was excellent, professional, friendly and courteous. They fixed my locksmith problems on my front and back doors in record time. I highly recommend them to anyone who might have locksmith issues. I will certainly call them again should I have the need. Please keep this company on your list for future referrals."

"Juan arrived a bit later than expected but got to work and did the jobs, running to Home Depot for needed parts which I didn't know we needed. He explaned things to me and knew what he was doing. He did all the jobs I outlined and left with everything working. He was cooperative in pointing the kitchen track lights where I wanted the to shine. He then looked at the plumbing job (vanity install) and realized that the vanity I bought wasn't a feasible option because of the direction of my pipes (to the side and not the back) therefore needing to go right through the drawers! I have returned the vanity to Home Depot! He didn''t waste time talking to me but did talk to himself (or on his phone ) while he worked! He cleaned up his dust and debris well, Satisfied with his cost which really should have been higher when I thought about it later. I would use him again if he was from near Frederick, but he came from Baltimore! I'd rather use local tradesmen...."
