Man, I should have used this locksmith to rekey my doors when I bought my home! I called someone…read morewho had good reviews on Google and it ended up taking forever and costing me a small fortune. Anyway, all of my interior doors are very old and none of them actually close properly. If you push any door when it was in the "closed" position it would simply just open. When I spoke to the other locksmith about this issue he told me I might as well just get all new doors for the time and cost it'd take to get them to shut properly. My mother didn't like that answer so she called Bob. She used him for a lot of work on her own home and when she described the issue to him he said he'd be able to take care of it. He came out and repaired all five problematic doors so they all open and close properly. The best part??? It only cost $100.00!!! If I ever need any future locksmithing, I will be calling Bob. A+ service at a very reasonable cost.

Recently moved into a new home and wanted to re-key all my locks. Called Joe and was able to…read moreconsult via phone to review my existing doors and hardware. Got some bad news (existing owners had two different styles that were incompatible) but was offered some solid solutions.

Other services I called weren't able to fit me in, so I appreciate his willingness to go the extra mile.

I needed a new home re-keyed. I reached out to several well-reviewed local locksmiths via their…read morewebsite contact forms on a weekend so I could get an apples-to-apples comparison. Heard back from Great Valley before 9 AM Monday with a professional quote that was reasonable, so I chose them. On the day requested, the locksmith (Gene) arrived within the window and did the job promptly, expertly and pleasantly. So I am quite satisfied. Oh, the three other local locksmiths? Two never replied. The third apologized when they reached out two weeks later, after the service date.

They were dramatically over-priced, marked up the parts used on my house by about 150% and when I…read moreconfronted them about it they fabricated a "special distributor" who sold high quality parts that could only be purchased by locksmiths. I looked up the parts that they installed and they were the exact same parts by the exact same company as the ones sold at Lowes Hardware. When I confronted them with this information they just tried to convince me that I was mistaken. It wasn't worth a lawsuit, but in my opinion they're dishonest and should not be trusted.
