We had an amazing experience with this local, truly family-owned security company- N&D Security. So…read morewhen you call the company, owners Son-Mom duo (Perry & Sally) are going to pick up the phone. From the very first call, they were friendly, knowledgeable, and made us feel comfortable choosing them. There was no upselling, in-fact Perry convinced me to drop some unnecessary equipment (which would have otherwise added to the invoice price). The installation went smoothly, and the team (David, Nathan and John) took their time to explain everything clearly and answer all of our questions. What really sets them apart is the support after the installation. Anytime we've had a question or needed help, they've been quick to respond and genuinely happy to assist. The owner, Perry, dropped by a couple of days after installation to help us out on an issue. It's rare to find a company that truly cares about their customers the way they do. It feels great supporting a local family business, and we feel much safer in our home because of them. We did thorough due diligence for a couple of months and are happy to work with N&D Security. Please don't consume your time in unnecessary google searches, look no further and select N&D Security for all your security needs. We highly recommend this company to anyone looking for reliable, honest, and top-quality security service. Thank you N&D Security family from Chaudri family.

He asked for pictures of the lock and door jamb and gave me some diagnostic tests, all so he could make sure he knew what the job would entail and make sure he had the right tools. The job overall took him about 2 minutes, but he double checked everything before starting work and flagged a few items I should look out for in the future. To boot, he's a lovely guy with a very interesting background with a ton of specialized knowledge and training. I will absolutely call him for my next locksmith needs.

One of the door locks was already broken (to be exact: part of it was missing) when I bought the condo years ago. I asked the locksmith recommended by my realtor to come and fix it, only to be left without any follow-up and explanations, probably because he could not think of any solutions to a discontinued antique lock. That was very disappointing. Recently, I found Jair. I decided to give him a call after reading all the good reviews about him online. He responded quickly, came and inspected thouroughly, and explained to me the issue in details patiently. The most important thing is that: he was willing to figure out a solution to this difficult situation. He made an effort to source a new lock which is compatible with all the dimensions of my old lock. He also provided options for me when it came to pricing. Eventually I picked a pricier lock as I think it is worth investing. At the end, the problem was solved nicely at a reasonable price and within a short time frame. He even gave me additional advice on my door when he spotted that the door looks misaligned. I rarely write reviews, but I hope my experience can help home owners in Bethesda know who to reach out if they have similar problems.

That's pretty much what you want. As for "it just works," the Alarm.Com system and equipment they are a dealer for really gives you peace of mind. It's actually secure.
