"Called on Rick Ennis to install double locks on my front and back doors. He came out to install locks under short notice and work was completed in a timely matter - at a very reasonable price. He also specializes in "Access Card" and "Key Control Systems". I'm extremely pleased with his service and will definitely call on him again."

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"I have been on this system for 3-4 years. The initial installation went ok, but the overall functionality and reliability of the system is poor. The basic alarm system works when you manually arm/ disarm it through the app or keypad. However, the alarm cannot be set up on an automated schedule, and NONE of the connected automation features work - lights, outlets, blinds, etc. I purchased the recommended products that the company promised would seamlessly integrate into the system during the sales pitch, but none of them work. They have sent technicians out a couple times but, even after installing bulky repeater boxes in about half a dozen outlets, the system cannot connect. I have submitted several tickets, but Vintage just closes them out and suggests that I self troubleshoot. Alternatively, I can pay for an Automation Maintenance package and they will send a technician out. Bottom line - their system is nothing more than a 1990's alarm with a keypad and phone app. They dont deliver on what they sell, and they try to charge extra for support that should be included."

"I used Lance's Locksmith on my first home purchase in 2003. I recently used them to change the locks on a newly purchased home in 2020. I wouldn't trust any other locksmith. Highly recommend."

"Cheyenne was awesome. I broke off key in my cars trunk lock, did not have spare key. Managed to get broken piece out of lock. Took it to Cheyanne, she McIvyered something with both pieces, cut new keys, cloned chip from original key. Works great,she went above & beyond my expectations. Would patronize there for all my key needs. Great experience"

"Ron Cruz was the technician that came out. I was quoted a much higher price at frist over the phone and wasn't going to use them at 1st. But then they called me back and told me they would charge 1/2. Ron was very professional and friendly. He was also efficient and sympathetic to my situation. I would recommend that you request the tech if given the choice. He even charged my $10 less than the 2nd quote of $60.00 so I wouldn't have to borrow it from my neighbor. I wish many blessings to this remarkable person."

FAQs for locksmith service projects in Dundalk, MD

The installation timeframe varies based on door preparation and lock complexity. For doors already prepared with appropriate holes, installation might take 15 to 30 minutes. New installations requiring drilling take one to two hours. First-time DIY installers should allocate additional time to ensure proper alignment and function. Professional locksmiths complete standard installations efficiently due to their specialized tools and experience.

Most residential doors can accommodate deadbolts, but certain door types present challenges. Solid wood and fiberglass doors accept standard deadbolt hardware, while metal doors require specialized drilling equipment. Hollow-core interior doors lack the structural integrity to properly support deadbolts without additional reinforcement. Doors should be at least 1⅜ inches thick to properly house standard deadbolt mechanisms.

Door warranties remain valid when deadbolts are installed according to the manufacturer's guidelines. However, improper installation that damages the door structure might affect warranty coverage. 

Before modifying any door under warranty, review the documentation for specific limitations or requirements regarding hardware installation. Some manufacturers provide templates or guidelines for acceptable lock placement to maintain warranty protection.

Rekeying offers a more economical alternative to complete replacement when you need to change access, but the lock mechanism remains in good condition. This process involves reconfiguring the internal pins to work with a new key while retaining the existing hardware. For homeowners with multiple locks, rekeying provides the convenience of using a single key for all entry points while maintaining security.
