"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."

"Amazing, amazing, amazing! Y’all it’s 1:30 in the morning and I locked my keys inside of my car. There were just sitting in the passenger seat under one of the Christmas presents I bought. I could literally see the keys but couldn’t get to them. I called 3 other companies who were supposedly 24 hour locksmiths but they weren’t able to send someone out until 8am. But then I called Locksmith on duty. They answered quickly and someone came out to my location in less than 20 minutes. They verified my identify, popped that lock and I was good to go. And on top of that it was only $95. Other places always try to get over on you with this fee and that hidden fee. But Alex was straight forward about their pricing. I hope I don’t find myself in a situation where I have to call them again lol. But if you lock yourself out of your vehicle and need some help quickly, no matter the time, call Locksmith On Duty. They’re be there ready to serve you and at a reasonable price. ? Goodnight y’all."

"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 Baltimore, 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.
