"The locksmith had to rework the new deadbolt I bought to make it fit the door and rekeyed the existing lower knob lock to make one key work on both locks. It was a longer job but the work was exceptional and amazingly cheap!"

"Whether it’s for your home or your business (I use them for both) one of the contractors you had better have complete trust in is your locksmith. We have been using Surefit Security for over thirty years and couldn't be happier with our experiences. They are extremely knowledgeable and have offered viable and prompt solutions addressing all of our locksmith needs. From replacing hardware and doors to developing and implementing new master key systems in high rise office buildings they have never let us down. The employees who come on site to perform work are professional and courteous and the office staff and owners are always available for consultation when needed. To say that I highly recommend them is an understatement. I really can’t see us ever using anyone else."

"I contacted Colonial on 10/10/13 and the next morning Steve called and came right away in the heavy downpours.  Steve provided Superior service and identified our needs immediately to secure our front door especially with having two small kids. 
Steve is great example of professional and courtesy service and represents Colonial Locksmith very well.  Colonial Locksmith should be very proud having someone like Steve represent their company in the community. 
I would highly recommend anyone in the area that needs a locksmith that will do the job fast and right the first time with a backed guarantee, you can't go wrong. 
Many thanks

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.
