How Frederick’s Home Ages Affect Rekeying
Frederick’s median home construction year is 1994; 40% of homes were built since 2000, while 32% were built before 1980. That range means lock age and condition can vary from property to property, so a home’s construction date alone cannot tell us whether its locks can be rekeyed. With 56% of homes owner-occupied and 31% detached single-family, it helps to identify each entry door you want included; the number and condition of the locks shape the job more than the home category.
Frederick Locations to Mention When You Call
Frederick is in Frederick County, and local roads include I-70, Frederick Freeway, US-40, US-15 and US-340.

If you’re in Whittier or Linden Hills, naming the neighborhood can also help clarify where you need the rekeying.

Frequently asked questions
What do you check first when rekeying a lock in Frederick?
We inspect the locks you want changed, including their condition and whether they’re suitable for rekeying. We also confirm which doors you want included so the new key plan matches your needs.

Yes, we can assess locks at homes of different ages, but the home’s construction year by itself does not determine whether a lock can be rekeyed. Frederick’s housing includes homes built before 1980 and homes built since 2000, so we check the actual locks on site.

Yes. MD Locksmith is open 24 hours a day, 7 days a week, and our mobile locksmith comes to you for on-site service in Frederick.
