New Carrolton, MD Locksmith Services and Security Systems 

Since 1960, Ernie’s Lock Company, Inc. has been the neighborhood locksmith for New Carrollton, Maryland. Our brick-and-mortar shop is a favorite stop for new home or condo owners, with its quick, 10-minute drive from the town once simply called Carrollton.

The History of New Carrollton

Carrollton claims its name from Charles Carroll, one of the signers of the Declaration of Independence. Charles Carroll signed his name as “Charles Carroll of Carrollton.” The name caught on after that, with more than 10 states naming counties after him. So — how did Carrollton become New Carrollton?

Maryland had two towns named Carrollton. While a coin toss was tempting, a voter referendum was held instead and approved changing Carrollton to New Carrollton in the 1960s, shortly after Ernie’s opened.

Like New Carrollton, we’ve been flexible with our name. Customers call us Ernie’s, Ernie’s Lock Company or simply the locksmith on Queensbury Road, straight down from the Rite Aid.
