Fair Locksmith Pricing and Friendly Service

Providing upfront, transparent pricing is one of our main priorities at Ernie’s — and one of the reasons why we’ve been able to develop long-term relationships with residential and commercial customers. While other commercial lock installers may quote a lower price initially, it’s not uncommon for the final bill to add on surcharges, hidden fees and other surprises. At Ernie’s, we take the time to explain all of the work we do and its associated costs. That way, when you receive your final bill, there’s no last-minute sticker shock — just a fair price for a job done well.

Our Maryland & D.C. Lock Service Areas

On-site home and lockout services are available throughout Prince George’s County, including Hyattsville, College Park and nearby municipalities. Keeping our service area local allows us to respond faster in the event of an emergency. It also means we have a detailed understanding of all neighborhoods we work in, and can recommend an appropriate security system in more dangerous areas.

As commercial work is our specialty, we are able to provide high-security door locks and other advanced systems for a wider range of customers. Call us to inquire about commercial lock service in Bowie, Towson, Crofton and beyond. No job is too big or too sophisticated for our team.
