Lockstar Locksmith

307 S. Ingram Ct.

Middletown, DE 19709


We are a local, family owned locksmith company located in Middletown, Delaware. Lockstar offers professional and affordable residential, commercial and auto locksmith services. We are knowledgable and have many years of experience in the locksmith business.

We are up against many competitors that are not who they say they are. They advertise in Delaware with a 302 area code but are actually located in PA or MD. Other companies have many phone numbers or listings to make it seem like they have an office in different parts of the state.

We are what we say we are. Located in only one place...for now. If we cannot get to you in a timely manner we will say so and give you an appropriate time frame. If you need a locksmith immediately and we cannot service you, we will say so and refer you to another locksmith that may be able to help you.

Our goal is to have our customers become our best ally. We will provide excellent service at reasonable prices. It is our hope that our customers will refer us to their friends and families that may need our services.
