Founded in 1967, Chelmsford Lock & Key, Inc. has been part of this community for more than 50 years.

We’ve grown alongside our community, adapting our services to meet the evolving security needs of homeowners, businesses, and institutions.

We’ve worked everywhere from historic homes near Chelmsford Center, where restoring antique lock systems requires delicate precision, to the commercial and retail areas around Drum Hill and Route 3, where modern access control systems are increasingly in demand.

Rekeying is one of the most effective and cost-efficient ways to secure your home.

We install and maintain ADA-compliant door closers, panic bars, fire-exit devices, and other hardware designed to improve safety and meet regulatory requirements. We work closely with business owners to ensure compliance without sacrificing ease of access or aesthetics.

High-Security Lock Solutions

FAQs

1. Do I need to replace my locks if I move into a new home in Chelmsford?
Not always. In most cases, rekeying your locks is the better option. Rekeying allows us to change the internal pin structure of your locks so old keys no longer work, giving you full control over who can access your home. It’s more cost-effective than replacing your locks entirely, and we can usually complete the service in a single visit. However, if your locks are damaged, outdated, or incompatible with modern security needs, we may recommend replacement for added safety.

2. What types of businesses benefit from a master-key system?
Any business with multiple access points or employees can benefit from a master-key system. Offices, healthcare facilities, schools, retail shops, and industrial warehouses often find them invaluable. Master-key systems provide greater security control by limiting access to certain areas while giving management universal access with a single key. This prevents unnecessary duplication of keys and improves both operational efficiency and security.

3. Can you install smart locks for my home?
Yes, we offer installation of Wi-Fi-enabled and keyless entry smart locks for Chelmsford homeowners. Smart locks let you control access remotely, monitor entry activity, and even integrate your locks with other smart home devices. We’ll walk you through the features of each system, recommend the most secure options, and ensure professional installation for optimal performance.

4. Do you offer handicap door opener installation for businesses?
Absolutely. Handicap door openers are essential for businesses seeking to comply with ADA regulations while improving accessibility for customers and employees. We install and service automatic door openers designed for commercial settings and can recommend the best systems based on your building layout and door type. Adding these systems doesn’t just ensure compliance—it enhances customer experience and supports inclusivity.

5. What brands of locks and security products do you carry?
We carry a wide variety of trusted brands, including Medeco, Yale, Emtek, Abus, and others. Whether you’re looking for high-security locks, Wi-Fi-enabled access systems, or traditional deadbolts, we only work with brands known for their durability, performance, and innovation. Our wide selection means we can recommend options that suit every security need and budget.
