Which Keyless Entry Option Is Right for You?

Start with how you want people to enter and how you want to manage access.

Mechanical Code Locks

A good fit for straightforward code entry.

Unlock with a code, without batteries, wiring, Wi-Fi or an app. Choose this option when you want simple access without electronic features.

Battery-Powered Smart Locks

A good fit when you want more entry options.

Available features include codes, fingerprint entry, keycards, facial recognition and app management, depending on the model. Keycards can make entry easier for people who prefer not to enter a code.

These locks need battery replacement. We help match the model to your door or gate and the features you need.

Where We Install Them

Home doors, pedestrian gates, apartment mailbox areas and pool entrances. The right lock depends on the entrance, its exposure to weather and how people will use it.

Send us photos of the entrance and existing lock, plus a short description of who needs access and which entry options you prefer.

Apartment Mailbox Security: Three Areas, Controlled Access

The apartment community was dealing with unwanted visitors and mailbox break-ins. Its three mailbox areas were open, allowing people to walk directly up to the mailboxes.

Duncan’s Services built and installed custom security gate enclosures for all three areas, adding keyless entry to help restrict unwanted access while keeping everyday entry convenient for authorized users.
