Can You Add a Smart Lock to an Older Door? Here’s What Phoenix Homeowners Need to Know

Smart locks are a top upgrade for home security and convenience—but many Phoenix homeowners wonder: Can I install one on my older door without replacing it? The answer is usually yes—with the right lock and a few small adjustments.

At Affordable Security Locksmith And Alarm, we help homeowners modernize their entry points while keeping their original doors intact. Check out our residential locksmith services or read below to see how smart locks can work with your existing setup.


🏠 What Counts as an “Older Door”?

Older doors in Phoenix are often found in:

  • Mid-century ranch homes
  • Historic districts (like Willo or Encanto)
  • Custom homes with unique or vintage door hardware
  • Homes built prior to 1995 with non-standard boreholes or lock sizes

Even if the door is solid wood or metal, that doesn’t mean it can’t accept a smart lock—it just may need a little adjustment.


🔧 Yes, You Can Add a Smart Lock to an Older Door—Here’s How

1. Match the Existing Borehole Size

Most smart locks are designed to fit a standard 2 1/8″ borehole. If your door is older, it may need:

  • A slightly larger hole drilled
  • An adapter plate for non-standard lock spacing

Our team can modify and install without damaging the door’s appearance.


2. Check the Backset (Distance from Edge to Center of Hole)

Most locks are adjustable to fit 2 3/8″ or 2 3/4″ backsets, but older doors may fall outside that range. We’ll measure and select a model that fits your hardware placement.


3. Inspect Door Thickness

Some older doors are thinner or thicker than modern smart locks are designed for. Many brands offer extension kits or slim designs that work well.


4. Consider a Retrofit Smart Lock

If you want to keep your original deadbolt and just add tech features, some smart locks (like August Smart Lock or Level Lock) install on the inside only—leaving your exterior hardware unchanged.


5. Check for Wi-Fi and Power Accessibility

For full smart features (remote locking, app access, voice control), ensure the door’s location has good Wi-Fi access and batteries can be changed easily.
