Choosing a smart lock that fits your door

Start with the door

A smart lock needs a door that closes and locks smoothly. If you have to lift, push or pull the door to turn the deadbolt, tell me. New hardware does not automatically solve an alignment problem.

Door thickness, existing holes, backset—the distance from the door’s edge to the center of the lock hole—and space around the hardware all matter. Requirements vary by model. I’ll help you check the fit before you order.

Photos that help me advise you

With the door open, send clear photos of:

• The outside of the door, showing the lock and handle together.
• The inside, including the whole lock and any nearby trim.
• The edge of the door, showing the latch, deadbolt and any visible brand markings.
• The frame where the latch and deadbolt enter.
• A wider view if another door, trim or hardware leaves little clearance.

Include your city, what is wrong with the current lock and a link or model number for the one you are considering. You don’t need to take the lock apart for these photos. If measurements are needed, I can tell you what to check.

Choose the features you will use

Think about how you want to enter: a keypad, a phone, a physical key or another supported method. Do you want separate codes for family or visitors? Do you need to control the lock while you’re away?

Check the exact model’s connection requirements. Some locks connect directly to Wi-Fi; others use a compatible hub for connected features. Phone, network and smart-home compatibility vary. Tell me what you already use so we can check the requirements before you buy.

Also check the battery instructions and backup entry method. Know how you would get in if the batteries run down.

Common questions

I already bought a smart lock. Can you install it?

Yes, when it is a suitable fit for your door. Send me the exact model and photos of your existing hardware. I’ll check the fit and discuss any preparation needed before we arrange the installation.

Does a smart lock need Wi-Fi?

It depends on the model and the features you want. Check the requirements for remote access, your phone and any smart-home system before buying. A keypad alone does not tell you how the lock connects.

Can you help with the app and access codes?

Yes. I offer optional app setup, Wi-Fi connection on supported models, access-code programming and instruction. Tell me what help you want so we can include it in the work we discuss and quote.

Ready to plan the installation?

You normally buy the lock; I handle the installation. I check the fit and operation, explain the work and give you a clear written quote before it begins. If the existing hardware needs attention, we can discuss repair options too.

I make planned visits in Fremont, Newark, Union City, Palo Alto, Menlo Park and Atherton. Text me your photos or call (510) 209-8317. Open daily, 9:30 AM–11:30 PM, subject to availability.
