Smart locks

Smart locks, set up so they actually work

Smart locks mostly fail for one reason: a door that doesn't line up. We check the door first, install the lock, set up the app with you, and wipe the factory codes before we go.

told straight

A smart lock on a misaligned door is a $300 doorbell. If your door needs adjusting first, that's a line on the quote, not a surprise on the invoice.

When people call us for this

how the job goes

Four steps, and the price comes first

  1. step 01

    Door check

    We test how the bolt lines up with the frame. A smart lock's motor can't push a bolt that rubs.

  2. step 02

    Install

    We fit the lock and a reinforced strike plate, then test the bolt by hand and by motor.

  3. step 03

    App and codes, with you

    We set up the app on your phone, add your codes, and delete the factory codes.

  4. step 04

    Backup drill

    You practice the backup key and a battery change before we leave.

What customers said

Rated 4 out of 5

Smart lock install
“Great work, honest price, and they wiped the factory codes in front of me. Four stars only because the arrival window was 2 to 4 and they rang at 3:50. They did call at 3 to warn me, which I appreciated.”

Questions about smart locks

What happens if the battery dies?

Every lock we supply has a physical key backup, and most warn you weeks before the battery runs low. We show you both before we leave.

Which smart lock should I buy?

Pick one with a physical key backup, a Grade 2 rating or better, and an app log of who came and went. Tell us the model and we'll say whether it fits your door.

Can you install a smart lock I already bought?

Yes. Installing and programming a lock you bought is $145 to $185, door check included.
