told straight

If a $40 strike-plate fix solves it, that's what we'll quote, not a new lock. Repairs outnumber replacements on our invoices two to one.

When people call us for this

how the job goes

Four steps, and the price comes first

  1. step 01

    Repair first

    We check whether an adjustment, a new strike or some lubricant fixes it. Often it does.

  2. step 02

    Pick the grade

    If you need new hardware, you choose Grade 2 or Grade 1. Both prices sit side by side on the quote.

  3. step 03

    Install and reinforce

    Every install gets a reinforced strike plate with 3-inch screws at no extra charge.

  4. step 04

    Test and clean up

    We test the lock with every key, haul away the old hardware, and leave the floor clean.

What customers said

Rated 5 out of 5

Storefront lever lockset
“They put the ANSI grade of the hardware on the quote, which no other shop I called would do. Install was clean, and they re-hung the door closer while they were at it without charging extra.”

Broken key extraction
“Half my key snapped off in a 1940s mortise lock. The tech got it out without drilling and talked me out of replacing the lock. Said it just needed graphite. Charged the extraction, nothing else.”

Questions about lock installation & repair

What do lock grades mean?

ANSI/BHMA grades rate how much abuse a lock can take. Grade 1 is the toughest, built for heavy commercial use. Grade 2 is a strong choice for most homes. Grade 3 is the lightest, and we don't recommend it for an outside door.

Can you install a lock I bought online?

Yes. Installing your hardware is $85 to $110 per lock. If the lock is a poor fit for your door, we'll tell you before we start.

Why does my deadbolt stick?

Most of the time the door has shifted and the bolt rubs on the strike plate. That's a repair, not a new lock. We'll adjust it and quote the fix first.
