Our Story

Built on One Simple Promise

Anyone who has been locked out in Los Angeles knows the story: you search online, call a number that promises "$19 service," and the person who arrives has no company name, no license, and a bill four times what you were quoted.

David Ham and Jay Hahn spent years in this industry watching that happen to their own neighbors in Koreatown. Green Locksmith LLC exists to be the opposite: a real shop with a real address on West 8th Street, a real license, and a price that doesn't change between the phone call and the invoice.

Over 18+ years the work grew from locks and keys into full door and frame carpentry, storefront hardware and tenant improvements — because customers kept asking, and because a locksmith who can also rebuild the door solves the whole problem instead of half of it.

The Owners

Who You'll Be Working With

David Ham — Co-Owner

David handles most emergency dispatch and residential work. He's the voice you'll usually hear at 2 AM, and he's the one who insists every price be stated before a tool comes out of the truck. Fluent in English and Korean.

Jay Hahn — Co-Owner

Jay leads the commercial and contractor side: master key systems, storefront hardware, door and frame replacement, and tenant improvement projects. If your job needs a written scope and a bid, Jay writes it.

How We Work

Four Rules We Don't Break

The quote is the price

You approve a flat price before work starts. No mid-job surprises, ever.

We identify ourselves

Company name, license and ID shown on arrival. You always know who's at your door.

Least damage first

Non-destructive entry is always attempted before any drilling — and we explain why if it isn't possible.

We come back

If something we installed doesn't work right, we return and fix it. Parts and labor warrantied.
