Rekeys & lock changes — know exactly who has a key

Just moved in, had a tenant change, or lost track of who has copies? I’m Ben, the owner of GreenKeys Locksmith. A rekey keeps your existing locks and gives you brand-new keys that work — the old keys no longer do. If a lock is worn, damaged, or you want a different style, a lock change replaces it outright.

I do residential and commercial rekeys and lock changes in Fremont, Newark, and Union City, and planned rekey / lock-change work in Palo Alto and Menlo Park — a strong fit for new homeowners, realtors, landlords, and property managers preparing a property. I focus on these five cities, and I also take work in the cities in between and nearby. If you’re not sure whether I come to you, call and ask.

One visit can rekey a whole home or business. I give honest, flat, accurate quotes — no upsell.

You’ll deal with the owner from the first call to the finished job.

Residential & commercial only — no automotive, no car keys/fobs, no key duplication. Note: I rekey locks; I do not offer a standalone key duplication / key copy service.
