Why Port Costa Chooses Us
High-Security Keys
Restricted and high-security keys most hardware-store kiosks can't copy.
Mailbox & Padlocks
Small keys too — mailboxes, padlocks, cabinets, and more.
Tested Copies
Every copy is checked so it turns smoothly the first time.
Car Key Duplication
Spare car keys — including transponder and chip keys — cut and programmed.
When to Make a Spare
The best time to copy a key is before you lose it. New home, new tenant, new employee, or simply a backup left with someone you trust — a spare in hand saves an expensive lockout call later.
Why Not Just Use a Kiosk?
Hardware-store machines handle basic keys, but they often produce slightly-off copies and can't touch transponder, high-security, or restricted keys. A Port Costa locksmith cuts to spec and can duplicate the keys those kiosks reject.
Keys We Cut & Duplicate
In Port Costa the common requests are house and apartment keys, office and commercial keys, mailbox and padlock keys, and car keys (including chip/transponder keys and remote fobs). If it opens a lock, it can usually be copied.
