FAQ

Mailbox Locks — frequently asked questions

What makes mailbox locks in California — Los Angeles, the Bay Area & Silicon Valley different from other locksmith services?
Mailbox Locks requires the right tooling, the right parts on the truck, and the right experience to do it cleanly the first time.

Cluster mailbox, USPS-approved replacement, and curbside mailbox locks — fast and affordable.
Can a locksmith change a USPS cluster mailbox lock?
Yes — that's exactly what our mailbox locks service is built for. USPS-approved 4C and CBU compatible cylinders, and two new keys per mailbox. Our California — Los Angeles, the Bay Area & Silicon Valley dispatcher will confirm pricing and timing before sending a technician.
Should I rekey or replace my locks when I move into a home in California — Los Angeles, the Bay Area & Silicon Valley?
Most homeowners in California — Los Angeles, the Bay Area & Silicon Valley are best served by rekeying. As long as the existing locks are in good condition and you like how they look and feel, rekeying is faster, costs less, and is just as secure as buying brand-new locks — every old key (sellers, agents, contractors, neighbors) is invalidated. We'd recommend full replacement instead if the locks are worn out, builder-grade, or you want to upgrade to high-security or smart hardware.
Can One & Only Locksmith match all the locks on my California — Los Angeles, the Bay Area & Silicon Valley home to one key?
Yes. As long as the locks are compatible (same keyway/family), we can rekey every door — front, back, side, garage entry, mailbox, and even patio locks where applicable — to operate from a single key. If your locks are mismatched brands, we can swap a few cylinders so the whole house can be keyed alike.
What's a smart lock worth on a California — Los Angeles, the Bay Area & Silicon Valley home?

Are smart locks safe to use as the main lock on a California — Los Angeles, the Bay Area & Silicon Valley home?
Yes, as long as the model is reputable (Schlage, Yale, August, Kwikset Halo, Level), correctly installed, and supported by a strong door, frame, and strike plate. We recommend pairing a smart lock with a reinforced strike plate and 3-inch screws into the king stud. The weakest link in most break-ins isn't the lock — it's the strike, frame, or door.
