FAQ

Locksmith in Diamond Bar: common questions

What people ask before they call. If your question isn't here, the dispatcher will answer it on the phone.

Are you a local locksmith in Diamond Bar, or a call center?

One & Only Locksmith runs one dispatch line, (888) 492-0666, that schedules its own mobile technicians across greater Los Angeles. The dispatcher who answers takes your address and the problem, assigns the technician covering the San Gabriel Valley, and tells you the ETA before anyone is sent. The same number reaches dispatch for updates while you wait.

Do you cover every ZIP code in Diamond Bar?

Yes. Diamond Bar is dispatched as part of greater Los Angeles, and that covers ZIP code 91765. Addresses just over the city line in Walnut, Pomona and Rowland Heights are handled the same way. If your address sits on a boundary or is hard to find, give the dispatcher the nearest cross street.

Will you damage my lock or door?

Non-destructive entry comes first: picking, bypass tools and decoding, which leave the lock working as before. Drilling is a last resort for hardware that cannot be opened any other way, and the technician explains why and gets your approval before doing anything irreversible. If a lock does have to be drilled, it is replaced in the same visit where the hardware is standard.

Do I get a price before any work starts?

Yes. The dispatcher gives you a range on the phone once they know the lock, door or vehicle, and the technician confirms a written quote on site before starting. If you decide not to go ahead at that point, you say so then. You receive an itemized receipt when the work is done.

What payment methods do you accept?

Cash, Credit Card, Debit Card, Apple Pay and Google Pay. The receipt lists what was done and which parts were used, which is what landlords, property managers and insurers usually ask for.

Is there an extra charge for nights, weekends or holidays in Diamond Bar?

Ask the dispatcher whether an after-hours charge applies to your address; you'll know before anyone is sent. The line itself is answered around the clock, every day.
