Cheap locksmith ads can be useful search shorthand, but the quote must include trip, labor, hardware, after-hours and service details before the technician starts.
Start by asking whether the quote includes the service call, labor, parts, programming, after-hours timing, and taxes. A price-aware locksmith request is about getting the whole number before work begins.
For Bay Area jobs, give city and corridor detail up front. A request near US-101, I-880, I-280, CA-92, CA-84 or the Bay Bridge approach can involve different parking and routing than a quiet residential block.
Do not approve drilling, replacement, or programming because someone says it is the only option. Ask for the reason, the final price, and whether a lower-impact option like rekeying, repair, or a duplicate key is possible.
This guide does not promise a lowest price. It helps callers ask better questions so a cheap-looking ad does not become an expensive surprise.
