Change door locks after moving, a breakup, or a security concern. Before we open any home, unit, or vehicle, we confirm that you are authorized to enter.

Being a mobile locksmith in Foster City means we are part of the community we serve. Word travels fast here, and we would rather earn a lasting reputation for fair, careful work than chase a quick dollar. That mindset shapes every job.

How our Change Locks works in Foster City
When you book change locks in Foster City, you can expect a clear, step-by-step visit:
Discuss goals: We learn why you want the locks changed.
Choose the path: Rekey for speed or replace for new hardware.
Perform the change: We complete the work and hand over keys.
Test: Every door is checked before we finish.
Throughout the visit we keep you in the loop. Before we touch anything on your Foster City property, you will know what we found, what we recommend, and what it will cost — so there are never surprises when the work is done.
We come prepared. Our Foster City service vehicles carry the blanks, cylinders, programmers, and hardware for the vast majority of jobs, which is why we can usually finish in one trip instead of scheduling a return visit.
What you get with Avant Guard Locksmith
Choosing a locksmith comes down to trust, and trust is earned by being clear and doing careful work. In Foster City, Avant Guard Locksmith focuses on both: we tell you what we see, what your realistic choices are, and what each one involves, then we let you decide.
We would rather do the job right than do it twice. Taking a few extra minutes to align a door, clean a cylinder, or verify a key programs correctly is the difference between a fix that lasts and a callback — and our Foster City customers notice.
Skill matters, but so does judgment. Knowing when to rekey instead of replace, when a lock can be repaired, or when a security upgrade is genuinely worth it saves Foster City customers money — and that judgment is what we bring to every visit.
- Respect for your time — we aim to arrive when we say and finish efficiently without cutting corners.
- Broad capability — one call covers residential, commercial, and automotive lock and key needs in Peninsula.
- Care for your property — we favor non-destructive methods and protect doors, vehicles, and finishes while we work.
- Straight talk on options — we explain whether a repair, a rekey, or a replacement makes the most sense before we start.
- Clear communication — you hear the plan and the pricing before any work begins, so there are no surprises.
