If your situation is not on this list, do not worry — it simply means it is a little less common. Call Avant Guard Locksmith at (408) 755-3415, describe what is happening in Fairfax, and we will tell you honestly whether it is something we can resolve on site.
Many of these problems share a root cause — wear, misalignment, a worn key, or a security event like a move or lost key. Part of our job in Fairfax is finding that cause so the fix holds instead of masking the symptom.

- Ending a shared living situation
- Old locks you no longer trust

How our Change Locks works in Fairfax
We keep change locks simple for Fairfax customers. A typical job follows these steps:
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.
If we discover something unexpected mid-job — a hidden alignment problem, a worn part, a vehicle quirk — we stop and explain it before proceeding. You always stay in control of the decision and the budget.
Throughout the visit we keep you in the loop. Before we touch anything on your Fairfax 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.
What you get with Avant Guard Locksmith
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 Fairfax customers money — and that judgment is what we bring to every visit.
A lot of security problems get worse when they are patched instead of properly fixed. Our Fairfax technicians take the time to correct the underlying issue — an alignment problem, a worn cylinder, a mis-programmed key — so you are not calling again next month.
Choosing a locksmith comes down to trust, and trust is earned by being clear and doing careful work. In Fairfax, 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.

- Mobile-first service — we come to you across Fairfax and Marin County, so there is no towing your car or hauling hardware to a store.
- Straight talk on options — we explain whether a repair, a rekey, or a replacement makes the most sense before we start.
- Care for your property — we favor non-destructive methods and protect doors, vehicles, and finishes while we work.
- Local coverage — we serve Fairfax and nearby communities like San Anselmo, San Rafael, and Ross, so help is rarely far away.

During change locks, we protect the surrounding area — the door, the paint, the vehicle trim — and work methodically. When we finish, we test everything, hand over your keys, and make sure you know how to keep the hardware working smoothly.
So what actually happens when we arrive? First, we confirm the problem in person, because what sounds like one issue over the phone can turn out to be another. Then we lay out your options for Fairfax, agree on a plan and price, and get to work.

What does change locks cost in Fairfax?
We do not publish one-size-fits-all prices for change locks because every Fairfax job is a little different — a simple rekey is not the same as an all-keys-lost programming or a high-security install. What we do promise is transparency: call us, describe the situation, and we will explain what drives the cost and what to expect.
Honest pricing starts with an honest assessment. For change locks in Fairfax, the final cost depends on factors like the type of lock or vehicle, the hardware involved, how many locks or keys are needed, and the complexity of the job. Rather than quote a misleading flat number online, we confirm the details and give you a clear price before we begin.
Beware of prices that look too good to be true. A rock-bottom quote in Fairfax sometimes turns into a much larger bill on site. We prefer to be upfront: a fair, realistic price you agree to before we begin, with no bait and switch.
