How our Key Fob Replacement works in Larkspur
Here is how a typical key fob replacement visit works when you call Avant Guard Locksmith in Larkspur:
Match the fob: We identify the correct fob for your vehicle.
Program: We pair the fob to your car's system.
Cut the blade: We cut any emergency blade the fob uses.
Test functions: We confirm lock, unlock, trunk, and start.
Throughout the visit we keep you in the loop. Before we touch anything on your Larkspur 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 Larkspur 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
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 Larkspur customers notice.
Choosing a locksmith comes down to trust, and trust is earned by being clear and doing careful work. In Larkspur, 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.
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 Larkspur customers money — and that judgment is what we bring to every visit.
- Local coverage — we serve Larkspur and nearby communities like Corte Madera, San Rafael, and Ross, so help is rarely far away.
- Clear communication — you hear the plan and the pricing before any work begins, so there are no surprises.
- 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.
- One team for everything — the same trusted number for your home, your business, and your vehicle in Larkspur.

Common benefits customers in Larkspur mention include new fobs cut and programmed on site, remote, proximity, and smart key options, often costs less than the dealership, and battery and shell service too.
During key fob replacement, 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 Larkspur, agree on a plan and price, and get to work.
