Modern vehicles use everything from transponder chip keys to push-to-start proximity smart fobs, and each requires the right blank plus programming to your car's system. We handle them all across Larkspur.

Dealerships are not your only option for a replacement key. An experienced mobile automotive locksmith often provides the same result — a properly cut and programmed key — with more convenience and, frequently, a friendlier price.

Being a mobile locksmith in Larkspur 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.

Car key and fob services we provide

Whatever your vehicle needs, our mobile automotive service can usually handle it in Larkspur:

Everything happens at your location. There is no waiting room and no tow — just a mobile technician, the right tools, and a working key handed to you when we are done.

  • Replacement keys and fobs cut and programmed on location
  • Lost-key and all-keys-lost programming (with proof of ownership)
  • Spare keys and fobs so you always have a backup
  • Transponder, remote head, and proximity smart key programming
  • Key fob battery and shell replacement
  • Broken key extraction and ignition help

How mobile car key replacement works

We start by confirming the exact vehicle and key technology, because the right approach for one model year can be wrong for another. From there we cut the key, program it to the vehicle's system, and verify start, lock, unlock, and remote functions.

Where the vehicle supports it, we can also remove previously lost keys from the system during an all-keys-lost job, so an old key that fell into the wrong hands can no longer start your car. Security, not just convenience, is the goal.

Dealerships are not your only option for a replacement key. An experienced mobile automotive locksmith often provides the same result — a properly cut and programmed key — with more convenience and, frequently, a friendlier price.

Understanding your car key type

The right approach depends on the key. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware — which is why we confirm your exact make, model, and year before quoting.

A fob that suddenly stops working is not always dead. Sometimes it just needs a fresh battery or a new shell; other times it needs reprogramming. We can test which it is before assuming you need a full replacement.

The smartest move: a spare key

A fob that suddenly stops working is not always dead. Sometimes it just needs a fresh battery or a new shell; other times it needs reprogramming. We can test which it is before assuming you need a full replacement.

The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.

What car key replacement costs

That is why we quote based on your specific make, model, and year rather than a generic number. Call (408) 755-3415 with those details and whether you still have a working key, and we will give you a clear, honest price.

An all-keys-lost situation typically costs more than cutting a spare, simply because it requires additional programming. It is one more reason a spare key made today is such a smart, money-saving move.

Car key pricing varies more than people expect, because the key itself does. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware, and programming complexity differs by vehicle too.

Why choose 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 Larkspur customers money — and that judgment is what we bring to every visit.

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.

  • Mobile-first service — we come to you across Larkspur and Marin County, so there is no towing your car or hauling hardware to a store.
  • Respect for your time — we aim to arrive when we say and finish efficiently without cutting corners.
  • Clear communication — you hear the plan and the pricing before any work begins, so there are no surprises.
  • Care for your property — we favor non-destructive methods and protect doors, vehicles, and finishes while we work.
