Car key replacement in Kentfield typically runs $180 – $340 for a standard transponder key, and $250 – $550 when programming is required for newer vehicles with proximity fobs or push-button start. Most jobs in the 94914 area are completed same-day, often within 60 – 90 minutes of arrival. If you’ve lost your only key, snapped a blade in the ignition, or need a spare cut and programmed, call (877) 265-4385 and we’ll give you an exact quote before anyone is dispatched.
Kentfield isn’t a typical suburb. The homes here sit back from the road behind gates and mature oaks, and many driveways are long enough that a locksmith who doesn’t know the area wastes twenty minutes just finding the right entrance. We’ve worked Kentfield long enough to know College Avenue from Woodland Road, and we’ve cut and programmed keys for everything from a 2008 Honda Accord to a brand-new Range Rover parked off Laurel Grove Avenue.
Why Cypress Lock & Key Is Kentfield’s Car Key Replacement Company
Most locksmith shops in Marin are set up for house locks. They’ll cut a basic metal key, but when you hand them a transponder key or a proximity fob, they send you to the dealership. We’re not that shop. Noel Carver built Cypress Lock & Key to handle automotive key work alongside traditional locksmithing, because a locked-out homeowner and a stranded driver are often the same person on the same day.
Kentfield customers call us for two reasons: we show up, and we bring the right equipment. A mobile programmer, a full key blank inventory, and the diagnostic tools to pair a new key to the vehicle’s immobilizer. We’ve worked on Sargent mortise cylinders in a 1930s door and Schlage deadbolts on a 1970s remodel in the same afternoon. The hardware varies; the standard of work doesn’t.
Our response to Kentfield is genuinely local. We’re based in Oakland, but we dispatch techs who know Marin County roads well enough to reach Ross, Kentfield, and Larkspur without getting lost in the hills. When you call (877) 265-4385, you get a real person, a clear arrival window, and a technician who knows what a 1940s gate latch looks like.

Our Car Key Replacement Services in Kentfield
Transponder Key Cutting and Programming
Most vehicles built after 1998 have a transponder chip embedded in the key head. That chip talks to the vehicle’s immobilizer. No chip, no start. We cut and program transponder keys for Kentfield drivers on-site, usually in under an hour. We carry blanks for the common makes and models we see in the 94914 area, and we can order specialty blanks when a customer drives something less common.

Proximity Fob and Push-Button Start Keys
Newer cars don’t use a keyed ignition at all. The fob in your pocket handles it. When that fob dies or gets lost, you need a locksmith with the diagnostic equipment to program a new one to the vehicle, not a kiosk that copies a metal blade. We handle proximity fob replacement for Kentfield residents, including cases where the fob is the only key that ever existed for the car.

Rekey and Key Control for Gated Estates
Kentfield’s long gated driveways mean the gate lock is often the first and only line of defense before the front door. When a key is lost or stolen, we don’t just cut a replacement. We rekey the cylinders so the missing key no longer works. That’s the difference between a key replacement and actual key control. For estate properties, we also document how many keys are in circulation and recommend restricted keyways when the homeowner wants to prevent unauthorized duplication.

Emergency Car Key Service
A snapped key in the ignition or a lost key at 11 p.m. in Kentfield doesn’t wait for business hours. Our emergency dispatch covers the 94914 area with the same equipment we use during the day, including extraction tools for broken blade fragments and mobile programming for replacement keys. Call (877) 265-4385 and you’ll reach someone who can actually help, not a voicemail for an answering service.

Trusted Brands We Service in Kentfield
We work on the lock you already have, not the one we’d prefer to sell you. That includes the vehicle key systems from every major automaker, plus the residential and gate hardware that surrounds most Kentfield driveways: Schlage deadbolts, Kwikset cylinders, and the occasional Sargent mortise lock on an older estate door. Our techs carry keys, pins, and cylinders for all of them, because a car key replacement in Kentfield often starts at a gate or a front door before it ever reaches the vehicle.
Common Car Key Replacement Problems We See in Kentfield Homes
- Kiosk-copied keys that don’t work. Kentfield has a lot of high-end vehicles with transponder chips and restricted keyways. A kiosk can copy the metal blade, but it can’t program the chip. We regularly see customers who spent $30 at a hardware store only to discover the copy won’t start the car.
- Gate and door locks binding in wet winters. Kentfield’s Mediterranean climate means wet winters swell the wooden gates and solid-wood doors common to the area’s 1920s – 1970s homes. A swollen gate puts pressure on the lock cylinder, and a key that binds is a key that eventually breaks. We make seasonal adjustments to keep strike plates aligned.
- Stolen key rings with both car key and gate remote. This is a Kentfield-specific problem because so many properties have gated entries. Losing a car key is bad. Losing a car key plus the gate remote means someone now has access to both your driveway and your vehicle. Rekeying the gate and programming a new car key on the same visit is the fix.
- New car keys not integrated with alarm systems. Many Kentfield homes have layered security: gate, front door, alarm, cameras. A new car key or remote that isn’t added to the existing system leaves a gap. We coordinate with the homeowner’s alarm setup so a new key doesn’t trigger alarms or fail to register with the smart-home hub.
Pricing for Car Key Replacement in Kentfield, CA
A standard transponder key replacement in Kentfield runs $180 – $340, including cutting and programming. Proximity fobs and push-button start keys run $250 – $550 depending on the vehicle’s make, model, and year. Rekeying a gate lock or front door cylinder typically runs $75 – $125 per lock cylinder. If you need both a new car key and a rekeyed gate, we quote the combined job before we dispatch, and that’s the number on the invoice. There’s no surprise trip charge added when the tech arrives. Call (877) 265-4385 and we’ll quote your exact vehicle and lock setup over the phone.
What affects the price: the keyway type (standard vs. patented/restricted), whether the vehicle requires dealer-level programming, and how many locks need rekeying alongside the key work. A 1998 Honda is a different job than a 2022 BMW with a proximity fob and a proprietary keyway.

FAQs – Car Key Replacement in Kentfield
Yes. We’ll coordinate access with you when we arrive. If the gate itself is part of the problem, like a stolen remote or a lock that needs rekeying, we handle that on the same visit. Most Kentfield jobs are completed within 60 – 90 minutes of arrival at the property. Call (877) 265-4385 and let us know what kind of gate and vehicle you have, and we’ll confirm the timeline.
Call us first, and don’t wait. A stolen key ring with both a car key and a gate remote means someone could access both your property and your vehicle. We rekey the gate cylinder so the stolen key no longer opens it, and we program a new vehicle key on-site. We also walk you through whether a restricted keyway makes sense for your property going forward. The longer that key ring is out there, the wider the security gap.
Usually not directly, but they’re both symptoms of Kentfield’s wet winters. Wooden gates and solid-wood doors swell with moisture, which misaligns strike plates and makes keys bind in the lock. If your car key is also binding in the ignition, that’s typically a separate issue with the ignition cylinder or the key blade itself. We fix both. The gate needs a seasonal adjustment, and the ignition likely needs a new key or a cylinder inspection.
Yes. Patented and restricted keyways exist specifically so that a kiosk can’t copy them. We hold the proper key blanks and programming equipment for these vehicles, and we cut and program them on-site. If you’ve already tried a kiosk and the copy doesn’t work, we’ll replace it with a key that actually starts the car. No appointment needed for most vehicles.
Yes. When we program a new key or remote, we check whether the existing alarm or smart-home system needs to be updated to recognize the new fob. This matters more in Kentfield than most places, because many properties here run layered access control: gate, front door, alarm panel, and cameras. A new key that isn’t registered with the system can trigger false alarms or leave a door that the system thinks is still locked. We handle the coordination so you don’t have to call three different vendors.
