Car key replacement in Fairfax typically runs $180 – $340 for standard transponder keys with programming, and most jobs are completed same-day at your location. If you’ve lost your only key, snapped a blade in the ignition, or need a spare before handing one over to a house sitter, you need a locksmith who actually works on automotive key systems, not just door hardware. Cypress Lock & Key has been serving Fairfax, CA for years with the programming equipment and key blanks that most local hardware counters simply don’t carry. Call (877) 265-4385 and we’ll quote the full price on the phone before anyone is dispatched.
Why Cypress Lock & Key Is Fairfax’s Preferred Car Key Replacement Company
Fairfax isn’t a big-box town. The roads wind, the lots are shaded, and people here tend to keep their cars for years. When a key snaps or a fob stops holding a charge, the nearest dealership is a drive over White Hill or down into San Rafael, and the dealership service bay doesn’t care that you’re late for a shift in downtown Fairfax or a parent pickup at Manor School. Our Car Key Replacement technicians arrive to homes along Bolinas Road, Cascade Drive, and the side streets off Sir Francis Drake with the same programming gear a dealership uses. The difference is we come to you.
Noel Carver leads our team, and his focus has always been about doing the job properly on the first visit. That matters in Fairfax because many homes here have narrow driveways and no street parking to spare for a second trip. We quote a flat price per job before dispatch. That price is the price on the invoice. No call-out surcharge added when the van pulls up. That’s the standard we hold for every Fairfax customer, whether you drive a Toyota parked on a steep Bolinas Road shoulder or a Subaru with a key that’s decided it’s had enough of the wet season.

Our Car Key Replacement Services in Fairfax
Lost Car Key Replacement
When there’s no key at all, we cut and program a new one on-site using the vehicle’s onboard programming sequence or our handheld programmer, depending on the year and model. Losing a car key in Fairfax is common in the wet months when people are juggling rain jackets, farmers market bags, and muddy boots on the way in from a soaked Cascade Drive driveway. Most standard lost-key replacements run $180 – $300 in Fairfax depending on whether the key is a basic transponder, a remote-head key, or a push-to-start fob. The quote you hear on the phone is what you’ll pay.
Key Fob Replacement and Programming
The fob is the part that remote-lock and unlock buttons live on, and Fairfax’s damp, shaded lots are not kind to the internal circuit boards. Moisture gets into the casing after a few seasons of rain and heavy marine air, and the buttons stop making reliable contact even though the key still turns the ignition. We replace and program fobs for most makes and models, and the pricing in Fairfax ranges from $120 – $220 for aftermarket fobs and up to $350 for factory originals on newer vehicles. Call (877) 265-4385 and we’ll tell you exactly what your vehicle needs.
Ignition Key Extraction and Repair
A key that snaps off in the ignition leaves you stranded, and Fairfax’s hillside parking makes a tow truck a genuinely bad option on a narrow lane with no shoulder. We extract broken key blades from ignitions and door locks on-site, inspect the cylinder for wear, and cut a replacement blade from the extraction profile where possible. The cost for extraction plus replacement key in Fairfax runs $150 – $250, and because we bring the extraction kit and the key-cutting equipment to you, there’s no tow bill added to the total.
Spare Key Duplication
One working key is not enough, especially in a household where two adults commute out of Fairfax in different directions. A spare transponder key duplication runs $80 – $150 in Fairfax, and we program it on the spot so it starts the vehicle, not just opens the door. If you rent a cabin off Bolinas Road with a housemate or Airbnb guest rotation, a spare key is cheaper than a lockout call at 11 p.m. on a wet February night. We’ll cut and test the spare before we leave the driveway.

Trusted Brands We Service in Fairfax
Most car key replacement work we do in Fairfax involves factory transponder systems from Toyota, Honda, Subaru, Ford, Chevrolet, and Nissan, plus Volkswagen and Audi for German makes common in the Bay Area market. Beyond automotive, Cypress Lock & Key works across eight lock brands including Baldwin, Sargent, Mul-T-Lock, and Abloy. That’s directly relevant in Fairfax because many of the original door locks on 1920s – 1950s cabins are Baldwin mortise sets with Sargent cylinders, and those brands are not something a parts-store kiosk stocks. We stock common key blanks and cylinders locally and can rekey vintage hardware in place without waiting for a dealer-order part.
Common Car Key Replacement Problems We See in Fairfax Homes
- Salt-air corrosion on transponder key contact points. Marine air works its way into key housings over time, pitting the metal contacts that connect the chip to the ignition cylinder. The key won’t turn or the engine computer won’t recognize it, and the failure looks like a dead chip, but it is often just a pitted contact that needs cleaning and recoding. We see this pattern on cars parked outside on shaded north-facing lots off Bolinas Road more than anywhere east of the ridge.
- Worn ignition cylinders that eat key blades. An ignition cylinder that takes more and more jiggle to accept the key is a worn cylinder, and it will eventually bind hard enough to snap the blade. Fairfax cars that sit in damp driveways for days at a time with moisture cycling through the lock are more likely to develop this. We repair or replace the cylinder and cut a matched key, usually saving the original door lock so one key still operates everything.
- Swollen wood-frame doors that interfere with the door lock, not the car key. When the door itself won’t latch, the car key isn’t the issue, but the family still can’t leave. On the hillside lanes off Bolinas Road, the classic call is a swollen wooden door that won’t throw the mortise lock after the rainy season. The jamb and strike have shifted with soil moisture, so we realign the hardware in place rather than replacing the lock, then refit a marine-grade strike plate to stop the damp from eating hardware next winter.
- Lost transponder keys on rental cabins and shared driveways. Fairfax has a steady flow of rental turnover on the smaller cabins around Cascade Drive and up toward Sky Oaks, and every new tenant means keys that have wandered off, been tossed in a drawer, or gone home with a former housemate. We cut replacement transponder keys and rekey the entry doors so the previous tenant’s keys don’t work anymore, which is a more cost-effective security upgrade than replacing hardware outright.

FAQs – Car Key Replacement in Fairfax
In most Fairfax cases, no. The lock cylinder and mortise body are usually sound; what has failed is the alignment between the strike plate and the swollen jamb. Damp winters and shaded redwood lots cause the wood frame to swell and shift, which throws the strike out of line and stops the latch from seating. Fixing it starts with door realignment or a repositioned marine-grade strike, not a new lock. We see this most often on homes along Bolinas Road and Cascade Drive. If the cylinder is also pitted from salt air, we clean or rebuild it in place. Call (877) 265-4385 and we’ll tell you what’s actually wrong and what it costs before we dispatch.
Fairfax’s damp, marine-influenced winters corrode lock cylinders and strike plates faster than the bay-side towns east of the ridge, particularly on shaded north-facing entries. The key sticks because corrosion has built up on the cylinder wafers or pins, and the key is fighting the internal mechanism, not because the key is worn. Annual cylinder freeing is a recurring call in Fairfax, and the fix is removing the cylinder, cleaning the internals, lubricating with a marine-rated lubricant, and in some cases replacing pitted pins. It is a $75 – $150 service call in Fairfax, and it prevents a snapped key later. Use graphite or silicone sparingly, and call us rather than forcing the key.
Yes, and we recommend it in most Fairfax cabins, bungalows, and hillside homes. Many of the 1920s – 1950s wood-frame houses here have original mortise locks and Baldwin entry sets, and swapping in a modern deadbolt leaves non-standard door thicknesses misaligned and throws away the period set. We rebuild and rekey pin and tumbler cylinders in place with fresh keys so the old tenant keys stop working, and we fit marine-grade strikes where the damp north-facing entries eat hardware. Rekeying an original mortise lock in Fairfax typically runs $95 – $165 per cylinder, less than a replacement lock plus labor. Call (877) 265-4385 for a phone quote.
Often not cleanly. Fairfax’s older cabins and bungalows frequently have doors thinner or thicker than the 1¾-inch standard that modern deadbolts are built for, and forcing a standard bolt leaves the throw only partially engaged. In those cases we either rebuild the existing mortise lock in place or fit an extension tailpiece and custom strike to match the non-standard thickness. That preserves the original Baldwin hardware and leaves a functional, properly aligned latch. Big-box locksmiths won’t stock the parts. We do. Call (877) 265-4385 and describe your door; we’ll tell you honestly what fits and what doesn’t.
Cypress Lock & Key handles both. Car key replacement in Fairfax is one of our three core services, alongside emergency locksmith response and lock rekeying. Same-day service is standard for most vehicle key jobs, from transponder replacement to fob programming to snapped-key extraction. This means you don’t have to call a dealership and then call us for the door lock; one phone call covers the car key in the ignition and the mortise lock on the front door. Call (877) 265-4385 for a free estimate on car key replacement or any door hardware work.
