Lost your car keys? Broken key stuck in the ignition? We provide complete car key replacement for virtually every make and model on the road. Our process begins with verifying your vehicle ownership, then our skilled technicians use precision key-cutting machines to craft a perfect replacement. For modern vehicles with transponder chips and proximity keys, we use OEM-grade programming equipment to ensure your new key communicates seamlessly with your car's immobilizer system no aftermarket shortcuts, no compromises on security or function.
Modern vehicles use sophisticated transponder chips embedded in the key head that communicate with the car's ECU. Without proper programming, even a perfectly cut key won't start your car. Our technicians use professional-grade diagnostic and programming tools the same technology used by dealerships to correctly program transponder keys for your specific vehicle. This includes EEPROM-level programming for the most advanced security systems, ensuring your replacement key works with zero issues from day one. We handle BMW EWS, Toyota G-chip, Ford PATS, GM VATS, and virtually every other system.
Push-button start vehicles rely on proximity smart keys that use rolling code technology to prevent theft. Replacing these is a complex process requiring specialized equipment and expertise. We supply and program genuine-quality smart keys and key fobs for virtually all brands including luxury makes like Mercedes-Benz, Audi, Land Rover, and Lexus, as well as mainstream brands including Honda, Toyota, Chevrolet, and Ford. Our prices for smart key replacement are often significantly lower than dealership rates, with the same quality of programming and the added convenience of coming directly to you.
A worn or damaged ignition cylinder can make starting your vehicle impossible or even dangerous if a broken key fragment is lodged inside. Our technicians are skilled at extracting broken keys from ignition cylinders without damaging surrounding components. We can rebuild worn ignition cylinders, replace the entire ignition assembly, and re-key the new cylinder to work with your existing keys where possible. Every ignition repair includes a full test to confirm proper function across all key positions Start, On, Accessory, and Off before we leave y.
Locked your keys inside your car? Whether it happened at a grocery store, a trailhead, or in your own driveway we respond fast. Our technicians use professional, non-destructive entry tools to unlock your vehicle quickly and safely, without any damage to your door, window seals, or locking mechanisms. We're equipped to handle traditional lock cylinders, electronic door locks, and even some of the more challenging security systems in modern luxury vehicles. We work on sedans, trucks, vans, SUVs, and commercial vehicles of all sizes.
Having a spare key isn't just convenient it's smart planning that could save you hundreds of dollars in emergency lockout costs down the road. We offer precision key duplication for all types of car keys, including standard metal keys, laser-cut (sidewinder) keys, and transponder keys that require programming alongside cutting. Bring your existing key to or have us come to you, and we'll create an identical, fully functional spare in minutes. We recommend all vehicle owners have at least two working keys and we make it affordable and easy to get there.
From Santa Rosa and beyond, our mobile technicians cover Sonoma County and neighboring areas bringing professional car key services directly to wherever you need us. Over 30 cities and communities served.
Using computer-guided precision machinery, we produce perfectly cut keys for every profile standard double-sided, single-sided, laser-cut (sidewinder), and dimple keys. Our cutting is accurate to within 0.01mm tolerance, ensuring smooth operation in your lock cylinder with no binding or wear. We maintain an extensive inventory of key blanks covering thousands of vehicle applications from 1970 to present day.
Today's key fobs do far more than unlock doors they control alarms, remote start systems, trunk releases, and in some cases even adjust driver settings. Programming a new fob requires accessing your vehicle's BCM (Body Control Module) and syncing the new device's unique ID code to your car's security database. We use professional OBD-II and PIN-code programming methods to ensure reliable, permanent programming that holds even through battery changes and system resets.
For standard key cutting (non-transponder keys), the process typically takes 10 to 20 minutes from arrival. For transponder keys requiring electronic programming, allow 20 to 45 minutes depending on the vehicle's security system complexity. Smart keys and proximity fobs can take 30 to 60 minutes for vehicles with multi-step authentication. We'll always give you an accurate time estimate before we begin, so you can plan your day accordingly.
Our technicians arrive fully prepared with the right equipment, blanks, and software for your specific make and model. We don't make unnecessary trips back to a shop everything is handled from our mobile unit at y.
Yes we program keys for virtually every make and model sold in the United States, including luxury and exotic brands. Our programming equipment covers Mercedes-Benz, BMW, Audi, Lexus, Land Rover, Jaguar, Porsche, Volvo, Acura, Infiniti, and Cadillac, as well as all major mainstream brands including Toyota, Honda, Ford, Chevrolet, Dodge, Nissan, Hyundai, and Kia.
For ultra-rare or specialty vehicles, we may need to source a specific blank or software module call us with your VIN and we can confirm availability before scheduling your appointment. In the vast majority of cases, we arrive fully equipped for your vehicle.
We take vehicle security seriously verifying that you are the rightful owner before cutting any key protects you and every vehicle owner we serve. Standard documentation includes a government-issued photo ID, your vehicle registration, and proof of qualification (at least one of the latter two must match the name on your ID).
If the vehicle is registered in someone else's name (a family member, employer, or leasing company), we may require additional authorization documentation. When in doubt, call us before your appointment and we'll walk you through exactly what you need to bring. The process is straightforward for legitimate owners.
Absolutely this is one of the most common situations we handle. Even without an existing key, we can create a new one using your vehicle's VIN number and our access to vehicle key code databases. For older vehicles (pre-1990), we typically decode the lock cylinder itself to determine the cut pattern. For modern vehicles with transponder systems, we use advanced diagnostic methods to access the vehicle's immobilizer system and generate fresh credentials for a new key.
The process takes slightly longer without an original key to reference, but it is entirely achievable in a single on-site visit for most vehicles. Bring your VIN (found on your registration or inside the driver-side door frame), your ownership documents, and your ID and we'll take care of the rest.
On average, our prices are 40 to 60 percent lower than dealership rates for the same service. A smart key replacement at a dealership might cost $350-$600 once you factor in towing, programming fees, and the key itself. We typically perform the same job for $150-$280, depending on the vehicle and we come to you, saving towing costs entirely.
Our overhead is lower as a specialized mobile service, and we pass those savings directly to you. We don't upcharge because your car is a luxury brand or because it's an emergency. Our pricing is based on the actual complexity of the work not on what we think we can get away with charging.
Yes we operate 24 hours a day, 7 days a week, 365 days a year, including all major holidays. Emergencies happen at the most inconvenient times, and being locked out or stranded without a key is genuinely disruptive regardless of when it occurs. Our after-hours and weekend services are available at the same transparent rates with no excessive emergency premiums.
Simply call (707) 598-8101 at any hour. You will speak to a real person not an answering machine and we will dispatch a technician to y as quickly as possible. Our goal is to have someone with you within 30 minutes across our primary service area in Sonoma County.
We stand behind every job we perform with a 90-day workmanship guarantee. Before our technician leaves y, the new key is tested thoroughly across all functions starting the vehicle, operating the door locks, trunk release, and any remote features. We don't leave until you've confirmed everything works as expected.
In the rare event an issue arises afterward that is related to our work, contact us and we will return promptly to resolve it at no additional cost. Our reputation is built on getting the job right and making it right on the rare occasion something goes wrong.
Yes broken key extraction is a specialty service we perform regularly. A key that snaps inside an ignition cylinder or door lock is a frustrating situation, but it doesn't necessarily mean you need a new ignition or lock. Our technicians use professional hook picks, extraction kits, and sometimes specialized scopes to remove broken key fragments without damaging the surrounding cylinder or tumblers.
Success depends on how deeply the fragment is lodged and whether the break point is accessible. In most cases, we can extract the fragment non-destructively. If the cylinder is already damaged, we'll give you an honest assessment and a quote for repair or replacement on the spot. We always aim for the least invasive, most cost-effective solution for your situation.
