"Lost my keys somewhere on the beach at Fernandina. Called and the tech came right to the beach access parking lot, confirmed the key type for my vehicle, cut and programmed a new transponder key in about 40 minutes. Never had to move the car. Way less than I was expecting to pay."

We Come to Your Vehicle — Fully Equipped to Handle Most Keys on the Spot
A lost or destroyed car key used to mean an automatic tow to the dealership, a multi-day wait for a replacement, and a bill that often landed between $250 and $500 or more depending on the vehicle. That's still what happens if you call a dealer first.
Our mobile units carry precision key-cutting equipment and the electronic programming tools needed to create and program replacement keys for the vast majority of vehicles on North Florida's roads — sedans, trucks, SUVs, luxury makes, and most European imports. For many vehicles, we can have a fully functional replacement key in your hand inside of 45 minutes from the time you call, without your car moving an inch.
Before we dispatch, we'll ask for your vehicle's year, make, model, and whether you have any existing working keys. That information lets us confirm what key type your vehicle uses, what programming method is required, and give you a realistic price range before we arrive. No surprises.
The 5 Types of Car Keys — What You Have Determines What Replacement Costs
This is the most important thing to understand about car key replacement, and it's something most locksmith websites don't explain clearly. The type of key your vehicle uses directly determines how involved the replacement is, how long it takes, and what it costs.
1. Standard Mechanical Keys
These are flat metal keys with no electronics — found on vehicles generally made before the mid-1990s and a small number of basic modern vehicles. There's no chip to program, no pairing required. We pull the key code from your VIN or read your lock cylinder directly, cut the blank on our machine, and the job is done in minutes. These are the fastest and least expensive replacements we make.
2. Transponder Keys (Chip Keys)
The most common key type on the road today — used on most vehicles made from the mid-1990s onward. There's a small microchip embedded in the plastic key head that communicates with your vehicle's immobilizer control unit. When you insert the key and turn the ignition, a receiver coil in the ignition reads the chip's unique code. If the code doesn't match what the ECU expects, the engine won't start — even if the mechanical blade is cut correctly.
Replacement requires two steps: cutting the blade to the correct bitting code, and programming the chip to be recognized by your vehicle's immobilizer. We handle both on-site using OBD-II port programming or EEPROM reading depending on your vehicle's make, model, and year.
3. Remote Head Keys
A transponder key with the lock and unlock buttons integrated directly into the key head rather than on a separate key fob. These require both mechanical key cutting and remote frequency pairing. Common on domestic vehicles from the 2000s through the mid-2010s. We program these on-site for most makes and models.
4. Proximity Keys (Smart Keys / Push-to-Start)
The key stays in your pocket or bag — the vehicle detects its presence via low-frequency radio signal and enables the start button to function. No key insertion required. These are the most complex replacement keys we program, requiring specific hardware and software protocols that vary considerably by manufacturer.
Most domestic and Japanese makes are within our full on-site capability for proximity key programming. European luxury vehicles — particularly newer Audi, BMW, and Mercedes-Benz models using KESSY or similar proprietary keyless entry architectures — can be more involved, and we'll tell you exactly what's possible for your specific vehicle before dispatching.
5. Laser-Cut Keys (Sidewinder Keys)
Recognizable by their distinctive winding cut pattern on the blade's center track rather than the standard serrated edge. Used on many European vehicles and some domestic makes as a higher-security mechanical key design. These require specialized cutting equipment with a rotating cutter rather than a standard tracer cutter — we carry this equipment. Laser-cut keys are often combined with transponder chips, so replacement involves both precision cutting and chip programming.
Dealership vs. Locksmith — The Honest Comparison
The most common question we get on car key replacement calls is some version of: "Should I just call the dealership?" Here's the honest breakdown.
Cost: A dealership replacement for a transponder key typically runs $200–$400 depending on the make. Push-to-start proximity keys from a dealer often run $300–$500 or more. Our pricing for the same key types runs significantly lower — we'll quote you the exact number before we dispatch. The gap exists because dealers source OEM keys at OEM prices and apply dealer labor rates; we source quality aftermarket or equivalent blanks and operate as a mobile service with lower overhead.
Time: Most dealers require you to tow the vehicle to their service department (adding towing cost if your car won't start), schedule a service appointment which may be days out, and wait for the service department to complete the job. We come to your vehicle, typically within 30 to 45 minutes of your call, and complete most replacements on-site in the same visit.
Limitations: Some situations genuinely require dealer involvement. Certain late-model European vehicles with advanced all-keys-lost security protocols — particularly some newer BMWs, Mercedes, and a handful of other makes — may require dealer-side security system authorization as part of the key programming process. We'll tell you honestly if your vehicle is one of them when you call with the details. We'd rather set accurate expectations upfront than show up and tell you on-site that we can't finish the job.
All-Keys-Lost Programming — When You Have No Working Keys at All
Replacing a key when you still have one working key is relatively straightforward for most vehicles. All-keys-lost situations — where every key has been lost or destroyed and the vehicle's immobilizer system has no recognized keys — require a different approach that's more technically involved.
For most domestic vehicles, all-keys-lost programming is done through OBD-II port access using manufacturer-specific security bypass protocols. We carry the software and hardware adapters needed for the majority of Ford, GM, Chrysler, Toyota, Honda, Hyundai, Kia, and Nissan all-keys-lost scenarios.
For vehicles with more restrictive security architectures — some late-model European makes, certain luxury vehicles where the BCM and ECU must be synchronized — the process may require EEPROM reading of the immobilizer control module, which is a more involved procedure but still frequently achievable on-site with the right equipment.
What we need from you for any all-keys-lost job: your vehicle's VIN, government-issued photo ID in your name, and vehicle registration or insurance documents confirming you own or have authorized use of the vehicle. We take ownership verification seriously on all-keys-lost calls — this is exactly the type of service a vehicle thief would want to abuse, and we won't perform it without clear proof of ownership.
Key Fob Replacement & Programming
A key fob that's stopped working often isn't a dead battery — particularly in North Florida's coastal communities where humidity and salt air accelerate internal circuit board corrosion in ways that look exactly like a dead battery from the outside.
Diagnosing the Real Problem First
Before replacing a fob, we check three things: battery condition, synchronization status, and internal circuit board integrity. A fob that's lost synchronization with the vehicle's receiver can often be re-paired through a programming sequence without replacing the fob at all — a five-minute fix if that's the issue. A fob with a corroded circuit board looks the same from the outside as a low-battery fob but won't respond to a battery change.
Fob Replacement and Programming
When replacement is necessary, we carry aftermarket and OEM-equivalent fob blanks for most common vehicles. We program them on-site to your vehicle's existing key recognition system. For vehicles where the fob and transponder are integrated in a single unit — which includes most remote head keys and all smart keys — the replacement and programming process is the same as a full key replacement.
Remote Programming Only
If you have a new fob (purchased separately or from a dealer) and simply need it programmed to your vehicle, we can often handle remote programming alone without cutting a new key blade. Call with your vehicle year, make, and model and we'll confirm whether we can program a standalone fob for your specific vehicle.
Key Replacement for Specific Vehicle Situations in North Florida
Beach and Waterfront Locations
Keys lost at the beach — in the sand at Jacksonville Beach, Fernandina Beach, or St. Augustine Beach, left in beach gear at Ponte Vedra, or dropped near the water anywhere along the coast — are a regular part of our call volume. We come to beach parking lots, beach access points, and marina parking areas. If you're at a location where parking enforcement is active, note your vehicle's location when you call us so we can account for any time pressure on your end.
Rental Vehicles
We can replace keys for most rental vehicles, but rental company policy varies on how they prefer to handle key replacement. Call the rental company first to understand their process — some prefer you go through them directly, others are fine with independent locksmith service. We can work with rental agencies directly if that's what the situation calls for.
High-Value and Luxury Vehicles
We regularly program keys for Audi, BMW, Mercedes-Benz, Lexus, Acura, Infiniti, Land Rover, Porsche, and Volvo vehicles. These makes use more complex transponder protocols than most domestic vehicles, which is why some locksmiths decline them or quote them without the equipment to back it up. We carry the specialized programming platforms — including Autel, Xhorse, and IANA-compatible systems — needed for most luxury and European key programming applications.
Older and Classic Vehicles
Pre-1995 vehicles without transponder systems are straightforward key replacements — we cut from a key code or the lock cylinder directly. Some classic vehicles have unusual keyways or older proprietary blanks that may require sourcing specific blanks; if your vehicle is a less common make or a classic with non-standard hardware, call us first with the details and we'll confirm availability.
Commercial Vehicles and Fleet Keys
We service commercial vehicles including light trucks, cargo vans, and most fleet vehicles. For businesses managing a fleet in the Jacksonville metro or elsewhere in North Florida, we can work with fleet managers on scheduled service or emergency key replacement.

What Customers Say About Our Car Key Replacement Service
"Had my only key to my Audi Q5 go missing near Ponte Vedra. These guys actually had the right equipment for an Audi — a lot of shops I called said they couldn't do it. Came out, programmed a new smart key on-site, worked perfectly. Saved me a very expensive tow and dealer visit."
Marcus T., Ponte Vedra Beach
"Keys locked in the car at the St. Johns Town Center on a Saturday afternoon. They came in about 25 minutes, got me in without any damage to the door, and since I'd actually lost the spare months ago and never replaced it, they cut me a new key on the spot too. Handled the whole situation in one stop."

Frequently Asked Questions — Car Key Replacement
How quickly can you reach me in North Florida?
For most of Jacksonville and Duval County: 15 to 30 minutes. Orange Park and Ponte Vedra Beach: similar range. St. Augustine, Fernandina Beach, Yulee: 30 to 45 minutes. We'll give you a specific estimate when you call based on where our nearest unit is positioned.
Can you replace my key if I've lost all copies?
Yes, for most vehicles. All-keys-lost programming is a more involved process than replacement when you have a working key, but it's within our capability for the vast majority of domestic and Japanese vehicles. Some European luxury makes with highly restrictive security protocols may require partial dealer involvement — we'll tell you honestly on the call if that applies to your vehicle.
Do you need the car to be at a specific location?
No. We come to wherever your vehicle is — a parking lot, a street, your driveway, a beach access area. The only thing we need is the vehicle accessible and your proof of ownership available when we arrive.
How do I know what type of key my car uses?
The easiest indicator: if your key has a thick plastic head (rather than just a metal blade), it has a transponder chip. If your vehicle has a push-button start, it uses a proximity key. If you're not sure, give us your year, make, and model when you call and we'll identify the key type before dispatching.
Is it really cheaper than the dealership?
For most vehicles, yes — meaningfully so. The gap is largest on transponder and proximity keys. We're happy to quote you a specific number over the phone so you can compare directly before committing.
Can you program a key I bought online?
Sometimes. Aftermarket key blanks from reputable suppliers that match your vehicle's exact frequency, chip type, and protocol specifications can often be programmed using the same methods as OEM blanks. Low-quality or incompatible blanks — particularly those that don't precisely match your vehicle's requirements — may not program correctly regardless of the technician's skill. If you've already purchased a key blank and want to know if it's likely to work, call us with your vehicle details and the blank's part number and we'll give you an honest assessment.
