Modern vehicles demand far more than a simple metal blank cut on a grinding wheel. Today's keys contain transponder chips, proximity sensors, and rolling-code fob technology that must be programmed to a specific vehicle's immobilizer system. Our technicians carry professional-grade key-cutting and OBD-II programming tools capable of handling a wide range of domestic and import makes — from Ford and GM trucks to Honda, Toyota, Hyundai, BMW, and beyond. Whether you need a basic key cut, a transponder key programmed, a smart proximity fob cloned, or a push-button start system rekeyed, we handle it on-site, at any hour.

Car Key Replacement by Make and Model: What Actually Goes Into the Job
Not every car key replacement is the same process, and the differences matter. A 2005 Honda Civic uses a basic transponder chip (ID46) that can often be cut and cloned in minutes with the right programmer. A 2020 Ram 1500 with a proximity smart key requires JTAG-level OBD programming and PIN extraction from the vehicle's ECU — a process that can take longer and requires the right software licenses for that platform. A 2018 BMW 5 Series with a display key involves encrypted Bluetooth pairing on top of standard transponder programming. Our technicians stay current with the specific protocols for each make and model, which is why we ask for your year, make, model, and VIN when you call — it lets us confirm the right equipment is loaded before we arrive.

Mobile Car Key Replacement in St. Augustine: We Come to You, Day or Night
Being stranded without a working key is genuinely stressful, and the solution should not require a tow truck, a dealership service appointment booked three days out, or a long wait on hold. When you call Augustine Locksmith Pro at (904) 585-2997, a real person answers — every hour, every day — and dispatches the nearest available technician to your exact location. We serve all of St. Augustine proper, St. Augustine Beach, Anastasia Island, Vilano Beach, Ponte Vedra Beach, World Golf Village, Nocatee, and surrounding St. Johns County communities. If you are in a parking garage on Riberia Street or on the shoulder of I-95 near exit 318, we come to you.
Our mobile units carry dedicated automotive key-cutting machines and programming interfaces rather than relying on a single universal tool. This means we can usually complete the job at your location without towing your vehicle anywhere. For situations where a key has broken off in the ignition — a more involved repair — we perform extraction and, where possible, re-cut and re-program a replacement on the spot so you leave driving, not waiting. Every job begins with ownership verification (government ID and registration or title), which protects you and ensures our service is used responsibly. Call (904) 585-2997 any time — we answer 24/7.
Understanding Pricing: Factors Behind Your Quoted Cost
We do not publish flat rates, because car key work is not one-size-fits-all. The final cost of a job depends on several real variables: the vehicle's make, model, and year (which determines key type, chip complexity, and programming time); whether you have a working key to duplicate from or require all-keys-lost programming, which is more labor-intensive; the time of day and day of week, since overnight and weekend dispatch carries different operational costs; travel distance from our nearest technician to your location; and the physical parts required — a basic transponder blank costs very differently from a proximity smart key for a late-model luxury vehicle. We confirm an exact up-front price before any work begins, so there are no surprises on the invoice. There is a call-out component to any mobile service visit, and that is factored into the quote you receive over the phone before we dispatch.
Beyond Car Keys: Full-Spectrum Locksmith Services in St. Augustine
Augustine Locksmith Pro is not only an automotive locksmith. Our trained technicians handle residential and commercial lock work throughout St. Augustine — including mortise lock installation, repair, and replacement for historic homes and downtown commercial properties where traditional mortise hardware is common. A mortise lock, which seats into a deep pocket routed into the door edge rather than surface-mounting, is the standard on many of the older wood-door storefronts along King Street and in the historic district. Proper mortise lock service requires understanding the full mechanism — cylinder, case, cam, and tailpiece — and our team handles it correctly, preserving the door and the surrounding frame.
If you need a locksmith for your business — whether that means rekeying an office suite after staff turnover, installing a commercial-grade mortise lock set on a high-traffic entrance, or setting up a master-key system for a property management operation in the World Golf Village area — our commercial locksmith capabilities cover it. For homeowners who need to rekey their home after a move or a lost key, we rekey cylinders on-site to your existing keys or cut a fresh set. And if you find yourself locked out — of your car, home, or business — our first step is always checking for safe alternatives (spare keys, unlocked secondary entrances) before any tool touches your hardware, keeping your locks intact wherever possible.
Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
What is a locksmith call-out fee, and does Augustine Locksmith Pro charge one?+
A call-out fee — sometimes called a service call or dispatch fee — is the base charge a mobile locksmith applies to travel to your location and assess the job, separate from the cost of labor and parts. Yes, like virtually all mobile locksmith services, we include a call-out component in our quoted price. However, we confirm the full, all-in price with you over the phone before dispatching, so the call-out cost is never a hidden add-on that appears at the end of the job.
How much does a locksmith cost in Florida for a car key replacement?+
Florida has no fixed statutory rate for locksmith services. The cost varies based on your vehicle's make and model, the key technology involved (basic transponder versus proximity smart key), whether you have a working key to copy from, the time of day, and how far the technician needs to travel. Because these factors combine differently for every call, we quote an exact price for your specific situation before any work begins — that way you know precisely what to expect with no guesswork.
What does 'pop a lock' mean, and is that what you do when someone is locked out of their car?+
'Pop a lock' is a colloquial phrase that refers to a locksmith opening a vehicle door when the owner is locked out, using professional tools designed for that purpose — not brute force or damage. At Augustine Locksmith Pro, when you are locked out of your car, our technician first confirms your ownership of the vehicle, then uses appropriate non-destructive methods to access the door where possible, protecting your weather stripping and lock mechanism. Our goal is always a damage-free opening. If you need a key made afterward because yours is lost, we can cut and program a replacement on the spot.
I need a key for my car and I have no spare — can you make one without the original?+
Yes. When all keys are lost, we use your vehicle's VIN and, depending on the make and model, either retrieve the key code from a database or use an OBD-II diagnostic interface to extract PIN and security data directly from the vehicle's computer. We then cut a new key blank to that code and program the transponder or proximity chip to the immobilizer. This process takes longer than duplicating from a working key and is reflected in the quoted price, but it is fully achievable on-site without towing your vehicle to a dealership.
I need a locksmith for my business — do you handle commercial locks like mortise locks?+
Absolutely. Commercial locksmith work is a core part of what we do. Mortise lock service — including cylinder replacement, case repair, and full lock-set installation — is something our technicians perform regularly on commercial doors throughout St. Augustine, including the older storefronts and professional buildings in and around the historic district. We also handle master-key system setup, rekeying after employee turnover, and access hardware upgrades for offices, retail spaces, and multi-unit properties. Call (904) 585-2997 to discuss your commercial needs — we are available 24/7.
I need to rekey my home — how is that different from replacing my locks entirely?+
Rekeying changes the internal pin configuration of your existing lock cylinder so that old keys no longer work and a new key is cut to match the new configuration. The hardware — the lock body, knob, or deadbolt — stays in place. It is the right solution when you want to ensure previous keyholders no longer have access (after a move, a lease change, or a lost key) but your existing hardware is in good condition. Replacing the entire lock makes more sense when the hardware is worn, you want to upgrade the security grade, or you are changing lock types — for example, switching from a door knob lock to a mortise lock or a high-security deadbolt. Our technicians can assess your doors and recommend the right path, with a confirmed price before we start.
