Ford F-250, F-350 & F-450 Super Duty All Keys Lost in Fort Worth (2026)
Quick answer: Lost your only Ford key in Fort Worth? Your fastest option is a mobile automotive locksmith who cuts and programs a new key at the truck, usually within a couple of hours of your call. Expect $150–$850 all-in for a Super Duty depending on the key type: a PATS transponder blade on an older F-250 sits low in that band, a remote-head key lands mid-range, and a push-button proximity fob with no surviving key reaches the top. Bring your VIN, photo ID, and proof of ownership. Call (817) 674-3595 for a firm number before anyone drives out.
Losing every key to a Super Duty is a different problem from losing the keys to a commuter car. The truck is usually loaded. It may be hitched. It may be parked where it blocks somebody else's work. A tow is not just expensive — for a three-quarter-ton or one-ton truck with a bed full of tools, it is a logistical mess.
As of July 2026, all-keys-lost calls on Ford Super Duty trucks are among the most common ford car key replacement jobs we run in Tarrant County, and almost all of them finish where the truck is parked. This guide walks through what Ford actually put in the ignition across the Super Duty generations, what each key type costs here, exactly what you need to prove the truck is yours, and where the honest limits sit.
What is actually in your Super Duty key
Ford has used three broadly different key architectures on the Super Duty line, and which one you have matters far more to the price than whether the badge says F-250 or F-450. The trim and the model year drive the cost, not the payload rating.
Early PATS era: cut blade with a chip in the head
From the late 1990s onward, Super Duty trucks shipped with a transponder key — an ordinary cut metal blade with a small chip molded into the plastic head. Turn the key and the ignition ring energizes that chip, the chip answers with a coded response, and Ford's Passive Anti-Theft System (PATS) decides whether the powertrain is allowed to fuel. No valid answer means the engine cranks strongly and dies immediately, usually with a blinking theft light on the cluster.
These are the least expensive Super Duty keys to replace. The blank is inexpensive, the cut is straightforward, and the programming session through the OBD-II port is short. If your truck cranks but will not stay running and the security indicator is flashing, that is PATS behavior, and we break the symptom down separately in our Ford PATS anti-theft light guide.
Remote-head keys: everything in one housing
Later Super Duty trucks moved to an integrated remote-head key, where the cut blade, the transponder chip, and the lock, unlock and panic buttons all live in a single molded head. Some trims added a switchblade-style flip housing. The mechanical cut works the same way it always did, but you are now paying for remote-entry electronics bonded to the key, which is why a remote-head key costs meaningfully more than a bare transponder key for the same truck.
Push-button start: proximity fobs and no cylinder at all
Higher Super Duty trims, and most later ones, use a proximity smart fob with push-button start. There is no ignition cylinder to turn. The truck listens for the fob inside the cabin, and if it hears a valid one it lets you press the button. A thin emergency blade hides inside the fob body for the door lock, in case the truck's battery or the fob's battery is dead.
Proximity fobs carry the most electronics and sit at the top of the price band. They also introduce a symptom that is not a lost-key problem at all: a "key not detected" message when the fob is sitting right there in the console. That is usually a dead fob battery or a detection issue, and it is worth ruling out before assuming you need a whole new fob.
What all keys lost costs in Fort Worth (2026)
Every figure below is the all-in mobile price — key hardware, cutting, and programming, performed wherever the truck is sitting. The spread inside each row comes from model year, trim, and how many keys we are making in the same visit.
| Super Duty key type | Typical trucks | Fort Worth locksmith price (2026) | Typical on-site time |
|---|---|---|---|
| Transponder blade key, all keys lost | Older F-250 / F-350 with turn-key ignition | $210–$390 | 45–75 min |
| Remote-head or flip key, all keys lost | Mid-generation F-250 / F-350 / F-450 | $290–$520 | 60–90 min |
| Proximity smart fob, all keys lost | Push-button Super Duty trims | $420–$850 | 60–120 min |
| Spare key added while one still works | Any Super Duty with a working key | $150–$430 | 25–50 min |
| Second matched key, same visit | Any of the above, cut and enrolled together | $95–$280 each | Adds 10–25 min |
The single biggest lever in that table is whether a working key still exists. With a key in hand the technician can duplicate a known-good cut and add the new key to a system that is already unlocked. With nothing at all, the job becomes reconstruction: pull the key code from the VIN, cut from code rather than by copying, and put the immobilizer through a complete programming session with the truck's security module. The step-by-step version of that process lives in our all-keys-lost VIN-to-new-key walkthrough.
The second lever is batching. Two keys made on one visit cost far less than two keys made on two visits, because the diagnostic setup and the drive time are shared. If you are already paying for an emergency all-keys-lost call, adding the spare right then is the cheapest spare you will ever buy.
VIN and proof of ownership: what we check and why
An all-keys-lost job is the one situation where a locksmith is, functionally, manufacturing access to a vehicle from nothing. That is exactly why the verification step is not optional.
Legitimate access to factory key codes and security data runs through the National Automotive Service Task Force's Vehicle Security Professional program (nastf.org), which vets technicians and keeps an audit trail on every code request. When our technician asks for your paperwork, that is the system working as designed, not a stall.
Have these ready before the truck arrives:
- The VIN. On a Super Duty it is on the driver-side door jamb sticker and readable through the base of the windshield on the driver's side.
- Photo ID for whoever is meeting the technician.
- Proof of ownership. Registration, title, or a current insurance card matching the name on the ID.
- A work order or authorization letter if the truck is titled to a company and the person on site is not the owner or an officer. A photo of a letterhead note on a phone is fine.
- Any surviving key, even a broken or dead one. It sometimes shortens the job and lowers the price.
The Federal Trade Commission's consumer guidance (consumer.ftc.gov) and NHTSA's vehicle theft prevention material (nhtsa.gov) both make the same underlying point: the verification step is what stops someone else from having a key cut to your truck. Texas locksmiths are licensed under the DPS Private Security Program (dps.texas.gov), and you are entitled to ask about that before anyone opens a door.
Why a loaded work truck gets keyed where it sits
A Super Duty is a bad tow candidate and a worse dealership candidate. Consider what actually happens if you call a tow truck instead of a locksmith.
First, you are paying to move a vehicle that weighs three tons empty and considerably more with a bed full of welding gear, and heavy-duty towing is priced accordingly. Second, if the truck is hitched to a trailer, that trailer now needs its own solution. Third, you are leaving your tools in a lot overnight. Fourth, the dealer schedules you when there is an opening, which for a key job is frequently not today. Add it up and the tow-plus-dealer route routinely costs more than the key itself and puts the truck out of service for a day or more.
Mobile service inverts the whole sequence. The technician drives to the truck, verifies ownership, pulls the key code from the VIN, cuts the blade on site, connects to the diagnostic port, and enrolls the new key into the truck's immobilizer. Push-button trucks follow the same pattern through the keyless module. You start the truck, test the doors and remote, and pay when it runs. Most jobs finish in 45 minutes to two hours, and we run 24/7 — the 4:30 a.m. call before a crew heads out to a site is completely normal here.
If your Super Duty is one truck in a mixed fleet, the same visit logic applies across vehicles. We cover that scenario in more depth in our Ford Transit and E-Series van key guide, and the batching advice there transfers directly to a yard full of pickups.
Where we tell people to slow down
Three honest boundaries are worth stating plainly.
Do not buy a fob online first. Many used proximity fobs are permanently married to their original vehicle and cannot be re-enrolled at all. Counterfeit automotive electronics are a real and documented problem. If a customer-supplied fob will not program, the visit is still billable, so the savings usually evaporate.
The newest model years are a tech-confirms conversation. Ford, like most manufacturers, keeps tightening the security around key enrollment on current-year trucks, and some late-model configurations require additional steps or manufacturer-side authorization. We will tell you honestly on the phone whether your year and trim is routine or whether a technician needs to confirm your exact setup before quoting a firm number.
Sometimes it is not the key. If a known-good key stopped working, if the theft light behaves erratically, or if the truck cranks with no response at all, the fault may live in a module rather than in the key. That is a diagnose-then-quote service, not a flat-rate key job — our ECU and module programming service covers that lane. Likewise, a key that goes in but will not turn is usually a worn cylinder rather than an electronic problem, and the ignition band runs $150–$550 depending on the truck.

Frequently Asked Questions
I lost my only Ford key in Fort Worth. What is my fastest option?
Call a mobile automotive locksmith with your VIN. A technician can usually reach the truck within the hour, verify ownership, cut a key from the factory code, and program it on site. Total time from the call to a running truck is commonly one to three hours, versus a tow plus a dealership appointment that often runs into the next day.
How much does all keys lost cost on an F-250 or F-350?
In Fort Worth in 2026, expect roughly $210 to $390 for an older transponder blade key, $290 to $520 for a remote-head key, and $420 to $850 for a push-button proximity fob when no working key remains. The full car key band runs $150 to $850, and your exact number depends on model year, trim and key type.
What paperwork do I need for an all-keys-lost job?
Photo ID plus proof that the truck is yours — registration, title, or a current insurance card in your name. If the Super Duty is titled to a company and you are not the owner or an officer, add a work order or a short authorization letter on company letterhead. A phone photo of that letter is acceptable.
Can you make a Super Duty key at a job site or on the side of the road?
Yes. Everything a Super Duty key job needs travels in the van: code retrieval, key cutting, and immobilizer programming. We work in driveways, gravel yards, construction sites and shoulder pull-offs across the Fort Worth area, 24 hours a day.
Should I just have the truck towed to the Ford dealer?
Rarely worth it. Heavy-duty towing is expensive, a hitched trailer complicates it further, your tools sit in a lot overnight, and the dealer works on its own schedule. A mobile locksmith produces the same working key at the truck, usually the same day.
Will a new key also work my door locks and remote?
Yes. A key cut from the factory code operates the doors mechanically, and a remote-head key or proximity fob is programmed for lock, unlock and panic during the same visit. We test doors, remote functions and a full start cycle before we consider the job finished.
