Ford has been building immobilized vehicles longer than most manufacturers, which means the Explorer and Expedition population in Arlington spans an enormous technological range — from bladed transponder keys in older trucks to proximity fobs in current ones. The procedure differs. The principle does not.
How PATS decides whether your engine may start
PATS stands for Passive Anti-Theft System, and it has been Ford's immobilizer approach across generations. A transceiver reads the key's transponder, a module compares the response against a list of authorized keys, and only a match permits fueling and starting. On proximity vehicles, antennas around the cabin do the detecting instead of a ring at the ignition, but the module logic is the same.
Three consequences follow from that design.
- Keys are data, not just metal. New keys must be written into the module, which is why this belongs with our car computer and immobilizer programming work.
- A working key is an access credential. With one present, the module accepts an add-key session in minutes. With none, lawful access must be established the long way — and that is the entire price gap.
- The blade never stops mattering. Even on push-button trucks, the emergency blade inside the fob opens the door when a battery fails, so it gets cut as part of the job.
Explorer and Expedition: two different failure stories
Explorer: the volume vehicle
The Explorer is everywhere in North Texas, across every generation and every trim. That volume means we see the full spectrum: fifteen-year-old trucks on a single worn bladed key, mid-generation trucks with remote-head keys held together by tape, and late-model proximity trucks whose second fob went missing during a used-car sale.
Expedition: the long-haul family truck
Bigger, kept longer, and used harder. The Expedition typically arrives as a second or third owner vehicle whose key history nobody can reconstruct. That is the version of this job where erasing unknown fobs is worth as much as originating new ones.
"The Explorer we tow-proof most often is a used one where the sale came with a single key and a promise about a second." — Arlington Locksmith service desk

Ranges depend on the model year and how much module access the specific truck requires. The firm number is confirmed on site before work begins.
What happens during the visit
- Verification. Photo ID plus title, registration, or insurance matching the vehicle identification number. This step is not optional and it never should be.
- Access. If the truck is locked, it is opened without damage — routine car lockout work.
- Blade cutting. The mechanical blade is cut from the vehicle identification number or by decoding a door lock, on site.
- Origination. Lawful access to the security module is established and the authorized key list is rebuilt from zero.
- Testing. Lock, unlock, liftgate, panic, proximity detection at every zone on a push-button truck, and a real engine start before we call it done.
One to two hours. Adding a spare is usually half an hour, which is the entire argument for handling it before the last key disappears.
Ford-specific things worth knowing
MyKey settings survive a key change
Ford's configurable driver-restriction feature lives in the vehicle, not in the key. Programming new keys does not automatically clear a restricted-driver configuration, so if a used truck arrives with speed or audio limits enabled, that is a separate conversation from the key work.
Older trucks and the two-key programming myth
There is a long-standing belief that Ford requires two working keys to add a third. That reflects a specific onboard procedure some generations offer to owners, not a limitation of professional equipment. With proper tooling a single working key is enough, and with no working key origination is still possible on the large majority of these trucks.
Aftermarket remote start
Explorers and Expeditions in this market frequently carry remote-start modules installed years ago. They occasionally complicate a session and are rarely fatal, but mentioning one on the phone means the technician arrives expecting it rather than discovering it.
Worn ignition versus dead key
If the key turns but nothing happens, that is often an electrical or immobilizer question. If the key barely turns or has to be wiggled, that is mechanical wear and belongs with our ignition repair work rather than key programming. Diagnosing which one you have before dispatch saves everybody a wasted trip.
The honest boundary
Most Explorers and Expeditions on Arlington roads are ordinary mobile work. There is a narrow band of very new vehicles across the industry where factory-controlled procedures apply and no independent tool set legitimately performs them, and where a specific truck falls into that band the dealer is the right answer. We say so on the phone instead of charging for a trip that cannot finish. Our dealer versus locksmith comparison covers the broader trade-offs.
Automotive security work is regulated work. Texas locksmiths operate under the Texas Department of Public Safety Private Security Program, and the secure data channels behind immobilizer procedures are coordinated through the National Automotive Service Task Force. The reason that structure exists is documented by the NHTSA: electronic immobilization is among the most effective standardized anti-theft measures ever deployed, so access to it is deliberately controlled.
Where in Arlington do you do this?
Wherever the truck is parked. Our technicians cover driveways across west Arlington and south Arlington, workplace lots in Pantego, retail parking at The Parks Mall, and the neighborhoods around Lake Arlington.

What actually happens to the price, and why
Owners reasonably want to know why one key costs $180 and another costs $560 on the same truck, so here is the breakdown without the mystery.
The hardware. A bladed transponder key is a cheap physical part. A proximity fob is a small radio with a battery, an antenna, an encrypted chip, and a hidden blade. That is a real difference in acquisition cost before anyone touches the vehicle.
The cutting. Cutting to factory code from the vehicle identification number is more work than duplicating an existing key, and it produces a better result. On a truck whose only key has been worn smooth for a decade, cutting to code is the only sensible option, because duplicating a worn key copies the wear into the new one.
The authorization. This is the big one. With a working key present, the module accepts an add-key session in minutes. With nothing working, lawful access has to be established the long way, and that time is most of the price difference between the two rows in the table above.
The testing. Every function verified before the technician leaves: lock, unlock, panic, liftgate, proximity zones, real engine start. This is quick but it is not optional, and a job that skips it is a job that comes back.
None of those four are negotiable levers. The only lever you actually control is the third one, and you control it by deciding whether to call before or after the last key disappears.
What we ask on the phone, and why it matters
Five questions, and each one changes either the price or whether we should come at all.
- Year, make, and model. This determines the key generation, the procedure, and whether the vehicle falls inside the narrow band described above.
- Does any key still work? The single largest price variable, by a wide margin.
- Key slot or start button? Distinguishes a bladed or remote-head key from a proximity fob.
- Where is the truck parked, and is it locked? Determines whether a car lockout step is part of the visit.
- Do you have the title, registration, or insurance card? Verification happens before anything is cut, so it is better to find the document now than while a technician waits.
A quote given without those five answers is not a quote. It is a number designed to win a phone call, and it grows once somebody is standing at your vehicle.
Frequently Asked Questions
How much does Ford all-keys-lost cost in Arlington?
As of August 2026, full PATS origination on a Ford Explorer or Expedition in Arlington generally runs about $300 to $560, while adding a spare when one key still works generally runs about $180 to $340. The gap reflects the extra access work required when nothing exists to authorize the session, and the figure is confirmed before dispatch.
What is Ford PATS and why does it matter?
PATS is the Passive Anti-Theft System, the immobilizer Ford has used for decades. A transceiver reads the key, a module compares the response against an authorized list, and only a match allows fueling and starting. Because the list lives in a module rather than in the lock, replacing keys is an electronic procedure rather than a metal-cutting one.
Do I need a tow if I lost every key to my Explorer?
Almost never. PATS origination happens at the vehicle through the diagnostic port, so an Explorer in a driveway or an Expedition at a workplace stays where it is parked. Towing is a constraint of fixed-location shops rather than a technical requirement, and avoiding it typically saves more than the tow bill by itself.
How long does all-keys-lost take on a Ford SUV?
Usually one to two hours on site. That covers ownership verification, cutting the mechanical blade from the vehicle identification number, establishing lawful access to the security module, originating the key list, and verifying every function. Adding a spare while a key still works is normally a thirty to forty-five minute visit instead.
What paperwork do I need before you cut a Ford key?
A photo ID plus proof the vehicle is yours, which can be the title, the current registration, or an insurance card showing the vehicle identification number. This is standard across the industry for immobilizer work and it protects the owner as much as the locksmith. Verification happens before any key is cut or written, never after.
Does programming new keys disable the ones a previous owner kept?
It can, and on a used Expedition that is often the real reason for the call. All-keys-lost origination rebuilds the authorized list and can exclude unknown fobs. Straightforward spare-key addition leaves every previously registered key working. Tell us which outcome you want and the module is configured accordingly.
My Explorer has a push-button start. Does that change anything?
It changes the hardware, not the principle. A push-button Explorer uses a proximity fob with an emergency blade tucked inside, and the fob is authenticated by antennas around the cabin instead of a transceiver ring at the ignition. The blade still gets cut, because it is what opens the door the day a fob battery dies.
