Most Bronco and Ranger owners call us for one of two reasons. Either the fob has stopped doing something it used to do, or they have finally noticed the truck came with exactly one key. Those are different problems with very different price tags, and telling them apart before you spend money is worth a few minutes. Southlake TX Locksmiths programs Ford keys at your vehicle. Call or text (972) 573-7978.

Quick Answer

If your Ford fob has stopped working, the cause is a dead coin cell far more often than a failed fob. Replace the battery first — it is a few dollars and takes two minutes. If the remote still does nothing after a fresh battery, the fob itself or the vehicle's receiver is the next suspect, and that needs diagnosis rather than a guess.

If you simply want a second key, a spare on a 2021-onward Bronco or a 2019-onward Ranger runs $260 to $460 for a proximity smart key, or $190 to $330 for a remote head key on trims that use one. All-keys-lost on either truck runs $380 to $650. The difference between those two numbers is the entire argument for getting a spare before you need one.

When the fob stops working

Work through these in order. The list is arranged by how often each one turns out to be the answer.

The coin cell is dead. Ford fobs use a common flat battery that lasts roughly three to five years. The failure is rarely sudden — range shrinks first, so you find yourself standing closer to the truck each week, then one morning nothing happens. If your range has been getting worse, this is almost certainly it.

The fob got wet. A fob that went through a wash cycle, a lake day or a rainstorm in a jacket pocket often works intermittently for weeks before quitting for good. Corrosion creeps across the board slowly. If yours has been soaked, our guide on how to fix a wet key fob covers whether it is worth saving or whether you are better off with a fresh one.

The truck battery is low. On push-button vehicles a weak battery produces symptoms that look exactly like a key fault — passive entry stops responding, the truck refuses to authorize, and the dash may throw a message about the key not being detected. Charge and retest before concluding anything about the key.

A button has physically failed. Buttons wear. If lock works but unlock does not, and a fresh battery changed nothing, the contact under that one button has likely given out. Some fob shells can be replaced while keeping the working electronics inside, which is cheaper than a new programmed key.

The receiver or a module is at fault. Least common, but real. If a known-good second fob also fails, the problem is on the truck side, not in your hand. That is a diagnosis, not a key sale.

Passive start still works when the fob battery is dead

Worth knowing before you call anyone at 11pm. On Ford push-button vehicles there is a backup start method that does not require a live fob battery — the fob is held in a specific location so the truck can read it at very short range, usually on the steering column or in the center console. The exact spot varies by model and year, so check the owner's manual section on key fob battery replacement, which describes it for your specific truck.

There is also a mechanical emergency blade hidden inside most Ford proximity fobs. It opens the driver's door. It will not start the truck. That distinction catches people out constantly.

What a Bronco or Ranger spare key involves

Ford's immobilizer system is PATS, and it has been through several generations. Current Broncos and Rangers use a modern implementation where the key credential is authorized against the vehicle rather than simply cloned.

Ownership verification. Registration, title or an insurance card showing the VIN, plus a photo ID matching that name. Programming a key to a truck is exactly what a thief would want done, so this step is not optional at any reputable shop.

VIN and configuration check. We confirm which key type your specific trim expects. This matters more on Ford than on some makes, because the same model year can ship with a bladed remote head key on one trim and a proximity smart key on another. Ordering the wrong one wastes a trip.

Blade cutting. The emergency blade or the bladed key is cut to your truck, normally by decoding the existing lock rather than trusting a code that may not match a replaced cylinder. If you are curious how modern high-security blades differ from the old flat keys, our explainer on how laser cut keys work covers it.

PATS programming. The new key is authorized to the vehicle. With a working key present this is quick. With no working key at all it takes considerably longer and follows a different procedure.

Function verification. Start, lock, unlock, panic, tailgate release, remote start if equipped, and on proximity trims both passive entry and passive start. A key that starts the truck but will not unlock it is not finished work.

Why the spare is so much cheaper than the emergency

Adding a key while one still works is a routine, scheduled job. Losing every key turns it into an emergency, at whatever hour and location the loss happened, and the procedure itself is longer.

On a Bronco or Ranger the gap is usually $150 to $250. That is the real price of not having a spare — plus the day you lose to it. If you own one of these trucks and have a single key, that is a single point of failure on a vehicle you rely on.

For the general version of this math across every make, see what actually drives transponder key pricing.

Bronco, Bronco Sport and Ranger are not the same job

Three trucks that share a name family and do not share a key architecture.

The Bronco (2021 onward) is body-on-frame and shares much of its platform with the current Ranger. Most trims use a proximity smart key.

The Bronco Sport (2021 onward) is a unibody vehicle on an entirely different platform. It is a different key job with different pricing, so tell whoever you call which one you have — the two get confused on the phone constantly.

The Ranger returned to the US market for 2019 and was redesigned for 2024. Earlier Rangers (through 2011) are a much older PATS generation and are considerably cheaper to key.

If your Ford is an F-150 Lightning rather than a Bronco or Ranger, the F-150 Lightning key replacement guide covers that truck specifically, and our Ford PATS programming overview covers the lineup more broadly.

Doing this at your truck instead of at a dealer

We are mobile, which matters most in the scenario where it matters most. A truck with no working key cannot be driven to a dealership, so that route begins with a tow that lands before any key work starts. Mobile service reverses the order — the technician comes to the immobile vehicle, in a driveway in Southlake, a job site in Keller, or a parking lot in Grapevine.

On price, dealer key work is generally structured around parts at list. The gap on a Ford is typically smaller than on a European luxury car, but it is still real, and the tow avoided is often the larger number. When a dealer-supplied key genuinely is the better answer for an unusual configuration, we will say so instead of selling you something that disappoints. Our note on what we can key on site by make is an honest inventory of where that line falls.

Frequently Asked Questions

My Ford key fob is not working at all — what should I try first? Replace the coin cell battery. It is the cause more often than everything else combined, and it costs a few dollars. If a fresh battery changes nothing, the next suspects are water damage inside the fob, a low truck battery, or a receiver fault — and those need diagnosis rather than a replacement key bought on a guess.

Can I still start my Bronco if the fob battery is dead? Yes. Ford push-button vehicles have a backup method where the fob is held at a specific spot, usually on the steering column or in the console, so the truck can read it at very short range. The exact location varies by model, so check the owner's manual section on fob battery replacement.

How long does a Ranger spare key take? Usually forty-five minutes to ninety minutes on site with a working key present. All-keys-lost typically runs ninety minutes to two and a half hours depending on the truck and trim.

Is a Bronco Sport key the same as a Bronco key? No. Despite the shared name they are entirely different vehicles on different platforms with different keys and different pricing. Say which one you have when you call so the right key comes out with the technician.

Do you come to the truck, or do I have to bring it somewhere? We come to you across Southlake, Colleyville, Keller, Grapevine, Westlake and Trophy Club. That is the point of mobile service, and it matters most when the truck cannot be driven.

What documents do I need for a Ford key? Proof the vehicle is yours — registration, title or an insurance card showing the VIN — plus a photo ID matching that name. For company trucks or drivers who are not the titled owner, call ahead so authorization can be handled before dispatch.
