Digital Car Key Cost in Frisco, TX (2026): Phone Keys, Card Keys and the Backup Fob

Digital Car Key Cost in Frisco: The Short Answer

As of September 2026, setting up a digital car key on your phone should cost you nothing in most cases - it is done through the manufacturer's app, the car's own menus, or your phone's wallet. The money in a digital key system is in the physical credentials behind it: a backup smart key fob typically runs $120 to $500 with us, an enrolled card key is priced like a spare in the same band, and if the car's key module has to be reprogrammed after a fault, that falls in our $200 to $800 programming band. A lockout when the phone is dead and nothing else works is $75 to $200.

In other words, the phone key is cheap. Losing access to the car when the phone key is your only key is not. This guide explains where the costs sit, brand by brand, and how to set things up so you never pay the expensive version.

What a "Digital Car Key" Actually Is

The phrase covers three different things, and they are priced very differently.

A phone key. Your phone stores a credential that the car recognizes over Bluetooth Low Energy, NFC, or ultra-wideband. Tesla, Hyundai, Kia, Genesis, BMW, Mercedes-Benz, Lincoln, Ford, Rivian, Lucid, Polestar and others offer versions of this. Some live in the manufacturer's app; some live in Apple Wallet or Google Wallet under the industry's shared digital key standard. We explain the difference between the radio technologies in our guide to UWB versus Bluetooth phone keys.

A card key. A thin NFC card you tap on the door pillar or handle and place on a reader to drive. Tesla made the format familiar; Hyundai, Kia and Genesis use similar cards on several models.

A physical smart key. The fob. On nearly every car that offers a phone key, the fob is still the master credential that everything else hangs off. That is the part people forget, and it is where almost all of the real cost lives.

The 2026 Digital Key Price Table

These are our service bands. The final figure depends on the car and the job, and we confirm it against your VIN before anybody is dispatched.

Digital key job	Our price band	Is it usually a locksmith job?	Notes
Setting up a phone key on a car with a working fob	Free (owner setup)	No	Done in the app, the car's menus, or the phone wallet
Re-provisioning a phone key after a new phone	Free (owner setup)	No	Usually requires a working enrolled key
Adding a backup smart key fob	$120 - $500	Yes	The most important line item on this page
Adding or replacing an NFC card key	$120 - $500	Often	Priced like a spare; some brands restrict to dealer
All keys lost (phone gone, no working fob)	$120 - $500	Yes, where supported	Upper end of the band; proof of ownership
Key or immobilizer module reprogramming	$200 - $800	Yes	Only when the fault is in the car
Lockout with a dead phone and no other credential	$75 - $200	Yes	Damage-free entry; the phone still needs charging

Two honest caveats. First, a few newer platforms restrict card key or all-keys-lost enrollment to the manufacturer or franchise dealer; when that is the case we say so on the phone, before dispatch. Second, nothing in this table is a claim about what a dealer charges. We only publish our own bands.

Brand by Brand: Where the Cost Actually Sits

Tesla

Tesla's phone key, key card and optional fob are the model most people know. The phone key is set up in the Tesla app. Adding a key card or fob requires an already-authorized credential inside the car. The expensive scenario is a Tesla owner whose only working credential was the phone and whose cards are lost. We cover that specific case in our guide to Tesla Model 3 and Model Y all keys lost, and the full Tesla price picture in our Tesla key credentials cost guide.

Hyundai, Kia and Genesis

The Hyundai group offers a digital key on a growing list of models, including the IONIQ 5 and IONIQ 6, the Kia EV9, and much of the Genesis lineup. On several models, an NFC card key comes with the car. A physical smart key is still the credential you need to set things up again after a phone change. Our guides to the Kia EV9 digital key and spare and the Hyundai IONIQ 5 and IONIQ 6 go deeper on those two platforms, and our Genesis key replacement cost guide covers the Genesis side.

BMW

BMW Digital Key and Digital Key Plus let a compatible iPhone or Android phone act as the key, with Digital Key Plus using ultra-wideband for true hands-free entry. The phone side is set up through the My BMW app. The physical BMW key, or a key card on some models, still underpins the system. See our BMW Digital Key Plus guide.

Mercedes-Benz

Mercedes me Digital Key works on selected models with compatible phones. Like BMW, the phone key sits on top of the physical key, not instead of it. Our Mercedes me digital key guide covers setup and the limits.

Ford and Lincoln

Phone As A Key is available on many Lincoln models and on some Ford vehicles, including the electric ones. It is set up through the brand app and requires the vehicle to have the feature enabled. Our Lincoln and Ford phone-as-a-key guide explains the setup and what happens if the phone is lost.

Rivian, Lucid and Polestar

These EV-native brands built the phone key in from the start, with key cards and fobs as backups. Enrollment of new physical credentials is more manufacturer-controlled than on older brands, which affects what an independent locksmith can do. Our Rivian, Lucid and Polestar cost guide covers each brand, and our new Lucid Gravity key guide covers Lucid's SUV.

Why the Backup Fob Is the Line Item That Matters

Every digital key system we work on shares one design principle: you prove you are the owner with a credential the car already trusts, and then you add new ones. That is a sensible security design. It is also why the fob matters so much.

When a household runs entirely on phones, a single bad day can remove every trusted credential at once. A phone is lost at a game at Toyota Stadium, a second phone is on a trip, the card key is in the other car, and suddenly nothing the car trusts is within reach. At that point, getting back in is no longer a free app setup. It becomes an all-keys-lost job, which is the most expensive job on the table above, and on a few platforms it becomes a dealer-only job.

A backup fob, bought while everything still works, costs a fraction of that. It is the cheapest insurance in the whole system.

"People think the phone key replaced the fob. It didn't. It sits on top of the fob. The calls that cost the most are the ones where the fob went in a drawer three years ago and nobody knows which drawer." - a Frisco Car Key technician

Common Digital Key Problems and What They Cost

"My phone key stopped working after I got a new phone"

This is the most common call we get about digital keys, and it is usually free to fix. The credential lives on the old phone and has to be re-provisioned on the new one through the brand app or wallet. The catch is that most systems need a working enrolled key present to do it. If you have the fob, you are fine. If you do not, see the backup fob section above. Our guide to a phone key that stopped working after a phone upgrade walks through it.

"It worked yesterday and the car ignores the phone today"

Check the phone first: Bluetooth on, the app allowed to run in the background, battery-saver settings not killing it, and the phone's own battery not critically low. If the car recently took an over-the-air update, the key may need to be re-paired. We cover that exact pattern in EV key stopped working after a software update. None of this should cost locksmith money unless the car's module is genuinely at fault.

"The whole car is dead and the phone key does nothing"

On an EV, the doors, readers and computers run on a separate 12-volt battery, not the traction battery. If the 12-volt side is flat, the phone key cannot wake the car no matter how much range the app shows. That is a power problem, not a key problem, and we explain it in EV 12-volt battery dead and the phone key won't work.

"I sold or bought a used EV and the old owner's key still works"

Removing old credentials is a security issue as much as a convenience one. Most brands let you view and delete enrolled keys from the car's menus. We cover the process, and what to do when it does not work, in removing a previous owner's key access from a used EV.

Sharing Digital Keys Without Paying for Them

One of the genuine advantages of a phone key is that you can share it. Most brands let you send a limited key to a family member, a teenager, or a valet, with restrictions on speed or time on some platforms. That is free and usually better than buying another physical credential for occasional use. We cover the details in sharing a digital car key with family or a valet.

What sharing does not do is replace a backup fob. A shared key depends on the owner's account and on a working primary credential. If the primary goes, shared keys generally go with it.

How to Set Up a Digital Key So It Never Gets Expensive

Keep one physical fob enrolled and stored somewhere you can find it. Not in the car.
Put a card key in your wallet if your car supports one. It is a second backup that fits where the phone lives.
Know how to view enrolled keys in your car's menus, and check the list once or twice a year.
Re-provision the phone key before you trade in the old phone, not after.
Watch the 12-volt battery on an EV. A phone key cannot wake a car with no 12-volt power.
Share keys through the app instead of lending the primary phone or fob.

When a Digital Key Problem Is Really a Module Problem

Occasionally the fault is in the car: a key or body control module that has dropped its learned credentials after a low-voltage event, an antenna that has failed, or a software fault after a repair. In those cases the fix is programming, not a new key, and it sits in our ECU and module programming service. A physical key replacement, where it is needed, sits in smart key programming.

On some Hyundai, Kia and Genesis models, a module fault shows up as a "Check Smart Key System" warning; our guide to that warning explains what it means.

Security: Why Enrollment Requires Proof

Every all-keys-lost job, digital or not, requires proof of ownership, normally a photo ID matching the registration or title. The National Automotive Service Task Force exists in part to keep vehicle security information in the hands of vetted professionals. The Insurance Institute for Highway Safety and the National Highway Traffic Safety Administration both publish material on keyless theft and anti-theft technology that is worth a read for any digital key owner. Texas locksmiths are licensed through the Department of Public Safety's Private Security Program.

Frequently Asked Questions

How much does a digital car key cost to set up?

In most cases, nothing. Phone keys are set up through the manufacturer's app, the car's own menus, or your phone's wallet, and that is owner setup rather than paid service. As of September 2026, the costs in a digital key system sit in the physical credentials behind it: a backup smart key typically runs $120 to $500 with us, and card keys are priced like a spare.

Do I still need a key fob if I use my phone as a key?

We strongly recommend keeping at least one physical fob enrolled. On nearly every system, the fob or another trusted credential is what you need to set the phone key up again after a phone change or reset. Without one, a lost phone can turn into an all-keys-lost job.

I lost my phone and it was my only key. What does it cost?

It depends on the car. If a card key or fob is available, re-provisioning the phone is free. If not, getting a new credential enrolled is an all-keys-lost job, generally at the upper end of our $120 to $500 band, with proof of ownership required. A few newer platforms restrict that to the manufacturer or dealer; we check your VIN before dispatch.

Can a locksmith set up my phone key?

We can help you through it and make sure the car has a working physical key enrolled, but the phone credential itself is provisioned through your manufacturer account or wallet. You should not pay a locksmith fee for the phone setup alone.

How much is a replacement card key?

A card key that has to be enrolled to the car is priced like a spare, within our $120 to $500 band. Some brands restrict card key enrollment to their own service network; we will tell you on the phone if yours does.

Why did my phone key stop working after an update?

Over-the-air updates sometimes require phone keys to be re-paired, and some phone settings, such as aggressive battery saving, stop the app from running in the background. Check the phone settings and re-pair through the app. If that fails and your fob works, the fault may be in the car's module, which is a programming job.

Does a dead 12-volt battery affect the phone key?

Yes. On an EV, the doors, readers and computers run on the 12-volt battery, so a flat 12-volt battery stops the car from waking for any key, including the phone. The traction battery's range does not help. That is a power problem to solve before any key work.
