Toyota Tundra & Sequoia All-Keys-Lost Key Replacement in Granbury, TX

Tundras and Sequoias are the tow rigs of choice for a lot of Hood County families — boat on the back, gear inside, three hundred thousand miles ahead of them. Which makes losing the last key an unusually expensive kind of quiet. Call or text (817) 214-2934 and we will bring a new one to the vehicle.

Quick Answer

Yes, a mobile automotive locksmith can make a new Toyota Tundra or Sequoia key with no original key at all. We originate the cut from the VIN and pair the key or smart fob to the vehicle's immobilizer at your Granbury or Hood County location — no tow to a Toyota dealer. As of July 2026, transponder all-keys-lost work here generally runs $185–$325, and proximity smart-key work $150–$350 depending on the fob, quoted by VIN before we dispatch.

Toyota's Immobilizer, Generation by Generation

Which system your vehicle uses determines the procedure and the price, and the model year is the fastest way to tell.

Early transponder era. A chip in the key head authenticates to the engine immobilizer. If it does not match, the engine cranks and will not run, and the security indicator stays lit. All-keys-lost means originating the blade and writing a new key into the immobilizer.

Later blade keys with integrated remotes. Same authentication principle, with the remote-entry functions built into the key. Symptoms of failure are identical.

Smart key / push-button era. A proximity fob is detected inside the cabin and the start button works. There is no key slot. An emergency blade lives inside the fob for door access when the fob battery dies, and most of these vehicles also allow a backup start by holding the fob against or near the start button. If that backup works, your vehicle is healthy and the fob's transmitter is weak — a much cheaper conversation.

The newest generations. Later Toyota trucks and SUVs run tighter security architecture, and some operations require credentialed access or, on certain builds, remain manufacturer-only. We check the VIN before we quote so you are not told one thing on the phone and another in your driveway.

Granbury Pricing

Dealer alternatives for equivalent key work commonly start at $200–$600 and require your vehicle at their service drive. There is no Toyota dealer inside Granbury, so that route also means moving an undrivable truck out of the county. Mobile locksmith pricing here typically runs 40–60% below dealer for the same services. See the full dealer cost comparison.

Why All-Keys-Lost on a Tow Vehicle Is Worse Than It Sounds

A dead commuter car in a driveway is a scheduling problem. A dead tow vehicle is a chain reaction.

The trailer is attached. Boat, stock trailer, equipment trailer — it is not going anywhere without the truck, and a tow operator now has two things to deal with instead of one.

The location is rarely convenient. Ramps around Lake Granbury, lease roads past Bluff Dale, hay fields near Tolar, and gates off Highway 377 are all normal call locations for us. None of them have a street number.

The cargo has a clock. Livestock, a boat in the water, or a job that starts at 7 AM all make "we can see it Thursday" an unacceptable answer.

Cell coverage varies. In parts of the county you will get one bar. Send us your location while you have signal, not after you have walked to find some.

That combination is the entire reason mobile service exists in a rural county. Details on drive expectations by community are in our Hood County response-time guide, and if it is after hours, see emergency car key replacement in Granbury.

What We Need Before We Roll

1. VIN. Driver-door jamb sticker, base of the windshield, or your insurance card. A photo texted with your request produces a faster and more accurate quote than reading digits aloud on a bad connection.
2. Proof of ownership. Registration, title, or insurance in your name plus matching photo ID. Company truck? Registration in the business name plus your ID, or a signed fleet letter. Texas locksmiths operate under the Texas Department of Public Safety Private Security Program, and this step is required for key origination — never optional.
3. Model year and whether it has push-button start. A key slot and a start button are different jobs at different prices.
4. Honest key count. No working key at all, or one that still works? Understating this only produces a quote that changes on arrival, which helps nobody.
5. A precise location. Cross street, ramp name, gate number, or a dropped map pin.

How the Job Runs

Verification. Documents checked against the VIN at the vehicle.

Entry if needed. If the vehicle is locked and the key is gone, damage-free entry comes first — see car lockout service.

Origination. The mechanical cut is produced on site from VIN-derived key code data. On smart-key vehicles this is the emergency blade inside the fob.

Programming. The transponder or fob is written into the immobilizer. Where the vehicle's security gateway requires credentialed access, that runs through the NASTF Vehicle Security Professional program — the sanctioned channel through which independent shops obtain manufacturer-restricted security data.

Testing. Doors, ignition or start button, remote functions, passive entry on smart-key vehicles, and the dead-fob backup procedure. We show you the backup before we leave.

The spare. We will offer a second key at the same visit for a fraction of what a separate call costs. Every all-keys-lost job we run exists because that offer was declined at some point in the past.

Typical time on site: 45 to 90 minutes for transponder vehicles, longer for some smart-key procedures.

Why These Trucks Outlive Their Key Plans

There is a specific reason Tundras and Sequoias produce more all-keys-lost calls per vehicle than most of what we service, and it is not owner carelessness. It is longevity.

A vehicle that stays in one family for twelve or fifteen years accumulates key history that nobody tracks. The original pair leaves the dealer together. One goes to a spouse, then to a teenager, then into a tackle box. A replacement gets made somewhere along the way and works intermittently. By year ten the household genuinely does not know how many working keys exist, where they are, or whether the "spare" in the kitchen drawer has ever actually started the truck.

Then the surviving key goes into the lake, and the drawer key turns out to be for the vehicle they sold in 2019.

Two practical habits fix this, and both are free:

Test your spare twice a year. Not just the doors — actually start the engine with it. A spare that unlocks but does not start is a transponder that was never programmed, which is a surprisingly common outcome from cheap key-copy services. Finding that out on a Tuesday is fine. Finding it out at a ramp is not.

Know how many keys exist. If the answer is "one, I think," you have an all-keys-lost call in your future and only the date is unsettled.

Second-generation and older trucks are the ones most likely to be in this position, and they are also the cheapest to make a spare for. The vehicles that most need a second key are the ones where a second key costs the least.

Common Tundra and Sequoia Symptoms We See

Cranks strong, will not run, security light on

Immobilizer refusal. The engine is mechanically fine and being denied. This is a key or security-system problem, not an engine problem.

Fob unlocks the doors but the truck will not start

Two separate systems. Remote entry working proves the battery and RF side are alive, and says nothing about the immobilizer authentication.

Smart key only works pressed against the start button

The designed backup for a weak fob. Replace the coin cell first — if that does not restore normal operation, the transmitter is failing and a replacement fob is the fix.

Key worn round, works only sometimes on older models

High-mileage key-slot Toyotas wear both the key and the cylinder. Cutting a fresh key from code, rather than copying the worn one, is the correct fix. Ignition work is covered on our ignition repair page.

Both keys lost between the ramp and the house

The most common version of this call in summer. Keys go into the water, into a cooler, or into a boat cushion, and the spare was never made.

The Honest Boundary

Two things we do not promise blind. First, the newest Toyota builds need a VIN-specific check before we commit to a firm all-keys-lost price — access rules move by model year and we would rather tell you now. Second, if the immobilizer module itself has failed rather than merely lost its key data, that is a different scope of work and may belong at a dealer. A shop that quotes any vehicle, any year, without asking a question is guessing with your money.

After This Is Over: Make the Spare

Every one of these calls has the same root cause, and it is not carelessness. It is that a second key was never made. On a transponder Tundra it is the cheapest line on our price list. On a smart-key Sequoia it is still a small fraction of the emergency version. Make it, and store it somewhere that is not the vehicle and not the same ring as the first.

Frequently Asked Questions

Can a locksmith make a Toyota Tundra key with no original? Yes. We originate the mechanical cut from your VIN and program the new key or smart fob to the vehicle's immobilizer on site. Proof of ownership is required before we start, and no tow to a Toyota dealer is needed.

How much does all-keys-lost cost on a Tundra in Granbury? As of July 2026 in Hood County, transponder all-keys-lost work generally runs $185–$325, and smart-key work $150–$350 depending on the fob required. The exact figure is quoted by VIN before dispatch and does not change on arrival.

Will you come to a boat ramp or a lease road? Yes. Ramps, pasture gates, lease roads, job sites, and roadside are all normal calls. Send a map pin or give us a cross street — rural addressing, not distance, is what makes an arrival late.

How long does it take? Typically 45 to 90 minutes on site for transponder vehicles, plus drive time across the county. Some smart-key procedures take longer.

My smart key only works when I hold it against the start button. Is the truck broken? No — that is the built-in backup for a weak or dead fob battery, and it proves the vehicle side is working. Replace the coin cell first. If normal operation does not return, the fob transmitter is failing.

Does the dealer have to do this because it is a Toyota? No. Independent automotive locksmiths perform Toyota key origination and immobilizer programming routinely, with security data access through the NASTF Vehicle Security Professional program. Only certain very late-model operations remain manufacturer-only, and we check your VIN before quoting.

What if the key was stolen rather than lost? Say so. Many all-keys-lost procedures clear previously paired keys, so a stolen key stops working. That is usually what you want, and it determines which procedure we run.
