The Toyota Tundra is the full-size workhorse, and around Statesboro it earns its keep: contractors load up lumber, haul trailers, and run these trucks hard for years. That heavy use is why our Tundra calls tend to be a spare kept in the toolbox or a lockout at a busy job site where standing around is not an option. A working key for a Tundra is not a single universal part, because the truck moved through four distinct key eras, and the right one depends on which generation you own.
We are a mobile automotive locksmith and come to wherever the truck is, whether that is a supply run parking lot, a driveway off Northside Drive, or a job site out past the edge of town. This guide covers what the Tundra uses in each generation and how a lost-key or remote-head-key job runs.
What Changed Across Tundra Model Years
The earliest 2000-2006 Tundras use a TR47 blade with a 4D67 transponder chip, so the truck has to read that chip before it will crank. The 2007-2013 generation moved to the TOY43 blade with a 4D67 chip, and although both are turn-key trucks, a blank cut for one will not fit the other.
The 2014-2021 trucks could come either way: a true proximity key or a GQ43VT20T remote head key that combines the cut blade and the remote into one unit. The newest 2022-2026 generation went standard proximity on the HYQ14FBB fob. Because the blade, the chip, and in later years the whole fob changed across these eras, matching the key to your specific year and setup is the single most important step.
Tundra Key Systems, Year by Year
The Tundra has run through four key setups, and the right blade, chip, or fob depends entirely on the year. The shape of the key and whether the truck has a start button are the quickest tells, and we confirm the exact part by VIN before we head out to the truck.

Lost-All-Keys Service for the Tundra
Losing every key to a Tundra is a different job from copying a spare, and on a job site it is one we handle on-site so you are not down a truck. With no key to act as an authentication seed, the programmer reads the immobilizer data from the truck before it can enroll a new key, which on the proximity years means working through the security system rather than cloning an existing fob.
It does not require a tow to the dealer for most Tundra years. We build the key from your VIN, cut the blade or pair the proximity fob, enroll it, and confirm the engine starts before we call it done.
What Your Tundra Fob Symptoms Mean
Before assuming the fob has failed, rule out the battery. Tundra fobs run on a CR2032 coin cell, and a weak one is the most common reason a remote stops locking from a distance or a proximity fob makes you hold it against the start button to crank.
A true programming fault is different. If a new battery does not help, if the key turns but the engine will not start, or if a security light stays lit, the trouble is on the immobilizer side and the key needs to be re-paired to the truck, which a battery swap cannot do.
A Spare Tundra Key Is Easier Now Than Later
If you still have one working key, a planned spare is the smart move for a truck you depend on. With a key on hand to act as the authentication seed, programming a second is a short job, and a Tundra running daily hauls on a single key is one lost fob away from a stalled job. We make and program spares on-site.
Push-Button Start and the Tundra Fob
On the 2014-2021 trucks that came with proximity, and standard on the 2022-2026 generation, the Tundra uses a fob with push-to-start. With the fob in your pocket the doors unlock on touch and the truck starts with a button. When the system stops recognizing it, suspect a weak coin cell first and a pairing fault second, and we verify lock, unlock, and push-button start before we leave.
Mechanical Lock and Ignition Help for the Tundra
On the older bladed Tundras, the call is sometimes the ignition rather than the key. The TR47 and TOY43 cylinders wear over years of hard daily use, and the symptom is a key that sticks, has to be worked back and forth, or will not turn even though it is the correct key. That is a mechanical repair, not a programming one, so we diagnose it at the truck; sometimes a fresh key cut to the original code restores smooth operation, and other times the cylinder needs service.
How Tundra Key Problems Tend to Happen
Example. A contractor loading up for a job calls because the only key to a 2010 Tundra went missing somewhere on the site. We build a fresh TOY43 key from the VIN, program the chip on-site, and recommend a toolbox spare so a single key never strands the truck again.
Example. An owner with a 2018 Tundra is not sure whether their truck uses a remote head key or a true proximity fob. Because the 2014-2021 run came both ways, we confirm the setup by VIN before ordering and then program the correct fob on-site so it works the first time.
Example. A driver near the Market District comes out to a 2023 Tundra that will not recognize the fob. A weak CR2032 coin cell is the culprit, the proximity fob comes back with a fresh cell, and we verify push-button start before they get back on the road.
What Helps Us Help Your Tundra Faster
- The year of your Tundra, which narrows down the blade, chip, and fob type immediately.
- The VIN, usually visible through the lower corner of the windshield, so we can confirm the exact part.
- How many working keys you have, since a spare from a working key is a different job than a lost-all-keys.
- Whether the truck has a start button (proximity), a remote head key, or a plain bladed transponder.
- A photo ID and the registration or title, so we can verify the truck is yours before programming a key.
- Whether the trouble is the key, the remote buttons, or the ignition turning, so we bring the right tools.
Where We Help Tundra Drivers Locally
We serve Tundra owners across Statesboro and all of Bulloch County, coming to homes, job sites, and supply runs instead of asking you to bring the truck in. Whether you are parked near the Market District, off Northside Drive, or out on Hwy 80, we usually arrive with the right parts for your year on the first visit.
Should You Call the Dealer or a Locksmith?
The Toyota dealer can make a Tundra key, but for most years it means getting the truck there, waiting for an appointment, and losing your work vehicle while it sits on their schedule. As a mobile locksmith we bring the blanks, chips, and programmer to the truck and do the work in your driveway or on a job site. The one exception we are honest about is the rare case that genuinely needs manufacturer coordination, which we flag when we confirm your VIN.

Questions About Toyota Tundra Keys
Can you make a Toyota Tundra key without the original?
Yes. For the large majority of Tundra years we make a key with none in hand by reading the immobilizer data and building the key from your VIN, then enrolling it against the truck. It takes more steps than copying a spare but does not require a dealer trip for most years.
How do I know which Tundra key I need?
It comes down to the model year. The 2000-2006 trucks use a TR47 bladed transponder, 2007-2013 use a TOY43 bladed transponder, 2014-2021 came as either a remote head key or proximity, and 2022 and newer use a standard proximity fob. We confirm the exact setup by VIN.
Does my 2014-2021 Tundra use a remote head key or a proximity fob?
It can be either. A 2014-2021 Tundra could come with a GQ43VT20T remote head key or a true proximity fob, so we confirm which system your truck uses by VIN before ordering rather than guessing and bringing the wrong part.
My Tundra fob stopped working. Is it broken?
Often not. Tundra fobs use a CR2032 coin cell, and a weak battery is the most common reason a remote stops responding at a distance. If a fresh cell does not fix it and the engine still will not start, the fob likely needs to be re-paired to the truck.
Why is my older Tundra key getting hard to turn?
On higher-mileage bladed Tundras that is usually a worn ignition cylinder rather than a bad key. Years of hard use wear the lock, so the key sticks or will not turn even though it is the right key. We diagnose this at the truck and tell you whether a fresh key or ignition service is the fix.
