The Toyota 4Runner stayed transponder-based longer than most vehicles its age, which is part of why it earns such loyalty out here. These trucks haul to deer leases and trailheads all over the region, and they keep running well past the point where other SUVs have moved on, so the keys we replace span a wide stretch of years. The first job on any 4Runner call is figuring out which generation we are dealing with before we cut a blade or pair a fob.
We are a mobile automotive locksmith and come to wherever the 4Runner is, whether that is a driveway in town or a gravel lot at a hunting camp. The typical 4Runner call is a spare cut before hunting season or a lockout out at the lease, and both go faster when we already know your year.
What Changed Across 4Runner Model Years
Early 4Runners in the 2003-2009 run use a TOY43 blade with a 4D67 transponder chip in the head, a rugged turn-key setup. The 2010-2013 trucks kept the TOY43 blade but switched the transponder to the 4D68 chip, so two trucks that look almost identical at the key need different chips inside.
From 2014-2026 the 4Runner added a proximity option or a GQ43VT20T remote head key with push-to-start available. Because the chip changed mid-blade and the later trucks introduced a smart system, matching the key to your specific year is the single step that keeps the job from stalling.
4Runner Key Systems, Year by Year
The 4Runner leaned on bladed transponders for years before adding a proximity option, so the right blade, chip, and programmer depend on your model year. The quickest tell is whether you turn a key in a cylinder or press a start button, and we can confirm the exact part by VIN before we load up.

Lost-All-Keys Service for the 4Runner
Losing every working key to a 4Runner is a different job from copying a spare, but one we handle in the field regularly. 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 smart-equipped years means working through the vehicle's security system rather than cloning an existing fob.
It takes more steps than a spare but does not require a dealer tow for the large majority of 4Runner years. We build the key from your VIN, cut the TOY43 blade or pair the proximity fob, enroll it, and confirm the engine starts before we head out.
What Your 4Runner Fob Symptoms Mean
Before assuming the worst, rule out the battery. A 4Runner remote or smart fob runs on a coin cell, and a weak one is the most common reason the remote stops locking from a distance or the smart fob makes you hold it close to start. A fresh cell often brings it right back.
A real programming fault is different. If a new battery changes nothing, if the key turns but the engine will not catch, 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 parts-counter battery swap cannot do.
A Spare 4Runner Key Is Easier Now Than Later
If you still have one working key, a planned spare made before hunting season is the smartest move with a 4Runner. With a working key on hand to seed the programming, adding a second is a short job, and a truck that lives out at the lease or trailhead is the last place you want to be down to a single key. We cut and program spares on-site, so there is no dealer appointment to plan around.
Push-Button Start and the 4Runner Fob
From the 2014 trucks onward, the 4Runner offers a proximity option with push-to-start alongside the GQ43VT20T remote head key. As long as the fob is in your pocket or pack, the doors unlock on touch and the engine starts with a button. When the system stops recognizing it, suspect a weak coin cell first and a pairing fault second. Adding or replacing a proximity fob is a programming job, and we verify lock, unlock, rear gate, and push-button start before we leave.
Mechanical Lock and Ignition Help for the 4Runner
On higher-mileage 4Runners, the call is often about the ignition rather than the key. The TOY43 bladed trucks wear their cylinders over years of hard use, and the symptom is a key that sticks, has to be wiggled, or will not turn at all even though it is the right 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 turning, and other times the cylinder needs service.
How 4Runner Key Problems Tend to Happen
Example. A hunter heading out from a lease off Hwy 67 realizes the only key to a 2008 4Runner is missing before opening weekend. We cut a fresh TOY43 blade, program the 4D67 chip on-site, and add a spare so the truck is never down to one key at the camp.
Example. An owner with a 2012 4Runner needs a second key but is not sure which chip it takes. We confirm the truck uses the 4D68 on the same TOY43 blade, then cut and program the spare correctly the first time.
Example. A driver near US-301 locks the smart fob inside a newer 4Runner loaded with gear. We get them back in, then check the proximity fob and confirm push-button start before they roll out.
What Helps Us Help Your 4Runner Faster
- The year of your 4Runner, which narrows 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 lost-all-keys.
- Whether the truck has a start button or a key you physically turn in the ignition.
- A photo ID and the registration or title, so we can verify the vehicle is yours before programming.
- Whether the trouble is the key, the remote buttons, or the ignition turning, so we bring the right tools.
Where We Help 4Runner Drivers Locally
We serve 4Runner drivers across Statesboro and all of Bulloch County, coming to homes, job sites, and gravel lots. Whether the truck is off US-301, out along Hwy 67, near Veterans Memorial Parkway, or down a side road toward a lease, we bring the service to the vehicle and usually arrive with the right parts for your year on the first trip.
Should You Call the Dealer or a Locksmith?
The Toyota dealer can make a 4Runner key, but for most years that means getting the truck to the dealership and going without it while it sits on their schedule, rough when it is your work and weekend rig. As a mobile locksmith we bring the blanks, chips, and programmer to your driveway or the camp. The rare exception that needs manufacturer coordination is something we flag when we confirm your VIN.

Questions About Toyota 4Runner Keys
Can you make a Toyota 4Runner key with none in hand?
Yes. For the large majority of 4Runner years we make a key with none in hand by reading the immobilizer data and building the key from your VIN, then enrolling it to 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 4Runner key I need?
It comes down to the model year. The 2003-2009 trucks use a TOY43 bladed transponder with a 4D67 chip, 2010-2013 use the same blade with a 4D68 chip, and 2014 and newer offer a proximity option or a GQ43VT20T remote head key. Whether the truck has a start button is the quickest tell, and we confirm the part by VIN.
My 4Runner keys look the same. Are the chips the same too?
Not always. The TOY43 blade carried over, but 4Runners switched from the 4D67 to the 4D68 chip around 2010, so the right transponder depends on the year even when the blade looks identical. We match the chip to your specific truck before programming.
My 4Runner fob stopped working. Is it broken?
Often not. The fob runs on a coin cell, and a weak battery is the most common reason it stops responding at a distance or makes you hold it close to start. 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 4Runner key getting hard to turn?
On higher-mileage 4Runners that is usually a worn ignition cylinder rather than a bad key. Years of hard use wear the lock, so the TOY43 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.
