The Infiniti QX80 traces its lineage back to the QX56, and that rename came with a change in the Intelligent Key, which is the detail that catches owners ordering a replacement. A key built for the earlier QX56 will not be accepted by a later QX80, and the reverse is also true, so the badge on the tailgate is not enough to identify the right fob. With this big luxury hauler, the fob designation is what we confirm first.
We are a mobile automotive locksmith and bring the work to wherever the QX80 is parked, whether that is an upscale driveway in Bulloch County, a lot at Statesboro Crossing, or a space off Brampton Avenue. This guide covers what the QX80 uses in each era, how a lost-key visit runs, why a replacement has to restore every convenience, and how to tell a dead fob battery from a real programming fault.
Infiniti QX80 Key Types by Model Year
The QX80 has used Intelligent Keys on the NSN14 emergency blade across its run, but the exact fob changed with the QX56-to-QX80 rename, so the right one depends on your year. We confirm the fob by VIN before we head out so the new key restores every convenience, not just start.
NSN14 emergency blade. FCC: CWTWB1U787 / S180144014.
NSN14 emergency blade. FCC: CWTWB1G744 (shared Y62 platform key, PN 285E3-1LB5A).
How QX80 Key Systems Changed Over the Years
The 2011-2013 trucks, badged QX56, use the NSN14 emergency blade with the CWTWB1U787 or S180144014 Intelligent Key. These are big luxury haulers where remote start and memory recall are tied to the fob, so a replacement has to bring those back.
From 2014-2025 the QX80 moves to the CWTWB1G744 fob, a shared Y62 platform key (PN 285E3-1LB5A), still on the NSN14 blade. Because the fob FCC changed with the rename, ordering a QX56 key for a later QX80 gets a remote the truck will not accept, which is why matching the exact fob to your year is the first step before any programming.
QX80 Fob: Battery Problem or Programming Problem?
Before assuming the worst, rule out the battery. The QX80 Intelligent Key runs on a CR2032 coin cell, and a weak one is the most common reason the remote stops responding from a distance or the truck makes you hold the fob to the start button. A fresh cell often brings it back.
A real programming fault is different. If a new battery does not help, if the button presses but the engine will not start, or if a key or security light stays lit, the issue is on the immobilizer side and the key needs to be re-paired. A counter battery swap cannot do that.
Push-to-Start and Proximity Keys on the QX80
The QX80 uses an Intelligent Key with push-to-start: with the fob in a pocket or bag, the doors unlock on touch and the truck starts from the button. When it stops recognizing the fob, a weak coin cell is the first suspect and a pairing fault the second. Adding or replacing an Intelligent Key is a programming job, and we verify lock, unlock, remote start, memory, and push-button start all respond before we leave.
Lost All Keys to Your QX80?
Losing every working fob on a QX80 is a more involved visit than copying a spare, but one we handle on-site. With nothing to seed authentication, the programmer reads the immobilizer data from the truck and enrolls a new Intelligent Key through the security system. We build the key from your VIN, cut the NSN14 emergency blade so the door backup works, pair the fob, and confirm both the engine and the convenience features before we close out.
On a luxury hauler this loaded, it pays to match the exact fob from the start so remote start and memory recall come back with it rather than as a separate problem later.
Why a Spare QX80 Key Is Worth It
If you still have one working fob, a planned spare is easy insurance on a truck this size. With a key on hand to seed the process, programming a second Intelligent Key is short and straightforward, and a big luxury SUV running on a single fob is one drained coin cell away from a much harder day. We make and pair spares on-site, so there is no waiting on a dealer's calendar.
QX80 Ignition and Door Lock Issues
Since the QX80 starts from a button, there is no turn-key ignition cylinder to wear, but the NSN14 emergency blade and the driver door lock still deserve attention. That blade is your way in when the fob battery dies, and a lock that has rarely been used can feel stiff the first time. We make sure the emergency blade is cut correctly and turns the door cleanly so your backup is ready when it counts.
What to Have Ready for Your QX80
- The model year of your QX80, including whether it is an early QX56-badged truck, since the fob differs.
- The VIN, visible through the lower windshield, so we can match the exact fob.
- How many working fobs you have, since a spare is a shorter job than an all-keys-lost visit.
- Which features matter most, such as remote start or memory, so we confirm they return.
- A photo ID and the registration or title, so we can verify the vehicle is yours before programming.
- Whether the trouble is the fob, the remote functions, or a locked door, so we bring the right tools.
Dealer vs Mobile Locksmith for the QX80
An Infiniti dealer can make a QX80 key, but it usually means getting the truck to the dealership, waiting on an appointment, and leaving a big SUV on their schedule. As a mobile locksmith we bring the blanks, the programmer, and the correct Intelligent Key to you and finish the job in your driveway or a lot. If a particular case genuinely needs manufacturer coordination, we flag it when we confirm your VIN instead of after we arrive.
QX80 Key Service Around Statesboro
We serve QX80 owners across Statesboro and all of Bulloch County, coming to homes, workplaces, and lots rather than asking you to come to us. Whether the truck sits in an upscale Bulloch County neighborhood, off Fair Road, along Northside Drive, or out toward US-301, we bring the service to the vehicle and aim to arrive with the right fob for your VIN the first time.
Example QX80 Situations We See
Example. An owner in an upscale Bulloch County neighborhood found the only fob to a 2017 QX80 would not start the truck after a road trip. A weak CR2032 coin cell was the cause; we replaced it, confirmed remote start and memory came back, and made a spare for the household.
Example. A driver at Statesboro Crossing ordered a fob online for a 2015 QX80 that was actually a QX56 key the truck would not accept. We matched the correct CWTWB1G744 fob by VIN, paired it on-site, and verified every convenience returned.
Example. A QX80 along Northside Drive lost both fobs. With nothing to seed from, we read the immobilizer data, built the NSN14-bladed Intelligent Key from the VIN, enrolled it, and tested start and the door backup before leaving.

Infiniti QX80 Key Questions, Answered
Can you make an Infiniti QX80 key with no working fob?
Yes. When every fob is gone we read the immobilizer data, build the Intelligent Key from your VIN, and enroll it against the truck. It is more involved than copying a spare, but for the QX80 it does not require a dealer visit in most cases.
I bought a fob and the truck will not accept it. Why?
Most often because of the QX56-to-QX80 rename. The fob FCC changed with it, so a QX56 key will not work on a later QX80, and the reverse is also true. We match the correct fob to your VIN so the truck accepts it.
Will a replacement fob bring back remote start and memory?
It should, which is why we match the exact fob to your VIN. The QX80 Intelligent Key carries remote start and memory recall, so a properly paired replacement restores those rather than only starting the engine.
My QX80 fob quit working. Is it the fob or the truck?
Start with the battery. The Intelligent Key uses a CR2032 coin cell, and a weak one is the usual reason it stops responding from a distance. If a fresh cell does not help and a key warning stays lit, the fob likely needs to be re-paired.
What if the fob battery is dead and I am locked out?
The NSN14 emergency blade inside the Intelligent Key opens the driver door even with a flat battery. If you have lost that ability, we can cut the blade by VIN on-site, get you inside, and address the fob once you have access.
Do you come to me in the Statesboro area?
