2015 Infiniti QX60 Key Replacement

2015 QX60 key specs

QX60 fobs changed by build date. 2014-2016 models use the JX35-style fob, FCC ID KR5S180144014 (IC 014), in four-button (285E3-9NB4A) or remote-start five-button (285E3-9NB5A) form; a three-button 285E3-9NB3A is also listed for 2014-2018. 2016-2018 models use a fob under the same FCC ID with a different IC (204), part 285E3-9NF4A or 9NF5A, and 2019-2020 models moved to KR5TXN7 fobs (285E3-9NR4A or 9NR5B). All use a CR2032 and hide an emergency key.

What's specific to the 2015 QX60

The 2015 Infiniti QX60 is the second of 7 model years in the QX60 L50 (1st generation) (2014–2020), so it shares its key system with the rest of that run, which makes replacement parts easy to source. At roughly 11 years old, a 2015 Infiniti QX60 has usually seen real wear. Fob cases crack, buttons wear through and solder joints loosen at this age, so a new shell or a replacement remote often beats repairing the old one. Many have changed hands more than once, so erasing keys you can't account for is worth doing during the visit.

Smart-key cars like the 2015 QX60 can be targeted with relay attacks that extend the fob's signal from inside your home, so keep fobs away from exterior walls or in a signal-blocking pouch, and have any missing fob erased from the car.

Key options for the 2015 Infiniti QX60

• Smart proximity key (push-to-start). Proximity keys bring a security trade-off worth understanding. Because the fob is always listening, thieves with relay equipment can stretch its signal from inside your house to the car in the driveway. Keeping the fob away from exterior walls, or in a signal-blocking pouch, closes that gap, and some fobs offer a sleep mode described in the owner's manual. If a smart key for your 2015 Infiniti QX60 is lost or stolen, programming a replacement is the moment to delete the missing fob from the car's memory. And be wary of used fobs from online sellers: a lot of them are locked to the vehicle they came from and can't be reprogrammed to yours.

How the Infiniti immobilizer works on the QX60

• Catalogs list the same FCC ID, KR5S180144014, for 2014-2016 and 2016-2018 fobs, but the IC numbers differ (014 versus 204), so both identifiers must match.
• Catalogs list the same 285E3-9NB4A fob for gasoline and hybrid 2015-2016 QX60s.
• The 2014 QX60 is the 2013 JX35 renamed, and their early fobs are interchangeable.

Programming a 2015 QX60 key

We register QX60 fobs through the OBD-II port after the programmer retrieves the PIN from the body control module; fobs not presented are erased. The key step is supplying the right fob for your build date, which we confirm from the VIN and your original's label. All-keys-lost depends on build date and tool coverage; when it is doable we cut the emergency blade by code and register new fobs on site.

Spare fobs are routine; all-keys-lost on these encrypted-fob builds can need extra steps or a dealer PIN, which we confirm by VIN before quoting.

Lost every key to your QX60?

Losing every key to an Infiniti is often fixable on site without a tow, depending on the model. We verify ownership first, with your ID plus the registration or title, and then open the car without damage. The mechanical blade is cut by key code or decoded from a door lock; most Infinitis from 2000 into the 2020s use the same NSN14-style edge-cut profile (Ilco DA34), with a few older exceptions. On turn-key models that blade gets a transponder head and is programmed over OBD-II. On Intelligent Key models we register new fobs to the car and cut the emergency blade that hides inside each one. Several models are marked limited here because all-keys-lost can need extra procedures or a dealer PIN, and the QX30's Mercedes-based system is a dealer job. We tell you which case applies before any work starts.

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Infiniti QX60 can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. Entry comes before key-making because we need access to the ignition, the OBD-II port and sometimes the documents in the glove box. We take care with weather stripping, door frames and paint, and we confirm the dash VIN matches your registration before going any further.
3. Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
4. Program the key to the immobilizer. All-keys-lost programming often takes longer than adding a key, because the car has no trusted key to authorize the change. We follow the procedure your Infiniti QX60 requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
5. Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.

Why a spare key pays for itself

• A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.
• Two drivers sharing one key is a daily negotiation. A second key lets a partner, teenager or coworker use the vehicle without handing keys back and forth in parking lots, and it means one person losing their key ring doesn't leave the whole household stuck.
• Some vehicles make it hard to add a key once you're down to one. Certain immobilizer systems let an owner program an extra key on-board only when two working keys are present, so a second key preserves the easy options for later and avoids a full reset.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2015 Infiniti QX60 we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

QX60 key battery

If a new CR2032 doesn't bring the fob back, the battery wasn't the problem. Common culprits include a battery holder whose solder joints have cracked from drops, contacts corroded by moisture, worn rubber button pads that no longer reach the circuit, or a board damaged by water. We can test whether the fob is transmitting at all and inspect the board closely. Sometimes a new shell or a resoldered holder solves it; sometimes the fob has to be replaced and programmed. Meanwhile, the car can usually still be started with the fob held at the backup spot described in the owner's manual.

How the job works

1. Identify the exact key your QX60 uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
2. Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
3. Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
4. Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your QX60, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of a QX60 key

• The type of key. The biggest factor is technology. A plain mechanical key is a cutting job only. A transponder key adds a chip and programming. Remote-head and flip keys add a circuit board, and a proximity fob for a push-button Infiniti QX60 is the most involved of all, both in the part itself and in the programming.
• All keys lost or adding a key. On some vehicles, losing the last key changes the programming entirely, from a quick add-key procedure to a full immobilizer reset or a module read on the bench. That extra labor shows up in the price, and it's the strongest argument for keeping a spare in the house.
• Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Infiniti system adds equipment time and labor to the job.
• Blade style and cutting. Traditional edge-cut blades are quick to cut. High-security laser-cut blades, with a groove milled into the side, need a specialized machine and more care, and the blanks themselves cost more. If we have to decode a lock to find the cuts, that adds labor as well.

Common Infiniti key problems

• Weak fob batteries are the most common cause of a key-not-detected warning on push-button Infinitis. Most fobs take a CR2032 or CR2025 coin cell, and a fresh battery often clears the warning without any reprogramming.
• A flashing security light with a key that looks fine usually points to a cracked transponder, a fob with a damaged chip, or an aftermarket remote-start bypass module interfering with the immobilizer.
• Programming wipes keys that are not present. Owners who add a spare without bringing every other key often find an old fob suddenly stops starting the car, so gather every key before the appointment.
• Secondhand fobs bought online often fail. Newer smart keys lock to their first vehicle and must be unlocked, and a fob with the wrong FCC ID, IC number or part number will not register no matter how similar it looks.

Tips from a mobile locksmith

• When a key's head cracks or its blade bends, replace it before it fails. A transponder chip can slip out of a split head, and a bent blade can break off inside the ignition or door lock, turning a simple key replacement into an extraction and repair job. Small symptoms are the inexpensive time to act.
• On any vehicle with a turn-key ignition, keep the key ring light. A heavy cluster of keys, tools and charms swings with every bump and slowly wears the ignition wafers and the key itself. When the key starts to stick or needs a wiggle to turn, deal with it early, before it stops turning entirely.
• Every so often, use the mechanical blade in the driver's door lock. Cylinders that go years without a key can seize from dust and dried grease, and you won't find out until the day the fob dies and the blade is your only way in. A small shot of dry lubricant keeps the lock ready.

Proof of ownership

Not every situation fits the simple case, so here's how we handle the common exceptions. For a leased or financed vehicle, a registration that lists you as the registered owner or lessee works with your ID. If you just bought the car, bring the signed title or bill of sale along with your ID. For a company or fleet vehicle, we need written authorization from the business plus the driver's ID. If the car belongs to a family member, the registered owner should be present or provide signed permission and a copy of their ID. Rental vehicles go through the rental company.
