Infiniti Q60 Key Replacement

Q60 keys by generation

The second-generation Q60 shares its smart keys with the Q50 of the same years. 2017-2018 coupes use FCC ID KR5S180144204 (part 285E3-4HB0C, four buttons) or a five-button remote-start fob under KR5S180144014 (285E3-4HK0A). From 2020, coupes use KR5TXN7 fobs, four-button 285E3-6HE1A or five-button 285E3-6HE6A. All take a CR2032 and carry a hidden emergency blade. 2019 cars fall between the two families, so check the label on your original. Programming is OBD-II based: the programmer derives the PIN from the body control module, then registers each fob, dropping any that are not present. Spare fobs are routine. With all keys lost the job depends on build date and tool coverage, so we confirm by VIN first; when it is doable we open the coupe, cut the emergency blade by code and register new fobs on site.

The 2014-2015 Q60 coupe and convertible keep the G37's four-button Intelligent Key: lock, unlock, trunk and panic, listed under FCC ID KR55WK48903 with part number 285E3-JK65A, powered by a CR2032. A mechanical emergency key slides out of the fob for the driver's door. There is no turn-key version, and fobs from the 2017-on Q60 will not work on these cars, so the G37-style fob is the correct replacement. We register fobs through the OBD-II port using the BCM's PIN, the same process as on a G37. All fobs you want to keep need to be present, since the system re-learns its list each time. All-keys-lost is done on site with an emergency blade cut by code and new fobs registered in a single visit.

Infiniti key security

Nearly every Infiniti sold in the US since 2000 has an engine immobilizer built on Nissan's NATS (Nissan Anti-Theft System). A transponder in the key or fob has to answer the car's challenge before the engine is allowed to run, and the small security light on the dash blinks while the system is armed. The chip inside changed over the years. The 1997-2001 Q45 used a fixed-code Texas 4C transponder, while the G20, I30, I35 and QX4 used the Texas Crypto 4D60. From 2003 the G35, FX and later models moved to the Philips ID46, which stayed in the Intelligent Key fobs of many models well into the 2010s. Infiniti's Intelligent Key lets the car recognize a fob in your pocket; some early cars such as the FX paired it with a turning ignition knob, and push-button start became standard on most models by about 2009. From roughly 2013 the newer fobs use different electronics, and a replacement has to match both the FCC ID and the IC number printed on the original. The QX30 is the outlier: its key system came from Mercedes-Benz.

Infiniti key programming runs through the OBD-II port under the dash. Most models from 2003 on need a security PIN, which professional programmers read or calculate from the body control module (BCM); older NATS cars use a comparable code from the immobilizer side. Two rules catch owners out. First, registering keys usually wipes every key that is not present, so bring all the keys and fobs you want to keep. Second, the replacement has to match the original's FCC ID and part number, and on newer fobs the IC number as well; a fob that looks identical but was built for another model will not register. Used smart keys from about 2013 on are locked to their first car and must be unlocked before reuse. On the newest platforms, including the 2022-on QX60 and 2025-on QX80, tool coverage varies by build, so we check the VIN before promising an all-keys-lost job.

All Q60 keys lost

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 Q60 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. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
3. Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
4. Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
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.

Dealer or mobile locksmith?

Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Infiniti Q60, ask us directly and you'll get a plain answer.

How the job works

1. Identify the exact key your Q60 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. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
3. Get the key code or decode the lock. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Infiniti keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Infiniti system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
6. Test everything and clear out old keys. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.

What affects the price of a Q60 key

• The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your Q60 came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• 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.

Q60 key types explained

• Smart proximity key (push-to-start). Making a new smart key is mostly a programming job. The fob has to match the vehicle's FCC ID, frequency and chip, and then the keyless system must be told to accept it, normally through the OBD-II port. Depending on the platform, that can mean entering a PIN, waiting through a timed security procedure, or on some newer vehicles, using manufacturer online access. When every key is lost, certain models need a module removed and read on the bench. For your Infiniti Q60 CV37 (2nd generation), we'll tell you which of those applies, and if a step is dealer-only, you'll hear it before we drive out. The emergency blade hidden inside the fob is cut by code during the same visit.

Why a spare key pays for itself

• A spare stored safely at home rescues you from a locked car with the fob sitting on the seat, a key dropped somewhere along a hiking trail, or a fob that stops responding on a busy morning. Keep it indoors, never in a magnetic box under the bumper.
• 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.

Tips from a mobile locksmith

• Photograph the back of your fob and any key tag that came with the car. The FCC ID, part number and key code printed there make ordering a replacement faster and more accurate. Store the photos somewhere you can reach from any device, not only on the phone that might go missing along with the keys.
• Never hide a spare key or fob on the outside of the car. Magnetic boxes in wheel wells and under bumpers are the first places a thief checks, and with a proximity fob, a hidden key can let anyone open the doors and drive away. Keep the spare at home or with someone you trust.
• Southern California heat is hard on keys. Fob batteries drain faster, plastic housings turn brittle, and rubber button pads crack when a key spends summer afternoons on a dashboard or in a sunny cup holder. Carry the fob with you or keep it shaded, and replace batteries before summer rather than after they fail.
• Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.

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.
• Some late-2000s push-button Infinitis can show a steering-lock fault that looks like a key problem: the car refuses to start and the dash flags the steering lock. That points to a column-module repair, not a new fob.
• 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.
• On older turn-key models like the I35, G35 and QX4, worn keys and ignition wafers cause sticking or no-turn ignitions. Cutting a fresh key by code, rather than copying a worn one, often solves it.
• Intelligent Key shells crack and emergency-key releases break with age. A replacement shell can reuse the original circuit board, so the fob usually stays registered to the car and does not need a full new key.
• 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.
• A dead 12-volt battery can leave you outside a push-button Infiniti even with a good fob. The mechanical key hidden inside the fob opens the driver's door so you can reach the hood release.

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.
