One working Infiniti key and need a backup?

Infiniti Key Programming
Canadian Locksmiths writes the new key transponder data to the Infiniti NATS immobilizer through the OBDII port using authorized Infiniti CONSULT dealer software. NATS5 vehicles (2003–2007 G35, FX35) use 4D60 chips; NATS6 models (2008–2019 G37, Q50, QX60, QX80) use ID46 PCF7936 chips; NATS7 vehicles (2020+ QX60, QX55, QX50) require 4A HITAG-AES 128-bit encryption that only factory-level software can program.

Infiniti Key Extraction
Broken Infiniti key blade stuck in the ignition or door lock? Canadian Locksmiths removes the broken NSN14 fragment with non-destructive hook tools and screw extractors sized for the ignition housing, then cuts a fresh NSN14 blade on-site.

Every Infiniti key blade Canadian Locksmiths cuts is precision-machined on a high-security key cutting machine. NSN14 is the standard blade profile for all Infiniti models from 2003 to present, including the Intelligent Key fob insert blade. The technician decodes the lock cylinder or uses VIN-based cutting data to produce a factory-specification NSN14 blade for the ignition and door locks.

Infiniti Key Replacement Pricing in Windsor
Infiniti key replacement pricing in Windsor depends on the model year, NATS immobilizer generation, and whether you have a working key or need all-keys-lost recovery. The table below covers mobile service, NSN14 blade cutting, and transponder or Intelligent Key programming with a 90-day materials warranty.
Infiniti key replacement in Windsor spans several NATS immobilizer generations. Spare NSN14 transponder keys with an ID46 PCF7936 chip cover the G35, G37, FX35, and older models. Remote-head keys with the KR55WK48903 fob fit the G35 and G37 (2003–2013), including blade cutting and remote programming. Spare Intelligent Key fobs use KR5S180144203 for the Q50, Q60, and QX50 (2014–2019) with NATS6 programming, and KR5TXN7 for the QX60 and QX55 (2020+) with NATS7 HITAG-AES programming. All-keys-lost Intelligent Key recovery uses a BCM reflash and the CWTWB1G744 fob on the QX80. Every job is mobile at your Windsor location with no towing required.
Prices may vary by model year, NATS immobilizer generation, key type, and whether a working key is present. All-keys-lost recovery requires NATS BCM reflash and costs more than spare key programming. For a precise quote with your Infiniti’s year, model, and key situation: call or text 519-979-1270
How Infiniti Key Replacement Works in Windsor
Most Infiniti key replacements take 30 to 60 minutes on-site. The bonded, certified, and insured mobile technician brings the key programming system, authorized Infiniti CONSULT dealer software, NSN14 blade blanks, and Infiniti Intelligent Key fobs to your Windsor-area location, with no towing or dealer appointment.
Infiniti key replacement typically takes 30–60 minutes on-site. The mobile BONDED, CERTIFIED & INSURED Infiniti key specialist handles cutting, programming, and testing before the technician leaves. Infiniti vehicles use NATS (Anti-Theft System) immobilizer security across three generations: NATS5 on 2003–2007 models with 4D60 transponder chips, NATS6 on 2008–2019 models with ID46 PCF7936 chips, and NATS7 on 2020+ models with 4A HITAG-AES 128-bit encryption. Each generation requires specific diagnostic protocols and authorized dealer software to program correctly. Canadian Locksmiths carries the complete NATS programming platform for every Infiniti generation.
Infiniti Year and Model
Contact Canadian Locksmiths with your Infiniti year, model, trim, and whether it is a push-to-start Intelligent Key or NSN14 transponder key ignition. The team confirms which NATS diagnostic protocol your model requires.
Run Infiniti Dealer-Grade Diagnostics
The mobile technician connects the diagnostic platform to your Infiniti’s OBDII port and runs authorized Infiniti CONSULT dealer-level diagnostics. This reads the NATS immobilizer status, identifies which transponder protocol your vehicle uses (4D60 for NATS5, ID46 PCF7936 for NATS6, or 4A HITAG-AES for NATS7), checks how many keys are currently registered to the BCM, and verifies the vehicle’s security module is ready to accept new key programming. For all-keys-lost situations, the NATS BCM reflash procedure is initiated at this step to clear previous key registrations and prepare for new fob enrollment.
Cut the Infiniti Blade
The mobile technician cuts your new NSN14 insert blade on-site at your Windsor location using VIN decode data or lock reading from your Infiniti ignition cylinder. Every Infiniti from the 2003 G35 through the 2026 QX60 uses the NSN14 blade profile, cut on the high-security precision key cutting mobile machine to factory tolerances.
Program & Register Infiniti Key
Using authorized Infiniti CONSULT dealer software, Canadian Locksmiths programs the HITAG-AES transponder chip or ID46 clone directly through the OBDII port. The software writes the new key’s unique cryptographic signature to your Infiniti’s BCM, establishing the NATS security handshake required for engine start authorization. For Intelligent Key fobs, the software also registers the wireless signal for keyless entry, push-button start, and trunk release. 2020+ NATS7 vehicles with 128-bit AES encryption require factory-level software access that most aftermarket tools cannot provide – Our team carries the authorized platform on every mobile call.
Test All Infiniti Functions
Verify all Infiniti functions before leaving your Windsor location: remote lock/unlock at 30+ feet, Intelligent Key proximity detection at all four doors and trunk, push-button engine start, NATS immobilizer handshake confirmation via the diagnostic platform status readout, and NSN14 insert blade operation in ignition and driver door lock.
All Infiniti keys are fully tested on-site before the technician leaves. The 90-day warranty covers any defect in the Intelligent Key fob, NSN14 blade, or transponder chip supplied and programmed. If anything fails within 90 days, the technician returns and replaces it at no charge.

Infiniti Car Key Replacement FAQs – Windsor
Windsor Infiniti owners ask these questions every week – about Intelligent Key fob pricing, NATS immobilizer programming, the difference between NATS5, NATS6, and NATS7 security generations, and how the mobile service compares to the dealer visit to Infiniti of Windsor.
Why does my 2020+ Infiniti Intelligent Key cost more to replace than older models?+
Starting in 2019, Infiniti moved from ID46 chips to 128-bit AES encryption (HITAG-AES / 4A chip), expanding across the lineup by 2020. The 2020+ QX60, QX55, and QX50 with FCC ID KR5TXN7 need authorized Infiniti CONSULT dealer software to program, because standard aftermarket tools cannot write the NATS7 128-bit key. Canadian Locksmiths runs the same dealer software platform on-site at your Windsor location with factory-level NATS7 security. Older Infiniti models (2008–2019) use NATS6 with ID46 PCF7936 chips programmed through the OBDII port; pre-2008 models use NATS5 with 4D60 transponders. Every Infiniti key replacement includes NSN14 blade cutting, NATS programming, and a 90-day materials warranty.
Can you make a key for my Infiniti G37 or G35 without the original?+
Yes. The Infiniti G35 (2003–2008) and G37 (2008–2013) use the KR55WK48903 Intelligent Key with a PCF7952A ID46 chip for push-button start and keyless entry. Even with all keys lost, Canadian Locksmiths performs a full NATS6 immobilizer recovery through the OBDII port at your Windsor location. The procedure resets the BCM security module, erases every previously registered key code so lost fobs cannot start the car, programs a new KR55WK48903 fob with a fresh PCF7952A ID46 signature, and cuts a precision NSN14 blade from VIN-decoded data on the high-security key cutting machine. The on-site Infiniti key replacement takes 45–60 minutes with no towing required.
My QX80’s Intelligent Key works intermittently – the push-to-start sometimes doesn’t respond. What’s wrong?+
The Infiniti QX80 (2013–2024) uses the CWTWB1G744 or KR5S180144203 Intelligent Key depending on model year, with a CR2025 battery powering the proximity signal. Intermittent push-to-start most often points to a weak CR2025, so a battery swap frequently resolves it. Canadian Locksmiths diagnoses the root cause on-site through the QX80 OBDII port, reading NATS immobilizer status, fob signal strength, and how many keys are registered to the BCM. If the housing is cracked or the circuit board is water-damaged, the technician supplies and programs a replacement CWTWB1G744 fob using authorized Infiniti CONSULT dealer software and cuts a fresh NSN14 blade on the high-security key cutting machine.
Is the Infiniti Intelligent Key the same system as Nissan’s?+
Yes. Infiniti is the luxury division of Nissan, and both share the NATS (Nissan Anti-Theft System) immobilizer platform across three generations: NATS5 (2003–2007, 4D60 chip), NATS6 (2008–2019, ID46 PCF7936 chip), and NATS7 (2020+, 4A HITAG-AES 128-bit encryption). The BCM protocol, transponder handshake, and key registration procedure are functionally identical between Infiniti and Nissan. Canadian Locksmiths uses the same diagnostic hardware and authorized Infiniti CONSULT dealer software for both brands at your Windsor location. The main differences are the FCC IDs, such as Infiniti KR5TXN7, KR5S180144203, and CWTWB1G744, and the shared NSN14 blade profile carried across both Infiniti and Nissan platforms.
What information do you need to start my Infiniti key replacement?+
Canadian Locksmiths needs the Infiniti year, model, and trim to identify the correct NATS immobilizer generation and FCC ID. Push-to-start Intelligent Key vehicles (QX60 KR5TXN7, Q50 KR5S180144203, QX80 CWTWB1G744, G37 KR55WK48903) require proximity fob programming through authorized Infiniti CONSULT dealer software. Metal-key ignition vehicles use NSN14 transponder blanks with embedded 4D60 or ID46 PCF7936 chips. Tell the technician whether all keys are lost or a working key is present, since all-keys-lost recovery adds a NATS BCM reflash and about 15 minutes over spare programming. Having the VIN ready speeds the NSN14 blade cutting. Call or text (519) 979-1270 for an Infiniti key replacement quote at your Windsor location.
Do I need to tow my Infiniti to the dealership if I lost my car keys?+
No. Canadian Locksmiths provides complete all-keys-lost Infiniti key recovery for every model from 2003 to 2026 at your Windsor location, with no towing required. The technician connects to the Infiniti OBDII port and performs a full NATS immobilizer BCM reflash using authorized Infiniti CONSULT dealer software. The procedure erases all previously registered key codes from the BCM, programs the new Intelligent Key fob (KR5TXN7, KR5S180144203, CWTWB1G744, or KR55WK48903 depending on model), and cuts a fresh NSN14 blade from VIN-decoded data on the high-security key cutting machine. Because the mobile service comes to you, there is no dealer visit and no tow fee.
How long does Infiniti key replacement take on-site?+
Most Infiniti key replacements in Windsor finish in 30–60 minutes after the technician arrives with the key programming system and authorized Infiniti CONSULT dealer software. Spare Intelligent Key programming with a working key present usually takes 15–25 minutes: connect to the OBDII port, register the new KR5TXN7, KR5S180144203, or CWTWB1G744 fob to the BCM, cut the NSN14 blade, and test every function. All-keys-lost recovery with a NATS immobilizer BCM reflash runs about 45–60 minutes because of the extra security reset, and NATS7 vehicles with 128-bit HITAG-AES encryption need the longest cycle. Canadian Locksmiths dispatches Monday to Friday, 9am to 5pm across Windsor and Essex County.
Can you program an aftermarket Infiniti Intelligent Key fob or does it have to be OEM?+
Canadian Locksmiths uses high-quality aftermarket Intelligent Key fobs that meet OEM specifications for transponder chip type (4A HITAG-AES for 2020+ NATS7, ID46 PCF7936 for 2008–2019 NATS6, 4D60 for older NATS5 models), button layout, and NSN14 blade slot compatibility. These fobs are programmed with the same authorized Infiniti CONSULT dealer software the dealer uses, so the Infiniti NATS immobilizer cannot distinguish an aftermarket fob from an OEM fob once the transponder signature is written to the BCM through the OBDII port. The only visible difference is the Infiniti logo embossing on the housing. Every fob supplied and programmed by Canadian Locksmiths carries a 90-day materials warranty.
What Infiniti models do you service for key replacement in Windsor?+
Canadian Locksmiths services Infiniti models from 2003 to 2026 in Windsor and Essex County. SUVs and crossovers: QX80, QX60, QX55, QX50. Sedans: Q50, Q60, Q70.

Each generation uses a specific NATS immobilizer and FCC ID: the FCC ID table in the key types section lists each generation, from KR5TXN7 and KR5S180144203 through CWTWB1G744, CWTWB1U787, and KR55WK49622 for the first-generation QX50. The mobile unit stocks Intelligent Key fobs and NSN14 blanks, programmed on-site with authorized Infiniti CONSULT dealer software.
How much does Canadian Locksmiths save over Infiniti of Windsor for Infiniti key replacement?+
Windsor Infiniti owners typically save up to 50% on Infiniti key replacement by choosing Canadian Locksmiths over Infiniti of Windsor, the nearest Infiniti dealer at 9760 Tecumseh Rd E. The dealer route means ordering the KR5TXN7, CWTWB1G744, or KR55WK48903 fob with a 7–10 business day parts wait, a trip to Tecumseh Road, and, for all-keys-lost jobs, a tow. Canadian Locksmiths programs the Infiniti Intelligent Key at your Windsor location in a single visit using identical Infiniti CONSULT dealer software, so there is no parts wait, no dealer trip, and no tow fee. See the pricing table on this page for current figures.
Why Windsor Infiniti Owners Choose Canadian Locksmiths Over the Dealer
Windsor Infiniti drivers can save up to 50% on key replacement with the mobile service compared to Infiniti of Windsor – the nearest dealer, on Tecumseh Rd E.

Infiniti Key Types Keys Replaced in Windsor
Canadian Locksmiths replaces and programs Infiniti key types at your location: Intelligent Key proximity fobs, remote-head keys, standard transponder keys, and NSN14 blades. Each type uses a different NATS immobilizer protocol, FCC ID, transponder chip, and programming procedure across Windsor and Essex County.
Infiniti Transponder Keys (2003–2013)
Infiniti keys with embedded ID46 (PCF7936) or 4D60 transponder chips are the traditional metal-key style on older models. The G35 (2003–2008), FX35 (2003–2012), FX45 (2003–2008), EX35 (2008–2012), and M35/M37/M56 (2006–2013) use NSN14 transponder blanks with the chip in the key head. NATS5 vehicles (2003–2007) use the 4D60 chip programmed via pin-code extraction, while NATS6 vehicles (2008–2013) use the ID46 PCF7936 chip with rolling-code encryption. Canadian Locksmiths programs both transponder types on-site through the OBDII port using authorized Infiniti CONSULT dealer software.

Infiniti Remote Head & Flip Keys (2003–2013)
Infiniti keys with built-in remote buttons combine a transponder blade with wireless lock, unlock, and trunk control in one unit. The G35 (2003–2008) and G37 (2008–2013) use the KR55WK48903 remote-head key with a PCF7952A ID46 chip and NSN14 blade. Both require NATS immobilizer programming through the OBDII port plus remote-signal registration. Canadian Locksmiths programs the transponder chip and wireless remote in a single visit, and NSN14 blade cutting is included with every remote-head key replacement.

The QX80 (2011–2024) uses CWTWB1G744 with a CR2025 battery. Every Intelligent Key hides an NSN14 insert blade in the housing for mechanical door access when the battery dies.

Pro Tip: Infiniti Smart Key Fob Care
Infiniti vehicles use advanced encryption that requires dealer-level diagnostic equipment to program replacement keys. The BCM key registration ensures secure key-to-vehicle pairing that cannot be replicated with generic tools. Keep the smart key fob away from electronic devices and extreme temperatures to extend battery life.
