How Infiniti Key Replacement Works in Windsor
Most Infiniti key replacements take just 30 to 60 minutes on-site – the bonded, certified, and insured mobile technician brings our key programming system, authorized Infiniti CONSULT dealer software, NSN14 blade blanks, and a complete inventory of Infiniti Intelligent Key fobs directly to your Windsor-area location. No towing, no dealer appointment, no trip to the dealer.
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 the details of your Infiniti – year, model, trim level, and whether it’s a push-to-start Intelligent Key or NSN14 transponder key ignition. Our team quotes Infiniti key replacement pricing from $99 (spare transponder) to $399 (all-keys-lost NATS7 recovery) and confirms which 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 emergency 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 emergency 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 with 2019, Infiniti switched from ID46 chips to 128-bit AES encryption (HITAG-AES / 4A chip) on select models, expanding across the lineup by 2020. The 2020+ QX60, QX55, and QX50 models with FCC ID KR5TXN7 require authorized Infiniti CONSULT dealer software to program – standard aftermarket locksmith tools cannot write the NATS7 128-bit encryption key. Canadian Locksmiths carries the same authorized dealer software platform that Infiniti of Windsor uses, performing Infiniti key replacement on-site at your Windsor location with factory-level NATS7 security. Older Infiniti models (2008–2019) use NATS6 with ID46 PCF7936 chips programmed via our key programming system through the OBDII port. Pre-2008 models use NATS5 with 4D60 transponder chips – both fully supported. Pricing: 2022–2026 QX60 KR5TXN7 Intelligent Key replacement starts at $249. 2014–2019 Q50 CWTWB1G744 fob from $249. G35/G37 KR55WK48903 remote-head key from $199. Every Infiniti key replacement includes NSN14 blade cutting, NATS programming, and 90-day warranty on materials.
Can you make a key for my Infiniti G37 or G35 without the original?+
Yes. The G35 (2003–2008) and G37 (2008–2013) use the KR55WK48903 Intelligent Key fob with PCF7952A ID46 chip for push-button start and keyless entry. Even with all keys lost, Canadian Locksmiths performs a complete NATS6 immobilizer recovery using our diagnostic equipment and authorized Infiniti CONSULT dealer software at your Windsor location. The all-keys-lost procedure connects through the OBDII diagnostic port, resets the BCM security module, erases all previously registered key codes so stolen or lost fobs cannot start your Infiniti, programs a new KR55WK48903 fob with fresh PCF7952A ID46 transponder signature, and cuts a precision NSN14 blade from VIN-decoded cutting data using the high-security precision key cutting mobile machine. G35 Intelligent Key replacement starts at $249, G37 at $269 – compared to $375 – $500+ at Infiniti of Windsor plus a dealer visit. The entire Infiniti key replacement process takes 45–60 minutes on-site with no towing required.
My QX80’s Intelligent Key works intermittently – the push-to-start sometimes doesn’t respond. What’s wrong?+
The QX80 (2013–2024) uses the KR5S180144106 or CWTWB1G744 Intelligent Key fob depending on model year, with a CR2025 battery powering the proximity signal. Intermittent push-to-start operation usually indicates a dying CR2025 – a $5 battery swap often resolves the issue. Canadian Locksmiths diagnoses the root cause on-site using the key programming tool connected through your QX80’s OBDII port: the technician reads the NATS immobilizer status, verifies fob signal strength, and checks how many keys are registered to the BCM. If the fob housing is cracked or the circuit board is water-damaged, our team supplies a complete replacement KR5S180144106 fob, programs it via authorized Infiniti CONSULT dealer software, and cuts a fresh NSN14 emergency blade using high-security precision key cutting machine. QX80 Intelligent Key replacement starts at $249 for spare key programming with a working key present, or $349 – $399+ for all-keys-lost recovery with NATS BCM reflash. In most cases same-day mobile Infiniti key replacement across Windsor and Essex County.
Is the Infiniti Intelligent Key the same system as Nissan’s?+
Yes. Infiniti is the luxury division of Nissan, and both brands share the NATS (Nissan Anti-Theft System) immobilizer platform across three generations: NATS5 (2003–2007, 4D60 transponder chip), NATS6 (2008–2019, ID46 PCF7936 chip), and NATS7 (2020+, 4A HITAG-AES 128-bit encryption). The BCM communication protocol, transponder authentication handshake, and key registration procedure are functionally identical between Infiniti and Nissan vehicles. Canadian Locksmiths uses the same professional-grade diagnostic hardware and authorized Infiniti CONSULT dealer software for both brands at your Windsor location. The practical differences are the FCC ID part numbers – Infiniti uses KR5TXN7, CWTWB1G744, and KR5S180144106, while Nissan uses different FCC IDs for equivalent fobs – and the NSN14 blade profile, which is shared across both Infiniti and Nissan platforms. Infiniti Intelligent Key replacement in Windsor starts at $149 for NATS5 transponder keys and $249 – $399+ for NATS7 proximity fobs.
What information do you need to start my Infiniti key replacement?+
Canadian Locksmiths needs the Infiniti’s year, model, and trim level to identify the correct NATS immobilizer generation and FCC ID. Push-to-start Intelligent Key vehicles (QX60 KR5TXN7, Q50 CWTWB1G744, QX80 KR5S180144106, G37 KR55WK48903) require proximity fob programming via our key programming system and authorized Infiniti CONSULT dealer software. Metal key ignition vehicles use NSN14 transponder blade blanks with embedded 4D60 or ID46 PCF7936 chips. Advise our team if all keys are lost or if you have a working key present – spare Infiniti key programming with a working key starts at $99 for transponder keys and $199 for Intelligent Key fobs. All-keys-lost Infiniti key recovery requires NATS BCM reflash ($249 – $399+) and takes approximately 15 minutes longer than spare key programming. Having your VIN ready speeds up the NSN14 blade cutting process on the high-security precision key cutting mobile machine. Call or text (519) 979-1270 for an instant 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 – no towing required. The mobile technician connects our diagnostic equipment to your Infiniti’s 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 your new Intelligent Key fob (KR5TXN7, CWTWB1G744, KR5S180144106, or KR55WK48903 depending on model), and cuts a fresh NSN14 blade using VIN-decoded data on the high-security precision key cutting mobile machine. All-keys-lost Infiniti key replacement pricing: QX60/QX55 NATS7 recovery from $349, QX80 NATS6 recovery from $299, G35/G37 recovery from $249, older NATS5 transponder recovery from $149. Because the mobile service comes directly to your location, there is no dealer visit to Infiniti of Windsor and no $150 – $250+ tow fee.
How long does Infiniti key replacement take on-site?+
Most Infiniti key replacements in Windsor are completed in 30–60 minutes once the mobile technician arrives at your location with our key programming system and authorized Infiniti CONSULT dealer software. Spare Intelligent Key programming with a working key present typically takes 15–25 minutes: connect to the OBDII port, register the new KR5TXN7, CWTWB1G744, or KR5S180144106 fob to the BCM, cut the NSN14 blade on the high-security precision key cutting, and test all functions. All-keys-lost recovery with NATS immobilizer BCM reflash takes approximately 45–60 minutes due to the additional security reset and verification steps – NATS7 vehicles with 128-bit HITAG-AES encryption require the longest programming cycle at approximately 50–60 minutes. Response time from your call to arrival: Windsor 20–40 minutes, Tecumseh 25–45 minutes, LaSalle 30–50 minutes, Amherstburg 35–55 minutes. Canadian Locksmiths dispatches Monday–Friday, 9am–5pm – text (519) 979-1270 for after-hours Infiniti key replacement arrangements.
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 frequency ( North America), transponder chip type (4A HITAG-AES for 2020+ NATS7, ID46 PCF7936 for 2008–2019 NATS6, 4D60 for older NATS5 models), button layout, and NSN14 emergency blade slot compatibility. These aftermarket fobs are programmed with the same authorized Infiniti CONSULT dealer software Infiniti of Windsor uses – your Infiniti’s NATS immobilizer cannot distinguish between our team fob and a $475 dealer fob once the transponder signature is written to the BCM through the OBDII port via our diagnostic equipment. The only visual difference is the Infiniti logo embossing on the housing. Aftermarket Infiniti Intelligent Key pricing: KR5TXN7 for QX60/QX55 from $249, CWTWB1G744 for Q50/Q60 from $199, KR5S180144106 for QX80 from $299, KR55WK48903 for G35/G37 from $199. Every fob includes the 90-day warranty on materials supplied and programmed by our team.

NATS5 vehicles (2003–2007) use the 4D60 transponder chip programmed via pin code extraction. NATS6 vehicles (2008–2013) use the ID46 PCF7936 chip with rolling-code encryption.
