⭐ The Infiniti QX70 2019 4-button smart key on part number 285E3-1CA8D is offered here as a new genuine factory Infiniti unit, working at 433 MHz and carrying a HITAG 2, ID46 (PCF7952) transponder. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. Infiniti also lists 285E3-1CA7C, a different key (Documented 433 MHz Europe / Middle East 4-button FX / QX70 key (2008-2014)), so match 285E3-1CA8D on the original key.

🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

This proximity smart key cannot be learned by hand. It is registered to the car through the OBD-II port with a diagnostic tool.

Compatible tools: the Nissan CONSULT dealer system, or a locksmith key programmer whose software lists this model and year.
Add key (spare): connect over OBD, read the BCM challenge and calculate the PIN, then register the new key together with every existing key the customer keeps, because registration erases all stored keys.
All keys lost: the BCM PIN is calculated from the challenge code first, then each key is registered in the same session.
Blade: cut the emergency blade, sourced separately, to the vehicle's key code and test it in the driver's door.
Check coverage first: support depends on the tool's software version and the exact model year. Verify the Infiniti QX70 2019 smart key is in the tool's supported list before the job.
