⭐ The Nissan Altima 2024 4-button smart key on part number 285E3-6LS1A is offered here as a new genuine factory Nissan unit, working at 433 MHz and carrying a HITAG AES, ID 4A (NCF29A1M) transponder. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. The same radio approval is fitted to 285E3-5RA0A, 285E3-6CA1A, 285E3-6LA1A, so the part number, not the FCC ID, decides the order.

🛠️ 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 locksmith tools whose software lists this model, such as Autel IM608 with APB131 adapter, Cgdi K2 with 15-Nissan/KR5TXN1/XN3 adapter.
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 Nissan Altima 2024 smart key is in the tool's supported list before the job.
