⭐ The Honda Civic, CR-V, HR-V and Pilot 2022-2026 5-button smart key on part number 72147-T43-A11 is offered here as a used genuine factory Honda unit, working at 433 MHz and carrying a HITAG AES, ID 4A (NCF29A1M) transponder. Its buttons cover lock, unlock, hatch, remote start, panic. 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 72147-T43-A01, 72147-T20-A11, 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 Honda dealer system (i-HDS), or a locksmith key programmer whose software lists this model and year.
➕Add key (spare): connect over OBD with a working key present, pass the immobiliser security access, then register the new key with every key the customer keeps.
🔑All keys lost: the AES (4A) platform needs a tool with current Honda coverage, and some tools run the security access online; 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 Honda Civic, CR-V, HR-V and Pilot 2022-2026 smart key is in the tool's supported list before the job.
