⭐ Built for the Honda Accord 2018-2020, this 4-button smart key is a new genuine factory Honda unit of part number 72147-TVA-H2, running at 433 MHz with 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 72147-TVA-A01, 72147-TVA-A11, 72147-TVA-A21, 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 HON66 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 Accord 2018-2020 smart key is in the tool's supported list before the job.
