⭐ The Honda Civic 2017-2020 4-button smart key on part number 72147-TBA-A01 is offered here as a used genuine factory Honda unit, working at 433 MHz and carrying a HITAG 3, ID47 transponder. Its buttons cover lock, unlock, trunk, 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-TBA-A11, 72147-TLA-A01, 72147-TG7-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 tool runs the immobiliser security access without a working key where its Honda coverage allows, 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 Civic 2017-2020 smart key is in the tool's supported list before the job.
