Which Honda Civic does the 72147-TBA-A11 smart key fit?

The 72147-TBA-A11 smart key fits the Honda Civic 2016-2021 with the 5-button layout, North American version. Match the part number printed on the back of the original key, and the button layout, before ordering. Keys for the same car can differ by trim, market and button count.

Is the FCC ID enough to pick the right key?

No. The FCC ID KR5V2X is a radio approval that Honda also uses on 72147-TBA-A01, 72147-TG7-A11, 72147-TGG-A21. Those keys can fit other cars or have other buttons, so the part number 72147-TBA-A11 on the original key is the deciding reference.

What frequency and transponder chip does the 72147-TBA-A11 key use?

The 72147-TBA-A11 smart key transmits at 433 MHz and carries a HITAG 3, ID47 transponder inside the housing. No separate chip is needed, but the key must be registered to the car with a diagnostic tool before it unlocks the doors or starts the engine.

How is the Honda Civic 2016-2021 smart key programmed?

The Honda Civic 2016-2021 smart key is programmed over the OBD-II port with the dealer system or a locksmith key programmer that covers this model. Registration runs through the immobiliser security access, which the tool performs or the dealer system obtains online.

Is the emergency blade included with the 72147-TBA-A11 key?

No. The 72147-TBA-A11 smart key is supplied as the key only, without its emergency insert blade; it takes a HON66 profile blade. Source the blade separately and cut it to the vehicle's key code, by code or by decoding the door lock.

Is this 72147-TBA-A11 key a genuine Honda part?

Yes. This listing is a genuine factory Honda 72147-TBA-A11 smart key, supplied new and unprogrammed, without the original dealer box, without the emergency blade. It is programmed to the car over OBD like any new key. Match the part number on the original first.

Which battery does the 72147-TBA-A11 smart key take?

The 72147-TBA-A11 smart key runs on a CR2032 coin cell battery, fitted inside the housing. Replace it when the range drops or the dashboard shows a low key battery warning. If the battery is flat, hold the key against the start button to start the car.

🛠️ 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 2016-2021 smart key is in the tool's supported list before the job.
