⭐ This is an aftermarket replacement: a 4-button smart key for the Acura TLX, ILX and RLX 2015-2020, Acura part number 72147-TZ3-A01, transmitting at 313.8 MHz with a HITAG 3, ID47 transponder. Its buttons cover lock, unlock, trunk, panic. It ships with a HON66 emergency insert blade and is registered over OBD with a diagnostic tool. The same radio approval is fitted to 72147-TZ3-A11, 72147-TX6-A22, 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 Acura 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 Acura coverage allows, then each key is registered in the same session.
Blade: cut the HON66 emergency blade 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 Acura TLX, ILX and RLX 2015-2020 smart key is in the tool's supported list before the job.
