🔧 PRO TIP
The 2019 ILX smart key (FCC ID KR580399900) is a two-way fob running in the 902-928 MHz band with DSSS and FSK modulation, not a simple one-way clicker. The Continental PCB inside is marked 40646000-02. It carries an ID47 (Hitag AES) transponder chip for immobilizer authentication. A weak CR2032 can mimic bigger problems: "KEY NOT FOUND" on the MID, passive entry dropping out at normal range, or the start button cycling to ACCESSORY instead of cranking. Swap the CR2032 first, but check that the battery contact tabs are straight and making solid contact.

2019 Acura ILX Smart Key Replacement - Fast, Affordable & Professional

In Ventura, over in Mission San Buenaventura, a 2019 ILX owner had already done the classic first move: fresh CR2032. The remote still acted up.

Lock and unlock worked from across the lot. But the start button was coin-flip territory. Sometimes it went to ACCESSORY, sometimes the dash just sat dark. They kept pressing the fob buttons anyway, like repetition was going to fix it.

I ran through Acura's one-push start diagnostic order on site. Fob LED lit on button press, doors responded to lock and unlock. Then the backup proximity test: foot off the brake, press the engine start/stop button, hold the fob against the start/stop button when the MID prompts. The LED blinked, went solid, and the dash powered up. So the low-frequency coil antenna in the steering column was still reading the ID47 transponder at close range, but the RF side of the fob was failing intermittently.

When I split the case, the water detection sticker on the inner panel was solid red. Moisture had gotten in. That fob was done.

I programmed a replacement KR580399900 to the car, cut the emergency insert key, and erased the old fob from the system so it could never start anything again. Then the boring part that tells the truth: testing lock, unlock, trunk release, remote start, passive entry on both front handles, and Walk Away Auto Lock. Every function, every door, twice.

They didn't need to tow it to anyone. Just the right fix, on site, for a fraction of what a dealer visit would have run.

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Acura ILX Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Acura dealer for a 2019 ILX smart key replacement?
No. A mobile auto locksmith with the right diagnostic tools can handle this where the car sits. The 2019 ILX smart key uses an ID47 (Hitag AES) transponder that has to be registered to the immobilizer through the OBD-II port. There is no self-programming trick or ignition cycle sequence for this system. The OEM part numbers are 72147-TZ3-A51 (Driver 1) and 72147-TZ3-A61 (Driver 2), both FCC ID KR580399900, five-button, CR2032. After programming, I erase any missing fobs so they can no longer start the car.
What does the smart key actually do on a 2019 Acura ILX?
How long does a dealer take for 2019 ILX key replacement, and is it faster than a locksmith?
My 2019 ILX shows "KEY NOT FOUND" but the fob battery is new. What is going on?
