🔧 PRO TIP
The 2020 RLX smart key (KR580399900) runs on Acura's Hitag 3 / 128-bit AES immobilizer, same protocol Honda rolled across the lineup in the mid-2010s. A weak CR2032 throws "KEYLESS START SYSTEM PROBLEM" on the dash and kills the push-button range before the lock/unlock buttons even feel slow. But the immobilizer data lives in the car's EEPROM, not the 12V battery. If the car sits dead for weeks and you jump it, the key pairing is still there. It is the voltage, not lost programming.

2020 Acura RLX Smart Key Replacement - Fast, Affordable & Professional

Over in the Mountain View neighborhood in Fillmore, a college student flagged me down between classes. He had just picked up a 2020 Acura RLX from a private seller. One key. The seller swore a spare would be cheap. The Acura dealer quoted him a number that wiped out what was left of his savings after buying the car.

He found me online and asked if that was normal. I told him it was. Dealers charge what they charge. I do the same work for a fraction of that because I do not carry their overhead.

I met him at the lot. His RLX runs the KR580399900 proximity fob, part number 72147-TZ3-A51, with the Hitag 3 AES transponder on the 38901-TZ3-A01 board. I used my IM608 to pull the key data through the OBD port on the driver's side, registered a new smart key to the system, and cut the emergency insert blade by decoding his door cylinder. The whole thing took about 25 minutes.

While I worked, I walked him through the difference between add-a-key and all-keys-lost. Right now, with a working key present, it is a quick registration. If he ever loses both fobs, the reset involves a pin code pull and a timed security countdown that doubles the labor. Knowing that usually convinces people the second key pays for itself.

He drove off with two working fobs and never missed a class.

Acura RLX Mobile Service FAQ

Real costs, no dealer surprises

I am locked out of my 2020 RLX with no spare. Can you come to me in Fillmore?
Yep. I carry the key blanks, the fob shells, and the diagnostic gear for the RLX right in my van. If you are in the Mountain View neighborhood or anywhere in Fillmore, I come to you. No tow truck, no waiting room. On a lockout, I can get you back inside the car and, if you need a replacement smart key, program and cut it on site. The whole job from arrival to handing you a working fob usually runs 25 to 45 minutes depending on whether it is add-a-key or all-keys-lost.
Do I need to tow my Acura RLX to a dealer for a new key?
What do I need to prove I own the vehicle before you make a key?
My RLX dash says "KEYLESS START SYSTEM PROBLEM." Does that mean I need a new key?
I bought a replacement KR580399900 fob online. Can I program it myself?
