About RLX Keys
Verified key reference for the Acura RLX — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| RLX | 2014–2020 | Smart key (proximity) | Hitag3 ID47 | HON66 |
Security System & Immobilizer
Acura runs Honda’s immobilizer architecture — ID46-era transponders through current Smart Entry proximity fobs.
On the RLX specifically we see: Hitag3 ID47. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Acura RLX Key FAQ
I lost the only key to my RLX. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.
My RLX is push-to-start — can you program that outside the dealer?
Yes. Late models (2014–2020) use a proximity smart key on Hitag3 ID47 — we carry the fobs and the programmer, and we cut the emergency blade.
