Acura ILX Key Replacement

Acura ILXs have been on Dallas–Fort Worth roads since the 2013 era, and across 2 key generations this model has used 2 different key systems — remote-head / smart key; smart key (proximity). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.


About ILX Keys

The table below is our verified key reference for the Acura ILX — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.

ILX2016–2022Smart key (proximity)Hitag3 ID47HON66

Security System & Immobilizer

Acura runs Honda’s immobilizer architecture — ID46-era transponders through current Smart Entry proximity fobs — with the same on-site programming paths.

On the ILX specifically, the immobilizer families we see are: Hitag2 ID46, Hitag3 ID47. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Which key does your year have?

  • 2013–2015: Remote-head / smart key — Hitag2 ID46 (HON66)
  • 2016–2022: Smart key (proximity) — Hitag3 ID47 (HON66)

Acura ILX Key FAQ

I lost the only key to my ILX. 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 — this is our most common ILX call.

My ILX is push-to-start. Can you really program that outside the dealer?

Yes. Late-model ILXs (2016–2022) use a proximity smart key on the Hitag3 ID47 system — our trucks carry the fobs and the programmer. We cut the emergency blade too.

How fast can you reach my ILX in DFW?

We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
