Acura TSX Key Replacement
Acura TSXs have been on Dallas–Fort Worth roads since the 2004 era, and across 1 key generation this model has used 1 different key system — transponder / remote-head key. 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 TSX Keys
The table below is our verified key reference for the Acura TSX — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| TSX | 2004–2014 | Transponder / remote-head key | Philips ID46 (Hitag2) | HON66 |
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 TSX specifically, the immobilizer families we see are: Philips ID46 (Hitag2). 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.

Acura TSX Key FAQ
I lost the only key to my TSX. 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 TSX call.
Will a hardware-store copy start my TSX?
It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.
