How to tell which key your Acura ILX uses
- Push-button start: your car uses a smart key (proximity key) with no metal blade to turn.
- Turn-key ignition with lock/unlock buttons on the key head: your car uses a remote head key.
- Separate remote plus a metal key: the remote and ignition key may be separate parts. Confirm whether the ignition key needs a transponder chip for your vehicle.
- Not sure? Read the FCC ID on your current key, or look up your key by VIN and see our FCC ID lookup guide.
Cutting and programming
UrbanX keys are aftermarket replacements, not OEM. Keys with a metal blade need to be cut, and most remotes, smart keys and transponder keys need to be programmed to the car by a locksmith or dealer; some older models allow on-board programming. Eligible items can be returned within 90 days.
