2015 Honda Crosstour Key Fob Programming
Updated 2026 Programming, battery & replacement fob
The 2015 Honda Crosstour key fob can't be programmed at home — it needs a locksmith or dealer with a diagnostic tool. Below is the exact replacement fob you need (FCC ID and part number) and what to expect.
Professional programming required
This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.
Replacement key fob
Match the FCC ID printed on the back of your existing fob to be sure of the right part.
Transponder Key

A plain transponder (chip) key has no battery. The immobilizer chip inside is powered by the car's ignition ring whenever you turn the key, so there's nothing to replace. If your key also has lock/unlock buttons, that remote portion uses a 3V coin cell — see the remote battery steps for that.
Battery tips
- If your engine won't start but the key turns, the issue is usually a worn key or the immobilizer reading the chip — not a battery.
- A spare chip key must be cut and programmed to your car before it will start the engine.
