If the key fob on your Alfa Romeo Tonale (2022–present) has lost its range or shows a low-battery message, the coin cell inside is almost certainly flat. It’s a quick swap with a CR2032.
Battery First — What You Need
- A CR2032 coin cell.
- A small flat screwdriver.
If the fob is completely dead you can still start the car: hold the fob against the START button as you press it. The emergency blade inside the fob unlocks the driver’s door.
Replacing the Cell
- Slide out the emergency key blade (release the catch and pull it out).
- Remove the key cover / split the case at the seam with a small screwdriver.
- Lift out the old cell (don’t touch the terminals).
- Fit a new CR2032, observing the correct polarity.
- Reassemble in reverse order and refit the blade.
Lost Key or Adding a Spare
A cell swap keeps the existing coding. A lost or broken key can only be ordered and coded by an Alfa Romeo dealer — there’s no owner programming sequence.
If a Fresh Cell Doesn’t Help
- Check the polarity — an upside-down cell won’t work.
- Hold the fob to the START button to drive in the meantime.
- Still flagging? A keyless-entry fault can store a code — look it up on autodtcs.com.
