If the key fob on your Abarth Grande Punto / Punto Evo (2007–2014) — the Fiat 199-based hot hatch — has gone weak or the central locking has become intermittent, 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.
The flip key turns the ignition mechanically even with a dead fob, so you can always start the car; the cell only powers the remote locking.
Replacing the Cell
- Flip out the metal key blade.
- Press the release and remove the screw to split the fob case (as marked on the fob).
- Lift out the old cell (don’t touch the terminals).
- Fit a new CR2032, observing the correct polarity.
- Reassemble, refit the screw and close 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 Abarth/Fiat dealer — there’s no owner programming sequence.
If a Fresh Cell Doesn’t Help
- Check the polarity — an upside-down cell won’t work.
- Use the key blade to lock/unlock in the meantime.
- Still intermittent? A receiver fault can store a code — look it up on autodtcs.com.
Frequently Asked Questions
What battery does the Abarth Punto key use?
A single CR2032 coin cell.
Do I need to reprogram the key after the swap?
No — the coding is retained for a battery change.
Can I program a new Abarth key myself?
No — a replacement key must be ordered and coded by a dealer.
The fob is dead — can I still drive?
Yes — the metal blade unlocks the door and turns the ignition.
If a warning light appeared after the battery went flat, look up the code on autodtcs.com.
