Identifying the battery type (CR2032)

The key fob for Alfa Romeo models like the 147, 156, and Stelvio uses a CR2032 battery. This flat coin-shaped battery is widely used in car remotes and small electronics. You can buy it at electronics shops or even grocery stores.

Check for “CR2032” markings engraved on your old battery to confirm its type. These batteries usually supply 3 volts of power. They are affordable and easy to find, costing about a few dollars each.

Always replace with the exact same type to maintain proper function of your keyless entry system.

3. Locate the battery plug. Turn it counterclockwise to remove it.
4. Use a flathead screwdriver to pry out the dead battery carefully.
