CR2412 key fob battery: which cars use it

The CR2412 is a 24 mm wide, 1.2 mm thick, 3-volt lithium coin cell. In this guide it is listed for 1 vehicle models.

Size code explained: “CR” is the lithium coin-cell chemistry; the first two digits are the diameter in millimetres (24 mm) and the last two are the thickness in tenths of a millimetre (1.2 mm).

Can I use a different battery instead?

CR2450 (5.0 mm) has the same 24 mm diameter but a different thickness. Use the code your fob specifies: a thinner cell can lose contact and a thicker one can bend the contacts or stop the case closing. Reddit threads about fobs that “won't snap on” or stop working after a swap often trace back to this.
