CR1616 key fob battery: which cars use it
The CR1616 is a 16 mm wide, 1.6 mm thick, 3-volt lithium coin cell. In this guide it is listed for 8 vehicle models.
Can I use a different battery instead?
CR1620 (2.0 mm), CR1632 (3.2 mm) have the same 16 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.
