Before you order
Confirm the printed battery size.
Most key fob batteries have the size stamped on the cell. If the label says CR2354, this is the replacement pack to choose.

Two fresh 3V coin cells.
Use one battery now and keep the second one as a spare for another remote or the next replacement cycle.
- CR2354 lithium coin cell size

How replacement works
A simple swap for most key fobs.
Open the remote case, note the battery orientation, replace the old cell with the same size, then test lock and unlock range near your vehicle.
Ready when you need it
Small product, important backup.
A weak key fob battery can reduce range or trigger warning messages. Keeping a spare helps avoid a surprise dead remote.
