Before buying a battery
Choose the battery for your actual Fit key
Match the original remote housing, then keep the right battery and tool plan together.
Before you start
Keep coin cells away from children and pets. A damaged, wet, corroded or aftermarket remote needs identification or service before opening.

For an owner preparing to replace a weak remote battery who has not yet matched the key type. Other model years, markets and engines need their own manual.
Identify my remote and save the planMatch the housing first
The original screw-fastened remote and the Smart Entry removable-key remote use different cells. The model name alone is not enough.
Manual: PDF page 397
Keep the choices together
For the original screw-fastened remote, the manual specifies CR1620; for the original Smart Entry remote, CR2032. Use the matching opening procedure and tools.

Leave with a preparation record
