Jeep Wrangler: KEYS / Replacing The Battery In The Key Fob

The recommended replacement battery is CR2450.

NOTE:

• Customers are recommended to use a battery obtained from Mopar®. Aftermarket coin battery dimensions may not meet the original OEM coin battery dimensions.
• Perchlorate Material — special handling may apply. See www.dtsc.ca.gov/hazardouswaste/ perchlorate for further information.
• Do not touch the battery terminals that are on the back housing or the printed circuit board.
• When a key fob battery is low, a warning will be indicated on the vehicle’s instrument cluster, and the fob LED will no longer illuminate with a button press.

1. Remove the back cover of the fob by inserting a flat-blade screw driver into the slot on the bottom of the fob. Pry until the cover unsnaps being careful not to damage the seal. Proceed counterclockwise to pry the remaining snaps until the battery cover can be removed.

WARNING!

• The integrated key fob contains a coin cell battery. Do not ingest the battery; there is a chemical burn hazard. If the coin cell battery is swallowed, it can cause severe internal burns in just two hours and can lead to death.
• If you think a battery may have been swallowed or placed inside any part of the body, seek immediate medical attention.
• Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children.
