In the majority of cases an alternative key fob battery can be found in an auto parts shop or on the internet. Whether you're replacing the battery for a newer or older model, you must follow the instructions provided by the manufacturer to ensure a smooth experience.
When removing the battery from your key fob, keep in mind that many key fobs have a mechanical backup key. The key is used to open the driver's side door in the event of the battery being dead. The backup key is accessible by pressing the small button that slides on the back of the key fob.

Physical Damage

If this is the case moving your mouse away from these devices or to a new location could resolve the issue.
