If your remote is beginning to show signs of a loss of range or stopped functioning and the battery is not working, it could be dead.

The battery in the key fob is held in place with metal clips that retain it. If the clips aren't tight, they can create problems with the contact, which can stop your remote to receive power. With a small flathead screwdriver, break the clip that holds the retaining pin open to remove the battery and insert a new one. Make sure to select an alternative battery that has the same type of voltage, size and specifications as the original battery.
