The battery inside of a Nissan vehicle key fob is a small, round, 1.5-volt battery. The electric key has three parts to it: the lower and two upper pieces. The key is held together by pressure. If the battery is dead, then the keyless entry and/or wireless start will not work. You will need one basic household tool to disassemble the key fob.
