battery for key

[Jostudly]

I have noticed lately my doors do not always open right away when I use the unlock button on my key. The horn also no longer goes off when I lock the doors. I am wondering if I need a new battery and if so what type of battery do I need?

There is a small LED on your keyfob. If it glows dimly when pressed, the battery is likely dead. Mine started to go a month ago. If I left my keys outside in the cold (ie coat pocket), the remote wouldn't work at all.

The horn also no longer goes off when I lock the doors.

Read pg 3-8 of your owners manual: "Setting hazard indicator and horn mode"

I am wondering if I need a new battery and if so what type of battery do I need?

Regular fob battery: CR1620
Intellikey battery: CR2025

Instructions for battery replacement start on pg 8-21 of your owners manual.

Do I need to get the battery from Nissan?

There are common battery sizes. You can find them at places like Radio Shack, Wal-Mart, or places that sell watch batteries. I found the CR1620 is harder to find, only Radio Shack (The Source in Canada) had them.
