Nissan Key Fob Battery Replacement Cost & Cheap DIY Method

If you want to know the Nissan key fob battery replacement cost, you are in the right place. This article will show you how to do it yourself and all the costs involved in the process.

Key fob batteries tend to die every three to four years on most Nissan models. I used to own a Nissan Altima myself back in 2014, and the battery in my key fob had to be replaced every two years.

The first time this happened, I had no idea about the costs involved in replacing the battery in my key fob. I took it to the dealership, and they quoted me $75 just to replace the dead key fob battery.

Luckily I had a second key fob that did not need a replacement battery, so I used that one until I could find a more affordable solution.

After researching the correct battery type, I found a new battery multipack for my key fob online for under $5 USD. I replaced the old battery myself in less than five minutes, and it worked great for another few years until the battery finally died again.

What Kind Of Battery Does A Nissan Key Fob Have?

There are three main types of batteries used in Nissan key fobs: the CR1620, CR2025, and CR2032.

Depending on the Nissan model and year, your key fob might use either of these batteries. The best way to find out is to look up the owner’s manual or simply crack open the key housing of the fob and check the battery inside.

If you do it yourself, all you need to do is buy the same battery that your Nissan key fob uses and replace it with the old one. These CR1620, CR2025, and CR2032 batteries can be purchased in a multipack for $2.99 to 12.99 USD.
