Should You Get a Replacement Key Fob Acura?

When you buy your Acura car, it should come with a key fob.

But these two small remote designs aren’t perfect. For example, at some point, they may not open and close your doors like they used to (that is, you have to hold them super close to the sensors).

Don’t make the mistake of immediately shopping for a replacement. Instead, realize that a dead fob battery might be the culprit.

Replace the Fob Battery Yourself

Replacing fob batteries is easy. To start, take out the metal blade. Then, use a screwdriver to open the tab, remove the old battery, and insert the new CR2032 Button Cell battery (+ side up).

Then, close the tab and reinsert the metal blade. Note that the Acura Keyless Remote design requires two batteries, while the Smart Key only needs one battery.
