Extending the Life of Your Key Fob Battery

Here are a few tips to help your 2007 Toyota Tundra key fob battery last longer:

Avoid Extreme Temperatures: Extreme heat or cold can shorten battery life.
Don’t Keep Your Keys on a Metal Keychain: This can create a circuit that slowly drains the battery.

“Keeping your key fob away from extreme temperatures, like leaving it in a hot car during the summer, can significantly extend its battery life,” says John Peterson, an automotive electronics specialist with 20 years of experience.

How Much Does a 2007 Toyota Tundra Key Fob Battery Replacement Cost?

The cost of a CR2032 battery is typically very low, usually between $2 and $5. Replacing the battery yourself is the most cost-effective option. If you choose to have a dealer or automotive technician replace the battery, expect to pay a slightly higher price, potentially including a labor fee.
