How to Replace the Battery in a Toyota Tundra Remote

Model: Toyota Tundra Xk50 - Years 2007-2021
Part: Key

To replace the battery in a 2019/21 Toyota Tundra remote, first remove the physical key by pressing the rubber release button and sliding it out. Once done, insert the same key into the designated slot where it was previously housed and turn it to apply pressure on both halves of the remote to separate them. Once the remote is open, you will see the old battery that needs to be replaced, so remove it and insert a new one. Finally, close the remote by reversing the procedure. The required battery is a CR2032 3V.
