Unlocking and Starting Your Toyota When Your Smart Key Malfunctions

Your Toyota Smart Key has a traditional metal key housed inside of it in case the key fob battery ever dies. All you need to do is push the button on the bottom of your key fob to gain access to the metal key. Then, unlock your doors in the traditional manner. To start your car, depress the brake and push the start button like normal while holding the key fob as close as you can to the start button. This should help a weak battery signal reach the car allowing you to start it right up. Just don’t forget to replace your battery before the fob is completely dead.

Changing the Battery

To change the battery in your Toyota key fob, take the metal key outside of the fob and then use the opening left behind to gently pry the fob open. Inside, you will find a small green circuit board that houses the small battery. Pop the old battery off and replace it with a new battery. Then, put your key fob back together and re-insert the metal key and it should be as good as new.
