Railroad68 Posted December 14, 2022 Share Posted December 14, 2022 After replacing the catalytic converter and O2 sensor - original stolen- the car no longer recognizes/responds to the electronic key fob. I have to use the metal key to enter the car when locked and I have to insert the electronic fob into the "key" slot to start the car. What can I do to get the key fob and car to interact?

CarterM41 Posted December 16, 2022 Share Posted December 16, 2022 Open the case again and readjust the battery, making sure the connections are clean and they're making contact with the battery. If the key fob still doesn't work, you may need to reprogram your Toyota key fob. Quote Link to comment Share on other sites More sharing options...
