Help W/ Opening Doors W/O Key In (Inside car)

Hi!
I have a 2009 Toyota Tundra and recently I’ve been unable to unlock/lock the doors (from inside) with the power button without the power on. It helps when I take the keys out while my husband puts in gas and lock it with the power button, but I have to manually lock and unlock them all. It’s quite annoying and would like to know if anyone has had that problem and knows how to fix it. I can do it myself and would like to avoid taking it somewhere to have someone else fix it.
Thank you!

 

First, Welcome from LA (Lower Alabama)! It sounds like a relay that provides power to the lock actuators has gone bad. You can find the wiring diagrams in this thread:

Check to see if you fall under the TSB if you do make an appointment at your local dealer and take the TSB with you.
