Electronic Door Lock.

Yes I have the same problem with passenger door . I was told the same , cost estimate $300 min, $50 just to diagnose at dealer. Independent says he can do it for about $280

I had the same problem with my 2005 Camry, the driver front and passenger doors didnt lock/unlock with the fob or the key, but the passenger sides were working. I was told it was the actuator on the door, found out how much the dealer was going to charge me $500.00 for one door(and I needed two doors). Then I looked on Amazon and found the actuator there for about $150.00, ordered it and changed it myself. Took about 30-45 minutes, and its the same part that came off the car. Save some money and check Amazon first! So I changed both doors for under $300.00. Check out youtube and serach changing actuator on 2004 toyota camry on your make and model, well worth it.
