This website www.reliable-store.com has the largest collection of repair, service, parts manuals of any vehicle on earth. Best website I came across for manuals.. Very helpful website

this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.

You either need to replace the battery(s) or reset the codes which should be in your owners manual

The title suggest the door won't unlock unless the remote is used but during the summer it was the inverse. If while inside the car the doors will not lock or unlock from the door but will from the remote then you have a faulty switch.If while outside the car the key turns while in the lock but the door won't lock or unlock then the linkage at the end of the lock is faulty. You'll need to remove the door inside plate to check this.

i dont think that your 04 camry has a remote start unless it is an aftermarket installed keyless entry
and remote start. my 03 toyota remote has lock,unlock,trunk onfront of remote and panic button on
the back that is red.

Check the car battery there is a battery in the remote as well but its to new to need to be replaced and so is the battery in the car It sounds most likely like there is a bad connection on one of the battery terminals on the cars battery if the bat is dead in the car the remote won;t work and if the bat is dead in the remote it won;t work but the car will hope this helps
