Hi I'm new here and ask for your patience. I tried to indroduce myself but ran into problems on the intro page. I've read all posts on this thread, and I too have central locking problems with a 2004 Camry Altise - works sometimes and others not. In the problem situation, when locking with the remote, the horn chirps twice and the indicators flash twice, indicating a door open. Also, locking the drivers door manually with the key only locks the driver's door, not the others. A locksmith was unable to doagnose and rectify the problem. Other posts also indicate that getting specialist service would be a waste of money. Whilst attempting self-diagnosis I discovered that the lock knob (the button you can move forward to lock the door, or backwards to unlock) on the passenger door behind the driver was in a disconnect state - it basically flaps in the breeze and is clearly not attached to anything. I would like any comments on the effect of this - would it explain the problems described above? I can see that if the pin switches on the doors (as referenced by the-random-hero) were inoperative the security system would detect a door open situation, but would a disconnected lock knob have the same effect? At the moment I can manually lock all doors except the passenger door behind the driver, which is a pretty bad security situation. Cheers
