Thanks for everyones input.
It does seem the problem is due to faulty integration relay board. Part No 82641YC091
My 2005 Camry Altise locks work fine atm in winter and we had a warm day 2 days ago and it would not lock but today its ok again as its cold.
I will be checking if there is a dry solder joint on that relay board and if its a faulty relay.
Does anyone know how to change the locking to 2 stage locking so the passenger doors lock first then the drivers door?
I have read this can be changed but not able to find the sequence online.
thanks
