Ok so basically I have to take it to the Toyota garage so they can scan it, is that correct. There is not much I can do to sort it out. I will try what you have suggested but there is no light on the dash. Also my secondary question on whether I can manually lock the boot has not been answered, I can lock all the doors manually which allows me to secure the car except for the boot. As I cannot get this investigated at a garage for a week I need to secure the car somehow as we are away from home...can you help with that? I have googled it and looked in the handbook but there is no info on locking the rear door. Thanks
Sorry I think you misunderstood, we can lock the boot with the key fob, but of course this sets off the alarm and so we want to try and lock the car without the key fob but couldn't work out how to lock the boot. However one of our neighbours has worked out a way we can do this so we can now secure the car. Thanks.
