ANYONE who has had problems with territory starting?? help

Hi all,
We brought our territory new in end of 2010.
A couple of months ago my husband drove into town, got out and when he got back in all lights would come up but nothing happened. Called RACV and they told us that sometimes computer gets confused and dosnt register the key or something like that????? after about and hour it started and has been fine till now.
Yesterday took the boys to hockey and then drove home. Went to start it again and nothing, got spare key and waited a while..... nothing. rang RACV who is actually our mechanic and he said I think its the box and not they key diconnect the battrey and see if this helps... nothing. that was yesterday morning and as of last night its still not starting.
Has anyone ever had this problem and what was the outcome?
It is still under new car warranty
Thanks

I haven't had this happen personally with my Territory, but if you google the car and "complaints corner" a website with common problems comes up. All the posts are by owners of the car and often how it's been resolved. Good luck!

So annoying - nothing worse than getting stuck with a car not starting & even worse when you have the kids too. This was happening with my commodore wagon. I had to get my keys reprogrammed by a holden dealer. This was over 12 months ago and I haven't had a problem since.

Good luck.

DH's territory once flicked the fuel cut-off switch, unknown to him, so was stranded away from home until it was towed to the mchanics on Monday morning. We still don't know how it happened. He's not impressed with his a territory.
