Well bit of an update. I sent my one set of keys off to be repaired. I had to post them to a firm quite a few miles away, http://www.autotronics.co.uk/cscart/index.php I had a call today to say they had fixed the "bad key" issue, he said there was water damage and I needed a new chip. Cost £75 (approx $100) which includes posting them back. No idea what caused the water damage but I believe him. Should be back by Friday.
Second key which started the car but wouldn't lock the doors is also now fixed. I got handed a business card at a garage today for a locksmith. I called him and he asked if I had fitted a new battery, which I had and then he told me how to resinc the key, he said sometimes when a new battery is fitted it need it be connected to car again.
To do this you hold down the lock button and then place it in the ignition (keeping the lock button pressed down) . You turn the key until all the lights are displayed on the dashboard. You keep the key there for 10 seconds' (still holding down the lock button ) and then you turn the key to the off position and take the key out. You still keep the lock button pressed and you hold it for ten second before releasing it.
This worked and my key started to work again unlocking and locking the car. I was staggered he told me for free over the phone!!! It worked several times and then started to fail to lock on a few attempts so he came to the house and opened the key fob case. Again I had some water damage and a connections needed repairing. Now it seems to be working fine, Cost for this key £45 (approx $70)

I'm thrilled my key which showed "bad key" error is now fixed!!!!! Not only is it fixed the key now looks like a new key with new casing!!! Cost £67 plus £10 for postage via courier. £77 ( $110) for what looks like and works like brand new key. Save me hundreds!! He accepts international enquiries, shipping etc.
We can't get spare keys in the uk to program cheaply so this is amazing value x
