My key won’t unlock the car, is the battery in the key fob low? [450]
It could be. It's more likely that the key has fully discharged, lost its coding and will have to be re-coded along with the car and any spare keys you might have. Try to use both keys equally and often to prevent losing the coding. There has been no satisfactory explanation as to why they do this. If the battery is low the indicators will flash 9 times quickly (indicating you can use it 100 times more - so change the battery asap). When changing batteries observe correct polarity and change them promptly. Batteries are available in many retail outlets and garages. Battery size is CR1225 (except for the City Coupe 600cc, which has a 1 button key and takes a CR2016). See the handbook for how to replace the battery.
My Smart car key unlocks the car but won’t turn off the immobiliser, why?
It likely the key has lost its coding (9 indicator flashes should accompany this when pressing the key fob unlock or lock button if it's faulty) and will have to be re-coded along with the car and any spare keys you might have too. They all will have to be taken to someone with a Star Diagnostic machine to re-code them all together. Its worth getting an additional new key before so you can get it coded at the same time, if you don't already have a spare key.
