volvo key issues

Question by Todd posted 7 months 2 weeks ago in XC90

So I bought a s/hand xc90, 2011 model with 65,000k's on it about 21/2 years ago, have done 70,000k's.

About a year ago we had an issue that seemed that the car wouldn't turn over when it was hot, after a year (new starter motor, battery good, new key tumbler) it turns out, if the KEY is over, roughly 16 degrees, the car comes up with a "key status not recognised" but no actual error. You chill the key (butane works as well to freeze it) and it will start EVERY time. It never stops once going either, its a nightmare, any ideas?
