I have a V40 2010 with the keyless system. I'm getting a low key battery message intermittently. I've change the battery in the both keys but continue to get this message. My mechanic says there are no messages in his devise to determine what's happening. Also, I'm told I must step on the brake peddle to start the car, but this is not the case with this car. Any ideas what's going on? I'm wondering if there is some car computer thing issue.
