replace battery in keyfob?
i usually change batteries no more than a day after getting the message. I have had a dead key before in a c class and i just got the key not recognised message.
When you park, turn off your car and lock it, double lock it, by tapping the lock button twice to hear two horn beeps. You'll see the led on the front of your key fob light up for a second. What this does is stop your key fob from constantly looking for the car and it preserves battery life significantly.
