Strange thing today, my driver's key now only works with the buttons and no longer allows me to open the door or tailgate 'keyless'. Also when I get in the car and try to start the engine it tells me the key isn't present. The only way to start the car is to hold the key in the recess left on the steering column. Also to stop the engine I have to hold the start/stop button in for a few seconds. Otherwise the buttons on the key work ok to unlock/lock the car. My spare key though works fine. I thought it might just be the battery, but put a brand new battery in it and still the same. Is there any way to "resync" the key, or is it likely to be more serious?
