Raer deck lid will work intermittently and ten not work from inside car or by key fob for several days. Beeps twice and won't open or close automatically.

 

2 things to check, look to see if your vehicle has the rear hatch disengaged through the MID dash controls, then check to see if your glove box has the trunk lockout button, if those don't get it. Check to see if the rubber rear hatch button isn't damaged or melted, if it is damaged or melted that's most likely the cause
