okay so heres the deal, get to my girlfriends house lock the car... dont know why usually dont know one is around her house. so we watch oceans 11 and i come out to take her to take care of some animals and notice i cant unlock my car from the drivers side... the key will go in but it just wont turn, either way. so i go over and i unlock from my girlfriends side. she gets in i then try to lock it again, and then drivers and passenger side wont lock it. i then go to the trunk and the whole car locks, but the trunk wont unlock it, as usual neither of the doors will either. shes freaking out becuase she cant pull the locks up either to unlock it, i get the trunk to unlock but the rest of the car wont, so i have her open up the backseat and i pass her the keys through the backseat (where it opens) and she turns on the car and the doors unlock... we then open the sunrof to try it again... same thing happens where only the trunk locks it and then try to unlock and only the trunk will unlock. both drivers and passenger side, the key wont even turn... i say screw it and we go take care of the animals (i am PIST AND WORRIED BY NOW) as we are driving i lock and unlock the car with the inside knobs... we get back to her house and i leave her in the car to try it one more time... and what do you know it locks and unlocks... key turns fine. so heres my question.... WHY! haha i know the locking system has to due with power. like if you battery is disconnected you ahve to lock one door at a time... my power isnt always steady, (like when i move my power seats back and forth i can feel the car draining ofpower and my headlights dim, same with when i push up on two window switches when they are already up... so could it be power related... and ican get ready for an electrical faliure... or could it be because of the cold? which sounds weird... it was 30degrees all day today... this is worrying me any help would be awesome!
