Ok alittle over a week ago i went out to my car unlocking it with the keyless, when i went to open the door it locked the doors because it would only unlock half way. I have to unlock it by key now. When i start the car the doors will unlock and lock all i want. so i thought maybe it was the battery. I'm getting 12.5 volts with the car off and 14.5 when it is running. do you guys have any ideas?
