Pouring warm water on the lock won’t help if the ice is coating the whole car. Here it rained the froze.Only about 1/4 or so thick. Not even close to 1978 when pouring rain quickly froze turning running water into 4 inches thick trapping my pickup in the driveway.
The locks open....the handles won’t budge to open the doors.
I just read on line to use a d-icer like one usd on windshield.....or make one of alcohol and water. I have both so I’ll try those.
