So, today I tried to drive my 04 xlr to winter storage. I opened the door. put the car cover in the passenger seat, put the fob into the cup holder closed the door. I then unhooked the battery tender. The horn beeped (never did that before). Went to open the door and it wouldn't open. Got my spare key and tried it. Still won't open. Red light shines on driver door. Now what? can't open car to get it towed to dealer for resolution. Any ideas???? ps....................this car is wonderful when it's running but, very unreliable.
