I had the same thing happen to me a couple of day ago. When we approached the car the trunk wouldn't open at first, after a couple of tries it opened. Then when we tried the door handes it would not unlock. I used the key and the alarm went off. After entering the vehicle and trying the start button the doors locked and the alarm continued. I set my remote in the small tray in front of the cup holder and it was no help. I remembered seeing what looked like a key slot under the mat of that tray when I test drove another Cruze, so I pulled the mat up and stuck the key in and tried to start it. At that point it started and the DIC said "theft attempted!". Since then both remote seem to be working fine.
