used to have a thunderbird, cannot tell you how many times I locked my keys in, even in the trunk! it had a stupid self locking alarm.
havent done it in my truck yet, hopefully wont. but onstar would hopefully help out. If not AAA insurance will cover the cost of an unlock call ( have done that a few times)
Hope you get in, locking keys in like that sucks, puts you right into a shatty mood.
