Even though it last happened last Monday, I haven't been able to duplicate it. I even held a key a few inches from the handle with no results. I am going in for my 25K maintainance next week (yes I put a lot of miles on my car) and will ask about it. I am sure the dealer will say nothing is wrong with it and it is the way I walk, but it is worth a try. BTW, I am not sure how you reset the lock with the manual key, can't find anything about it in the owner's manual. Is it just unlocking the door with the manual key?
I think they mean hit the lock button, and unlock button on your key...
