I feel for you, I have been in your shoes many times over the years. I have done everything from the Coathanger trick to calling AAA. Day before yesterday my wife called me from Walmart telling me she had lost her keys. She thinks she left them in the buggy but by the time she realized she needed her keys someone was pushing them around the store. I had to go to Walmart with our spare set that came with the car. Luckily someone turned them in and she was able to retrieve them yesterday.
