Years ago I locked the keys in my Dart Sport (Hang Ten) parked on busy Egglinton Ave. in Toronto. I went into a couple of local shops begging for a wire coat hanger. Finally got one and got to the task at hand. Just getting the hook in place and interrupted by someone clearing their throat behind me. Seems the Toronto cop did not like what I was up to. I explained that I had accidentally locked the keys in my car. He wasn't buying it, so I had to prove it was my car. I pointed out that the ownership was in the glove box and I will have to finish up to comply with his request. Wrong answer, so now he C-PIC's my plate to find out who the car is registered to. New problem is my wallet and ID to identify that I am the registered owner is in the glove box, in the car, that has the keys locked in it. This could have been in an Abbot & Costello movie! Finally, he let me finish opening the door but then he retrieved the ownership and my wallet to verify I was on the level. All this took about an hour and I still had a 3 hour drive to get home.
Sorry for the thread hijack but your dilemma reminded me on mine from days gone by.
