i kinda really wish i had one, my last car didn't have one either and i locked the keys in it twice! But the car had those little triangle shaped windows in front of the regular ones, and the one time i locked the keys in i reached in and turned the crank for the traingle window until i could reach in and get the lock.
The other time though i had to call a tow truck (cause i was waiting for the locksmith to get my keyblanks in for a second set)
Luckily someone with me had a CAA card
(which is the canadian AAA)
