A month ago I bought a keyless remote for my '01 OBW and the service manager was
kind enough to program it for me. Last night my car was "prowled", as the
sheriff's office put it. No damage to the car or apparent attempt to steal it,
but stuff on the inside, including the glove box, was thrown around and a pair
of binoculars was missing. There was no sign of forced entry

I have no clear memory of locking the car yesterday evening. I also have no
clear memory of brushing my teeth last night, but I'm sure I did since I always
do; it's a deeply ingrained habit. So is my locking the car.

I'm wondering if I just forgot to lock it, or if the keyless entry can be
hacked. Is it possible/easy to do? Of course it shouldn't be, but I think I read
once that General Motors, at one point in its history, used only 35 key shapes
for all of its cars. Thus, if you wanted to steal a GM car and had a key for
one, you only had to try on average 35 GM cars before you could get into one.

Thanks,
