Review on BOLT 7023582 Receiver Chevrolet Cadillac by Freddie Newton

Yes it has a key but I have access to three different GM keys. I programmed it (according to the instructions) with my new truck key. Each of the three keys opens the lock. I checked that the keys didn't open the doors of other cars, they don't open. That's a great idea! But actually it has to be blocked to be useful.
