There is no known cheat for a tow truck. I tried it a few times and it never worked.

You can't break into locked cars, but if you get a tow truck and tow the locked car into one of your garages and save the game, the car will be unlocked.
The tow truck is the truck used to pull other vehicles. The one in the game does exactly that and can be found in industrial areas and commonly at the airport on the first island.
There does not seem to be any mechanism in play to use a tow truck in GTA IV. I have tried many times to hitch up to a trailer with a tow truck, but it doesn't work.
