I have 4 keys to my 1994 S-10 Bazer. 1: Ignition 2: Drivers door 3: Passenger door 4: Rear window/tailgate. I'd like to buy 3 matching locks to put on the drivers, passenger door and on the tailgate. GOAL: to go from 4keys to 2. Can any one point me in the right direction getting the 3 lock mechanisms?? Thanks, Rob
