Ah excellent you guys, i wasn't quite sure how that was working! I had a little craftsman pick set i picked up on clearance a while back that made pulling that retaining clip out very easy! Anyway, got one of the new lock cores in. 3 more to go. I think the others were just shot (either that or they were keyed differently...)
I bought some new lock cores from rock auto that came in 2 sets of 2, but the two sets are keyed differently. Can i take one set to a locksmith and have them match it to the other set so i don't have different keys for different door locks on my van ?
