How much does a new glovebox liner for one of those cars cost? You could cut the liner and remove the lock. Back in the day the parts managers could re-key the locks. Back in the day when I had multiple cars I had them all keyed the same. FYI, I have glovebox locks and matching keys if someone needs one but taking the existing glovebox lock to a locksmith might be a better option since the glovebox lock might match other locks on the car.
