could it be that the handle is spinning on the remote spindle? I compared my old original ones to a pair of NOS GM remotes, and the old ones the fluted spindle (or where the chrome handle goes on) are stripped down where they are smooth. If so, try a pair of vice grips , and see if they will unlock
There is also an adjustment for the remotes, shown in the shop manual
