cheap fix
I posted this on a previous thread- my key had broken away from the shell and this worked- still working today! might sound cheesy but it works-
Mine broke the same way- (Actually, when I bought my 98 recently the seller handed me the 2 broken fobs in pieces!) No way I was going to cough up the bucks for a new one. Used a small amount of JB weld inside to stick it together (clamped together w/ a c clamp) Then after the epoxy dried, I plastic welded the seam closed around the perimeter of the key (using donor material from the second failed part's shell) After I was done, I filed it down and sanded it smooth. Looks just like the original, except there is no seam between the halves
Obviously, once the transmitter battery (which I changed out beofre doing this!) dies Im s.o.l.. But till then, Im in good shape- Been using the key for 2 months now - No problems!
