Broken wire in the wiring harness by the right hand trunk hinge. Pull back the black rubber gasket and you'll find a set of wires and the lock button one is broken. You can splice it but others will prob break too. Not expensive to get the wiring harness to replace it - maybe $80 or so, I can't quite remember

 

Good stuff. Thanks for all of the help.

 

You're welcome! Hopefully you can enjoy the car now!
