You state auto trunk button inop--am I correct to assume you already know the release in the trunk is OK? If it is the release button located in the glovebox. it easily removes and has 2 wires-You'll need a 12v test light or meter. One side will show 12v ONLY WITH THE IGNITION KEY IN THE ON/RUN POSITION. If the button is pushed with key on and the other side of the switch should also read 12v. If that all checks out, its a matter of following that wire to find the open.
put your key in the ignition turn it on , have someone push the trunk button while pulling up on the trunk catch
While in the auto open the glove box. With the ignition switch turned on press the yellow button inside to the left of the glove box. It should release the trunk lid. If it does not the trunk release or the wiring to it may be bad.
There is a trunk release button in the small console between the front seats...Press this button 2-times. When you open the trunk spray the latch with Wd40 or Lithimum grease you get at the auto parts store. This should help and keep it working for a good long time.
