No it's a very simple task. Just you've to open center console and under ashtray all plastic trims. And two bolts are from top and two are underneath the car...
And you can remove the solenoid, give +12v battery to it and see if it clicks or not, see the pcb.. Maybe it has water damage marks and you can clean it with CTC or any contact cleaner, chances are it can start working. If not take it in market and find it used.
