Inspiration? You mean assistance!! The solenoids go in the doors, and attach to the locking mechanism via a bar. The solenoid will be fed from an alarm, or a control box for the c/locking, dependant what you have.. The remote fob goes on your keyring.. That's about as specific as I could be, as until you offer the gear into place its a bit different from one application to the next. Is it r-click stuff you have by any chance? If you're not feeding it from an alarm already installed, you'll need to I.d a 12v supply from f/board and a good earth point for the master solenoid
