      It's possible. The first thing you need is a 24/7 system. These can be pretty rough. You need an extremely weak system running 24/7, with whatever form of wireless yo uwant ( assuming bluetooth).

      Next, you need to hook the computer up to the locks and accesories. There's been alot of work on this one, and your best bet is to use the serial/parallel controlled relay cards.

      Finally you need to create a front-end application, that controls the relays.

      then set up a VNC server on the machine, and a VNC client on your handheld. Voila. Problem fixed.

      Another situation to consider is having the bluetooth check to see if "John's PDA" is in Range every so often (5 seconds?). if it is, unlock doors. Only problem is any joe-schmore can set his Bluetooth SSID to "John's PDA".

          I'm not sure of a wireless link. If there was some way you can make your laptop connect.

          Actually, probably. With some bluetooth RS-232 modules, you can interface to a PIC, and can handle all that. You'll need to know some sweet programming for the PDA though.

              hard wire to the laptop. Dude, punctuation and complete sentences/thoughts. thanks.

              Of course - it's super simple to hook a laptop up to the car's power. There's two ways.
              One is a inverter with the current charging plug you probably have now.
              The other is a DC-DC transformer made for your lapto pto charge in a car.
