The wiring is time consuming, but it's not very difficult so long as you make sure you wire everything securely/correctly.
Ok, it looks like there's a relay for them, though I don't know if it's a readily (like the typical SPDT you always see) available one. I wouldn't wire the lock motors directly to the switches, as you may wind up burning the switches up (or in an extreme case, melting something or starting a fire). If it really comes down to it though, you could wire up a pair of DPDT relays (one for lock, one for unlock), and they'll do basically the same thing.
