RFID electronic door lock

I will move into my new home soon, which is the first flat we own. That is why the idea to DIY a RFID electronic door lock is attractive for me at the 1st glance.
But after reading all pages of the DIY instruction, I feel a bit frustrated, as I donnot know when will I be free to do all such work. Anyway, keep the link in the blog, maybe you are interested in it, or I will finally be free to do it. :-D
