I just finished building our locks. I'm working on a post mortem post now that will detail the process, hardware needed and the code so anyone can replicate it. The total cost for our system was around $200. I'll be sure to share it here and on twitter when it's up!
http://www.youtube.com/watch?v=nqdIZYXpnfA At the top level it consists of an arduino, ethernet shield, lock and some basic components. The way I've built it currently allows me to administer the users through WordPress (which we use for our members already). Each member has an RFID code associated with their WordPress account and each time you pass a card over the reader, the arduino sends an HTTP request to the WordPress server and tries to find a match. In this case, the arduino is like a web client but the next step is to make it more into a server so that we can use other devices to open the door like an iPhone, android or even SMS/phone through Twilio. If you want a prebuilt system that allows you to open your door with a mobile phone, I'd check out Lockitron (https://lockitron.com/). They are a YC company. Happy coworking!
