The Digital Dawg Pound has a created a RFID Front Door Lock that uses inexpensive off the shelf electronics. There is a full listing of all the parts required on their site.
“The project works as follows: When a card is placed in front of the RFID reader it outputs a TTL serial signal representing the card’s unique ID. This is sent to the ‘TTL serial to Ethernet server’ module, which converts the serial data stream from the reader into TCP packets which are forwarded to a specified IP address / port. A custom C# application is listening on the specified port for a tag ID’s and once received will check if they are valid, and if so signal the NET-IOM to turn on a relay wait 2 seconds then turn it off again. The relay is connected to a buzzer, and electronic strike which is mounted on the door frame, and when powered allows the door to be pushed open.”

[…] You may remember an RFID project that was featured here last year by The Digital Dawg Pound. Nick has come up with a new and improved RFID Door Entry System. Video after the jump. “I decided to try and improve the reliability and responsiveness of my previous RFID front door project (based around a client / server design), by re-implementing it using the Parallax BASIC Stamp 2e, and the 13.5MHz APSX RW-210 RFID reader as a standalone device. I was also looking to gain some practical experience with BASIC Stamp programming. […]

You can also just buy one too.
The Mykey 2300 and Mykey 4000r are two that utilize RFID.
I have the 2300 installed at my house.
Got it from http://www.cydus-solutions.com
