Simple access security setup for home

That system is about that I need except it's PC independant. It maybe though a more cost effective solution.

Has anymore tried the Keypad and Control Module - SC-20-B ?

The problem with proximity cards is that I wanted to avoid a meeting with the tenants at the start of their stay. I was thinking using a PC with a dedicated connection to the internet and receiving update commands remotely and pushing new codes to the controller (with start dates and expiry dates).

No such thing as "residential grade components" when it comes to access control. There's no simple *and secure* solution either, and placing a keypad outside the protected premise isn't a good idea particularly if it's controlling the entry door. Better to go with a proximity reader and keyfobs. You're still looking at paying between $750 and $1000 though. Make sure the controller is mounted *inside* the protected premise, or you're liable to find some savvy guy that'll be able to bypass the system. In other words, shy away from the "all-in-one" solutions that I know are out there. If it's a "rented" premise, you'd best secure the controller in a well protected (*and inaccessible to the tenants*) area.

This one's $80 if it meets your needs:

The problem with that system is that all you need is a screw-driver, dismount the keypad and short the contacts to the door switch... You're "in", as they say...

But isn't the little control module inside the home that handles all the 12V switching? Look at this diagram:

Yeppers! That looks like like. My other point still holds true though... "If it's a "rented" premise, you'd best secure the controller in a well protected (*and inaccessible to the tenants*) area."
