Just an update on this item.
I pulled the door panel and it looks like there is plenty of room below the door handle to mount this keypad. I however would like it above the door handle but I think when drilling I would be too close to the glass (even with it all the way up) so I am going to take out the glass when I drill the holes. If you mounted it below the door handle I think the clearance with your drill bit and door glass would be alright as long as you paid attention. I still need to check the clearance above the door handle to make sure the keypad will clear the glass movement, so we will see on that!
I looked at how the door locks are wired in the 2005 hummer and it does not look like a simple relay package will do the job. Luckily they make something called a databus interface module that is a real slick little gizmo. If you have an alarm or remote start on your Hummer chances are you already have one of these or something similar. Basically this things talks to the onboard computer and tells it to lock and unlock your door, turn on and off the alarm, and a few other things like bypassing the passlock security feature if you need to for remote start.
So this Databus interface, model for 05 Hummer is MULTIDL, is another $70.00 but it looks to be the cats meow, easy to install (5 wires) and will save more time than anything. Plus everything will function as a stock hummer does.
Here's the manufactures website for some info:

And here are some retail suppliers for it:
12VoltShop.com
AutoAlarmPro.com
Another thing to note: this keypad made by Essex you see on there the 5 buttons. I thought they would be similar to the ford buttons but in fact they are basically solid plastic and I believe the activation just comes from the heat of your finger becase they do not move to speak of. Which is good as that is one less thing to wear out, but it does feel a little funny to use at first.
So once I get the Databus interface I will be off and runing, will keep the board posted.
