Just a quick question. I traded in a 2003 GMC Yukon, When I would push the lock button on the remote twice it would beep to let me know it was "armed", I noticed the H3 doesn't "beep" is it suppose too?

I think you have that option. Check your book it has a section on programing your lock features. I think you can also adjust the auto lock when you shift and maybe do something with the flashing of the lights when you arm your alarm. Personally, I like mine sans "beep".

You can set it up to beep once for lock twice for unlock check the manual.

YES !!!

If you check your book you will see that you can choose either audible or silent on the opening and closing with the remote. (i choose audible, that way you know, no guessing "did i do it")

AND

You can choose to open the drivers door only or all the doors (I set mine to drivers door only because its a safer setting) If you choose to open all doors press your button twice fast.

It takes about 31 seconds to do there CUSTOM modifications
