If you're not sure what you're looking for there are a few pics in my signature of the unit itself, not where it's installed unfortunately.
Also, I use my keypad all the time, especially going to the gym (4 times a week). I lock everything, including my keys, in the truck when I go in.
One thing I've learned thou is to make sure your personal code or even the factory code for that matter works before you are 50 miles away from home and realize the keypad died (I did not learn this thru experience thankfully).
Before I lock my keys in I always make sure my code works.
