Hummer H3 2007 upgrade key

Hi. I was wondering if the simple non-electric car key of a Hummer H3 could be upgraded to a keyless entry?

Thank you. Any instructions on the parts and how to change it? I found the remote control in Amazon but can't find a remote controlled lock cylinder.

H3 keys are NOT chipped. You can only program OEM type (can be aftermarket imitations) using a bi-directional scanner or Tech II at the dealer.

Forget that, have an aftermarket remote start installed and use those fobs = longer range + remote start.
