2-Way Advanced Remote Start for Hummer H2 - Question

[Pure_Justice]

Hello All,

I have a question about the 2-Way Advanced Remote Start for Hummer H2.

This new item states that it can control up to 2 vehicles that have a FOB. My question: Can 2 of these work with one vehicle?

Reason I ask, is because, like our FOB from the dealership, that come in 2, it would be a good idea to get 2 units now while only paying for one program.

Any help would greatly appreciated.

Here is the GM Part Number: 19171129


Thanks
