Alarm install requires both keys?

I'm getting a Viper 5901 alarm/remote starter installed tomorrow. The installer asked me to bring both keys.

It just occurred to me that I thought the only reason you need both keys is to make an additional key. The alarm is going to have a key bypass kit on it (something comparable to this one), so I'm wondering if both keys are required to program it. Or should I be worried that they're going to make a copy of the key so that they can later get into the car?

Anyone have any experience installing an alarm/remote start in which you needed both keys?

EDIT: From my research, it appears that some cars need 2 keys to program, but I wasn't able to find any info as to whether or not Wranglers require it.

The Wrangler has a protocol for both one and two master key programming.

Some owners only have 1 "master key" but can still program additional non-alarm keys using it per OM.

I've discovered on my factory alarm, I can unlock any door, but on opening the door even with the 'master key' if the alarm is on, it will activate the horn.

The only way my alarm doesn't activate, is to push the 'off/unlock' button before opening the door. The grey keys don't have that, and will activate the alarm even though they will start the Jeep.

It looks like the key by-pass is a transponder. So it will look like a 3rd key to the SKIM. He will need the 2 keys progam the by-pass. Makes sense to me.

Depending on the bypass used it can require one or two. My Viper 5704 used and xpresskit DBALL module and only needed one key to program.
Cool thing about Chrysler keys with lock/unlock buttons is that they will actually arm and disarm aftermarket alarms when installed correctly...
