Car Alarms: Remote Starter by Valet, 2006 chevy trailblazer, valet remote starter

Question
Dear Expert,

My question is in relationship to a Valet Remote starter which was installed by the previous owner of my 2006 Chevy Trailblazer recently purchased.  The Chevy dealership did not have a manual for this unit as it was not factory installed. I'm not sure where to find the model number for this unit, looked under the hood and dash area with no success.  

I just have the information off the back of the remote starter control which as follows:

(Off back of remote control fob)
Valet CE 8090
PCC ID # EZSDEI474P
RPN: 474T2 Codes

(Control has four buttons, lock unlock, AUX and a round yellow key with an asterisk in center this key is between the lock and unlock buttons.)

As I stated, I'm looking for a manual, have searched on-line with no success.  Hope you can help or direct me to the proper expert.  Thank you in advance for your kind assistance with my question.

Sincerely, I am
Kathleen O
