personal recognition system

My stepson has a 2005 PT Cruizer with a stock alarm and an added Identity Personal Recognition System (IPRS) installed.  This device won't allow the car to start unless the remote is pushed.  Well, you guessed it, he has lost the remote and now can't get the car started.  This device was installed by the previous owner, and I can't seem to find anything on Google that would help me bypass it.

Thoughts, ideas?

Thanks in advance!

UPDATE!!  It is only an aftermarket starter relay module that has an antenna on it.  It replaces the factory starter relay and relies on constant voltage applied (unsure which lead) to it.  The owner has a special FOB that when pressed allows the starter to engage for a up to 10-15 seconds. 

All I did was replace it with a factory relay.  However, to start the engine with this relay installed and no FOB, follow these instructions:

Turn the ignition to start and hold in this position for 5 seconds.  Turn off the ignition.  Repeat 7 times.  On the 7th time, the circuit is bypassed and the car will start.

If a mod feels this post is inappropriate, please feel free to edit and remove the above line.  I know security is an issue, but wanted to allow people who search google to find this post.

Thanks for all the suggestions.
