Car Alarms: Unknown aftermarket security system in a 2008 Toyota Sienna, fcc id number, keyless entry remotes

Question
I just recently purchased a used 2008 Sienna with an aftermarket security system installed.  There was no security system documentation supplied, so I'm unsure as to the manufacturer of the system. The system operates with the Toyota keyless entry remotes and features a small blue led installed in the dash that flashes when the vehicle is locked.  Another feature of the system is that pressing and holding the unlock button on the keyless entry remote triggers the honking horn and flashing lights.  I would like to identify the manufacturer of the system so that I could better understand all of its features - is there a simple way that I can ID the type of system installed?

Answer
Go to google and type in - replacement
transmitters for car alarms -.

The links back would lead you to sites
that supplies them, and how to locate it using the
FCC ID number on the remote/fob.

Good luck with the hunt.
