Titan T-3003 aftermarket alarm

Just purchased a 94 Toyota Camry with a Titan T-3003 alarm system. I have a 2 button remote and need directions on how to program it.  The system arms and disarms properly when turning the ignition to on and pressing the reset switch on the kick panel, so I know the system is operational. From what I can find on the Internet (have done laborous searches) the Titan system is same / similar as Apache, Shark, Patroit, Federal systems or at least all use the same type(302Mhz) keyless remote. I realize this is a rather old system but any help or info would be greatly appreciated. TIA

Forget this post -I have figured it out.  The Titan Remote I purchase on Ebay  was not scratch coded correctly. Fortunately I still had the old non functioning remote.  After talking with a knowledgeable tech and gaining some understanding I was able to recode(scratch and solder circuits) the Ebay remote using the old non functioning remote as a guide. I also was able to decipher the correct code using the label  on the Intergrated circuit. Remote now arms and disarms the alarm system.
