crimestopper remote programming

I just bought a used car from a dealer and found out that it had crimestopper RS-1905 FM system installed. The problem is that the dealer did not give me any remote and being an older model remotes are hard to find. I was going to use the optional negative trigger wire from door lock and program the system to start using factory keyless remote. But in order to do the programming I need a Crimestopper remote. Can anyone please guide me if the programming is possible without a CS remote? The second option I was thinking was to buy a new CS system that uses the same wire connectors as my existing unit. Is anyone aware of a model number that uses the same wire harness as RS-1905 FM? Thanks for your help

On the older crimestoppers you can try .. hood open or ground hood wire ignition on valet button 5 times choose option with valet use the brake pedal to make changes Worked 1904dp models may work on yours
