oooh, Serpi Star? You're screwed mate. Sorry. I had one on my last car, and I searched high and low for some help with it. I think they got taken over by Laserline (Italy) and stopped production etc.
I could get mine to lock and unlock the car, but the actual alarm was random - would go off when set for no reason, when not set for no reason etc.... So I just used the key and had it in 'valet mode' to effectively switch it off. You're honestly better off without it mate.
When I was buying my car now, I checked with a local Clifford installer who said they'd check the alarm install over to make sure it was up to insurance standards for about an hour's labour. They'd knock that off the price of a new alarm install in the event it WASN'T good enough too. Happily for me it was (and is, it's a Clifford

) so I never had to bother them...
What I'm saying is get a new alarm.... Sorry bud
