2001 Cavalier Keyless Entry

I'm hoping someone can help me here.  I have an 01' Chevrolet Cavalier with an aftermarket keyless entry / alarm system.  All I can find is a bank of relays with two black plastic boxes zip tied to them.  All the boxes say is "DEI Model: 555L' and the other box says "Valet Model: 551R".  From what I've been able to find out, this is a remote start system but, I don't have remote start, just and alarm and keyless entry.  I'm not sure what component does what.  Anyhow, if the alarm is set, it will activate for no reason a couple of times a day.  I disconnect the battery a few times for a few minutes and this didn't help.  I also replaced a burned out 30A fuse in the birds nest wiring for the DEI unit.  This did absoulutely nothing.

At this point, I would like advice/instruction/diagrams on how to deactive the alarm system and keep the keyless entry system w/FOB.  If this can't be done, I'd like to eliminate/deactive the alarm and keyless entry and return to OEM - no alarm and plain power locks, no/FOB.

There is two remotes.  I have used both remotes to arm and disarm the car and the problem continues.  No, I purchased this car in 2002 from a dealer, and I called the dealer and he said that this model did not come with an alarm/keyless entry system.  You hear the factory horn when you arm the system and you hear the factory horn when the alarm goes off.
