Alpine 8026 alarm

I have an Alpine 8026 alarm but have no remote controls for it.  I downloaded the manual for what looks like the same alarm, the 8026A, from alpine.  I"m not sure that it uses the same remote, the 8426A, since to program it to the alarm you need to adjust the nine dip switches the remote has, along with the ones from the alarm.  The only problem is that the 8026 alarm that I have has no coding switch and 12dip switches, not nine, like the 8026A.  Any help on which remote will work for it, if not this one, would be very appreciated.

Thanks.
