Here is my guide to the dealer fit alarm and immobiliser's...
there were a few different "dealer" option fit alarm and immobiliser options on top of the factory key immobiliser that were fitted from 1994
first is the Scorpion 915 key fob
Now the Scorpion 918Key fob is similar to the 915 but with 2 buttons
There was also the Scorpion 5000 (2 button remote and cat1 certified)Info required as I'm having trouble finding correct details but here is the reset instructions
If it's the original Scorpion 5000 alarm it needs the battery to be reconnected in a set sequence for the alarm to be reset.
1 With battery disconnected turn ignition on
2 connect battery (at this point you should hear the alarm registering power, though not 'going off')
3 turn off ignition
4 press and hold down the set alarm button for 10 seconds (though it will probably set after only 2 or 3 seconds)
that should reset everything but you will have problems if you have been trying all sorts of things and confused the alarm system. If that is the case disconnect from the battery for a while (maybe as much as a few hours) so the alarm unit is discharged of all power before setting as above.
then we have the conlogic 850/950 series made by conlogInstruction manual
