| I've got a different spyball model to you so I dont know how much of this will be relevant.
Does it have an LED ,and if so is it flashing?,mine has a code number and you can use this code number by counting the flashes of the LED and using the key on/off as a break between the digits.
In mine you have to press the remote key TWICE if the alarm has sounded or if its hibernating.
Sometimes when its in sleep mode,I've forgotten its there and turned my ingnition on and left it on for a few seconds,this'll trigger the alarm which I can then disable normally.:P
Good luck.
Failing that you can always just undo the alarm from the electrical system,wont solve your problem but'll get you going. |
