Mongoose M80 (pre 2009) security system help

Hello all. Having a major crysis and in dire need of some expertise!

I have a mongoose m80 security system which is a pre 2009 model. My remote is worn and had electrical tape over the buttons as the rubber button mold was broken. this has caused an incident where I had left my car for a day or two and noticed when i had to start it the tape was holding the button to disarm down that entire time. now my remote fails to disarm my immobilizer in order to start the car.

so a brief summary of my attempts to fix this problem.

  • replace battery on remote- no change.
  • cannot disarm the system as I'm the cars 3rd-4th owner and have no paperwork anywhere for an override PIN as mentioned in the systems manuals.
  • cannot re-sync the remote as it requires disarming.
  • the siren is dead so i have no idea what "chirping" it may be making to represent a fault.
  • checked all inline fuses on the module and in the vehicles cab and engine bay for good measure.
  • budget to repair is tight as a nuns bum so cant just buy a whole new system until last resort.

Open to suggestions as I'm ripping my hair out and mongoose help is only open Mon-Thur, but having to work makes it pretty useless atm.

You need a friend who is good with electronics. Most of my cars have needed their remotes rebuilt. As long as the chips on your remote are ok, you should be fine.

Have someone who knows electronics look at the keyfob. Most of the time the switches wear out and break. Do you know if the remote is actually working when you press the button (is there an LED?). This is where i would start.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
