Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
You dont mention if this is factory or aftermarket alarm and if it has the factory immobilizer/antitheft system. If just an alarm system, disabling it wont affect anything else. If it has the antitheft/immoblizer as well, then it will set the immobilizer and prevent the engine from starting.
Cant say I am familiar with that type. I will opt out and see if another expert knows about this type of alarm
