Car Won't Start/turn Over. Possibly Immobilised, Any Ideas?

[HiEUmungus]

Hey guys.

So my car is not running at the moment, it's at my mate's Ultratune. It won't start/turn over. My mate believes the car has immobilised itself but it doesn't respond to my key. Any ideas on what could be the issue? We're thinking a new key with transponder might need to be made up?

Cheers

so it will not physically turn over or it spins over but does not start?

one is a battery issue the other is transponder.

anything else done the car?

If it doesn't even turn over, it could be a transmission N/P switch if it is an auto, or a clutch switch if it is a 6MT. Assuming it isn't a battery of course..

Hey chris

It physically will not turn over. At first, we thought it was a battery issue but when we put in a new battery, still nothing. All the electrics work though, lights on the dashboard come on, headlights still work.

[HiEUmungus]

Yeah its a 6MT. My mate is suggesting we get a good autoelectrician to look at it. Anyone you guys can recommend in Brisbane?

[sonicii]

This is probably a dumb question.. but you are pressing the clutch when you try to start?

I'm not in brisbane, so I can't make any recommendations for auto electricians. Maybe Chris can.

also the alarm/immoblizer needs to be disabled before car will start even if clutch pushed in. sounds like its not turning off b4 u try n start the car?

I think it actually cranks with the immobiliser, it just doesn't fire.

Immobiliser wont turn on anything except for say radio. Hence when immob, the you can't hear the fuel pump priming as its been cut until immobiliser releases it.

I had the same problem this morning but that is because my key fob battery was dying. My FOB wirelessly disarms when the immob is armed eg; disarming and not starting the car which cause the immob to rearm. Rather than having to press the FOB, it wirelessy disarms while cranking over.

If the fuel pump and speedo etc isnt lighting up than immob/transponder issue.

Yes we depressed th clutch. On Saturday when it first started playing up. I had to open my car manually because the alarm and central locking didnt respond to my key fob. When I opened the door manually, the alarm went off but I couldnt switch it off, because it still wasnt responding to the key fob. I put the key into the ignition and tried to start it. None of the lights on the dash came on and it wouldn't turn over or anything. The only things working were the headlights and the headunit. I tried jump starting OT, still nothing so we don't believe its battery related.

[ka86]

Did you change the battery in the key fob? Sounds like it is not disariming the immobiliser.

[HiEUmungus]

yeah we're gonna get the battery changed tomorrow Zack. I pray to god that's the problem lol

Well its exactly what i said, you have not disabled your immoblizer so car will not start, its the first thing you should have tried, new battery for your key., did u tell ur mechanic the above? if so not a very good mechanic if he didnt immanently think the immoblizer and flat key ...

my 6mt clutch switch sensor failed and the car would not start, turned key and got dash but no engine noise. if this is the case you can remove switch and it will start.

[HiEUmungus]

hey guys. it turns out it was just the batteries in the key fob dying. my mate replaced them and bingo! it was able to disable the immobiliser and the car starts fine thank you to everyone for their input!
