Car won't start

[anonymous-user]

I need the wisdom of PH

My E30 has an immobiliser

It has a little fob that I keep on my key ring, when I open up the car the red light flashes rapidly and the immobiliser disengages and I drive on my merry way

Yesterday I put a new stereo in the car, the old one has the same connecters so it was a 5 minute job, except, now the car won't start

I have removed the stereo and left it overnight and I tried again this morning, still nothign

I can't see that I have knocked any wires or pulled anything, could one wire cause this?

Have you got AA cover at home?

If it's a rolling code type of immobiliser then the chances are that the key, and the control unit are now out of sync.

You'll need to find out how to get them to re-sync.

There's sometimes a special procedure for disconnecting the battey with these type of immobilisers.

I didn't disconnect the battery at any point

I have just spoken to a friend who said that disconnecting the battery for an amount of time, may reset the immobiliser, is this a good or a very very bad idea?

That's the point I was trying to make earlier. Until you know how the immobiliser works then how can you know what will happen by disconnecting the battery?

Any chance you can find out what sort of immobiliser it is?

My apologies I mis-understood

I can try yeah, not sure if I have it though, I assuming placing a pic of the immobiliser fob on here would be next to useless?

A quick Friday bump...

I think I have identified the immobiliser as a Toad Powerkey

Does anyone know the sequence to re sync these after the battery has been disconnected?

I have attached a photo of the fob for ID purposes and to prove I'm not a dodgy car thief

Cheers I only have one fob, I tried it anyway but no joy

I think I'll just have to upgrade my AA membership and get them to sort it

It's not a Toad system, but when a similar thing happened on my Alfa the other week, the solution turned out to involve leaving the ignition key in the barrel, turned to the first notch, then removing the cover from the lower half of the dashboard, locating the key transponder, unplugging the leads from it, counting 15-20secs, plugging it back and the engine started immediately.

As I said, it may not be the same system, but the transponder unit was a Bosch part, a yellow plastic box the size of a fag packet, that it's possible BMWs use as well (a mate of mine had an E30 3-series and the electrical system seemed to be almost entirely Bosch parts).

I had a similar problem last week.




Sorted.


Edit: Thumpsnap is broken.

If the above re-syncing procedure doesn't work, removal sounds like the best (or maybe only) option.

I don't think the AA will be able to help, best they'll do is tow the car to someone who will be able to take it out.

If you're not able to remove it yourself you'll have to call a local mobile auto-electrician. I guess you're looking at around an hour's labour.

Or just push your car down the road and say it broke down as you were driving?

I don't think that'll work out the way the OP wants!

I can't see the AA patrol ripping his/her way through the car to find and then remove the immobiliser.

If I was to pay someone to fit a new alarm/immobiliser could I kill 2 birds with one stone?

As long as the two birds were:

1. Remove faulty immobiliser
2. Install new alarm/immobiliser

Then yes! I'm sure there's at least one auto-elec guy nearby who'd be happy to help.

Those were the birds I was thinking of

Cheers for your help I will make some calls

Anyone have any recomendations? If there are PH'ers in the SE London area who do this kind of work I would rather throw money at them than some random
