Alarm Immobiliser Unit, where is it ?

[davek9]

Don't know if this is the correct forum to post this but mods please feel free to move it neccessary

I bought (Honda dealer 150 miles from where i live) my 06 plate 1.8 Sport at the end of May and when i collected it, just as i was driving away i realised that i had only been given 1 Key. I asked for the other key, was told that it had been mislaid and that a new key would be ordered and would be sent to me.

The programming would be organised locally (FOC of course) so i wasn't concerned (annoyed but not concerned). After 3 phone calls the duplicate key arrived so i arranged with my local dealer to have the key programmed.

Turned up, couldn't be done, possible fault with the laptop thingy they use. Have to come back after machine sent to Honda for Recalibrating.

Got phone call, machine back, pop up , key still can't be programmed, apparently on the laptop, engine management is accessible with the new key but not the immobiliser.

The dealer now thinks the immobiliser unit in my car may be faulty, got to go back this week and leave it for the day, but i am confused. Obviously the existing key works ok, so why should a new one not ?

My other concern is that the Technician (mechanic) said that they had to work out where the immobiliser unit was as they had never "done that on a Civic before"

So does anyone please know where it is so i can point them in the right direction

I thought i'd left all this behind when i sold the Audi

Thanks

hey it is not a "Honda fault" that someone lost the key!

I will check it in the manual for you where the immo is.
It can happen that it is not a smaller box like at older cars, it can be part of the MICU or some "boss-ecu".

so as promised:
it is right next to the ignition switch behind the cover

Hi, many thanks for that i'll drop into the conversation where it is

To be honest i wonder if it's the new key that has a fault, will find out i guess later in the week.

Thanks again

Is that the immobiliser or just a transponder reader that feeds into the ECU?

Also, as the dealer doesn't appear to have done much with keys for new Civics, might it be their ability to program rather than the unit? It seems odd that one key is fine and the new one isn't that's all.

At least it's under warranty. I remember hearing about a Fiat owner loosing the master key for her car and being charged for a new ECU, ignition barrel and drivers door! - About £1500!

Both! the reader ring mounted on a plastic box and in this is the immo.

Does that box do circuit cuts? I would have thought that it just gives the ECU a go/no go code then lets the ECU stop the hot-wiring chav stealing your spaceship! If only electrocution was allowed in the UK...

hey we better stop talking about this topic on an open forum...
I don't want to give ideas, infos for the car thefts

[Skippy]

True

However, I've had a quick look around and it appears to be a rolling-code transponder ECU based immobiliser. I can't think of a reliable way of bypassing one and (I'd like to think) I know what I'm doing with transponders.

Feel free to discuss security on the Golf and Focus!

What electrocuting Chavs? Seems a valid discussion to me

yep, we can discuss it here becuase if thefts want to steal a golf they are not going to look for infos on a Civic forum!
