Immobiliser F@~*ed ....what now?

[father ted]

After fitting an new alternator the other day......i ran motor for about 15 mins ...everthing fine ,stopped and started engine a couple of times .....all okay
...Went to take her for a blat today....but she no go
It looks like the immobilser is tits ,as all circuit that are controlled by it are dead......no matter what reset i carry out...i.e. key fob ,override key ,manual reset via pin code or via disconnecting battery .....
Q:
Am i looking at an Auto-electirician to by-pass the immobiliser/circuit before i can drive her again?

sounds like a good idea. It probably isolates the LT circuit and the starter solenoid so it won't turn over or fire if given a bump start.

Have you powered it down and up again. It might reset it

Oh yes , that an' all - by strange co-incidence that little nugget works well with Airbus aircraft too

i had an imobiliser go once and if you take the fuse out for over 15mins then put back in all residual electrickery is gone and this did work, shot in the dark i know but its free

Hum! Bump-starting an A380 sounds interesting! But the problem is the "bump-stop" ... AKA CFIT! - Streaky

Couldn't find a fuse , but disconnected the battery negative terminal and left her overnight,reconnected and tried again this afternoon....guess what?

RESULT!.......SHE LIVES.....YAAAAAAAAAAY!

Thanks all for your help
she's running sweet as a nut

When I bought my car I had similiar trouble, eventually I ended up pulling out two separate alrams and three different imobilisers - all of 'em not working!.

Ended up with about thirteen feet of wire on the driveway and half a dozen black boxes. Put in one proper one, end of problem.

Glad to see you got yours working.

I pulled a Vecta immobiliser off the Esprit, it had been bypassed and there was no keyfob for it. As it happens I'm probably one of the few people in the UK with a circuit diagram for the Vecta so I plan to get it on the bench and figure out the 'code' for the keyfob, create a new one and reinstall it rather better than it was when I found it. To be fair, the installers had routed an 'easy-to-find' set of wires from the Vecta along the centre tunnel; these were dummies, with the real wiring going out through the floor and along underneath the car - a dodge we used to use too.
