    Alarm/immobiliser installation

    Went to start the car today and lights came on the dash but it didn't crank or do anything at all. Typical syndrome if the immobiliser has kicked in. Problem though is that even when de-immobilised it doesnt start. The aux cooling pump also stops when the key is moved to start.

    Some points to note:
    the set/unset no longer gives a beep
    I can hear the immob clicking when setting/unsetting
    On removal of the main multipoint connector from the immobiliser(there are two), the car starts but once deimmobilised from the key fob
    The fob does not lock the car with the main multipoint connector removed - but the key locks and does a total closure.

    Does this mean that the immobiliser is goosed, or the wiring is faulty somewhere?

    Tried resetting by pressing the two fob keys together etc but this did nothing. Also left the battery off for a few minutes but again no joy.

    Its a scorpion 1118 system

    Thanks for any assistance

    Is it better just to remove it and fit another system? If so how difficult is it and would there be any effect on the insurance?

    Sounds a swine of a job to find and sort out. When did you last change your ignition switch?
    We overlook it so easily but it sorted my starting problem out. That switch has a lot you answer for
    One day I will tackle removing my old cobra alarm and immobiliser that only has one fob.. but there are a lot of wires
    Good luck mate

    changed it for a genuine one about 5 years ago. It starts and runs if i disconnect the immobiliser so it seems to me that the control unit is history.

    Thoughts on these two: (scorpion SA30 and Toad AI606)

    Toad Ai606 everyday. I had one fitted on my mk3 golf and it was brilliant. Others have asked on here the same question and most people go with the Toad.
    That's the one I will have fitted to my Corrado when this one annoys me

    100% recommend toad alarm, fitted them on my last 2 cars and they work brilliant. Nothing flashy just exactly what you need it to do, the Clifford's etc always seem to want to do everything but fail on just working.

    Toad immob arrived last week. Any tips for removal of the old one and installation of this system? Obviously i'll disconnect the battery first then remove the fuse panel before separating the existing system. Soldered joints plus heat shrink ok or should i use the crimped fittings? Actually where the alarm wires are to be joined to an existing wire, what is the neatest way of joining? I really don't like using tape there but it may be the only option unless i remove the pins from the connector block.
    And what is a good place to locate the 'brains' - i think its a bit bulkier than the old Scorpion system which was in the dash.
    Lastly - how much time should it take? 2-3 hours maybe? Thanks

    Swifty? How long did it take you to remove the old one and install the new system? Planning to do this over the weekend, but dont want to leave it half finished!

    I'll be honest, I paid someone I knew to do install it as he was a toad certified fitter but it only took him a few hours. If I were you I'd compare the new wiring with old and you might get away with swapping old for new as they are both doing a similar job it should be same connections. The main unit is behind the centre console tucked away neatly, if you remove the glovebox it should give you plenty of room to manoeuvre.

    I think personally I'd go for duraseal type connections for ease of working behind the dash but soldering would do just fine as well, just make sure soldered joints aren't near any moving parts and you don't set fire to anything whilst soldering. when joining onto existing wires, I'd like to hear others opinions, I have soldered to them before and taped it up neatly but I guess cutting and crimping with a duraseal is probably the correct way to do it.

    Good tip about the location. Its quite a large and slightly heavy unit - well compared to the old unit it is.
