    lol it looks like this is confusing u 2 as much as it is me. lol

    billy, yep unplugged the alarm a few times, but havent tried locking/unlocking the car manually with the alarm unplugged. i will try that tomorrow morning.

    18 button obc, yes, ive never pressed the code button before, but i will try unplugging it.

    ferret,
    yes, alarm is working as normal, so is the central locking. all normal.

    tested earth at the ews, yep, its working. so is the power from fuse 31.

    not insulted.
    the ews is a small black box behind the glovebox with a large yellow plug.

    Yea, thats the one mate - Just had to make sure as there is a few behind there.

    lol it looks like this is confusing u 2 as much as it is me. lol
    Yep, this one has got me stumped !

    Is this an auto, or a manual ?
    As your car is a '95, it shouldn't have a clutch switch - But do you just want to make sure ?

    Clutch Hall sensor was fitted from Jan 1997 onwards.

    In theory, having swapped all your Dads bits over the car should start, but it doesn't. This suggests either something in the cars wiring is still telling EWS to immobilise or its nothing to do with the immobiliser.

    Leaving option B aside for the moment I wonder if the CL system is only sending a single unlock signal instead of the double. When you unlock the doors either with the remote or with the key do the door pins jump up freely or are they sluggish / stiff?

    You've tried locking & unlocking on the passenger side?

    There is no double unlock signal... the double lock signal is activated by both a lock and unlock signal.
    But going along these lines, maybe disconnecting the ZKE will illiminate any CL issues.

    The first signal is from the door solenoid, the second signal is from the lock itself, hence "double lock". The 3G system activates the CL (1st signal from the solenoid) then adds the second signal itself via the loom. To be unset EWS must also have both of these signals, either from the lock itself or via the 3G alarm, otherwise you could just screwdriver the lock and EWS would unset.

    What about trying all the bits including key from your car in your Dad's car.

    thanks a lot for the help fellas.
    if it stops working for any reason when i put it back together ill let you know but for now all is good.

    It's not technically stealing, as you'll be replacing the bits

    Glad it's sorted. Add the alarm first, then test the car, then add the OBC and test the car.

    Hopefully that way, you'll be able to pin point what is causing the issue.

    I suspect it might be the OBC, as IIRC, you've already had the alarm disconnected.
