Ok, before everyone shouts at me, I've read all the posts about laguna immobilisers just about everywhere on the internet and still have no clue.
Situation is this:
Laguna 1999, 3l v6 rti, immobiliser does not release intermittantly, tells me as such and light just flashes on dash.
Tried both keys, changed batteries in them etc.. Can't have lost code, coz sometimes they work. If I can't get either key to work, then i have to take posi lead off battery, ignition then on and leave for 10 mins, ignition off, reconnect battery and all is ok. I can't find any pattern as to when it will work or not, tried location, temperature, different key etc.. Just seems random.
The key is of the radio type, not the infra-red type, so no infra red receiver by the sunroof to get damp etc..
I've taken the immobiliser
out, checked all the terminals etc.. all clean, no corrosion. I haven't got the 4 digit code yet, but don't want to always keep entering it.
I'm now thinking of sending the
away and getting it "doctored" so it will always release, regardless of the key, transponder ring, wiring etc... Any last ideas before I do this?
Read loads of stuff about resetting keys etc.., but why would it work sometimes and not others?
