My berlingo ignition key 'chip reader' seems to be failing. It won't recognise the key 9 times out of ten, but if I hold the spare key reversed so the chip is right up against the barrel while I turn the other key, it works every time. It's a high mileage workhorse diseasel van, which is fitted with a scorpion alarm anyway, so If I just rig an ignition live feed to the fuel-off solenoid, and disconnect the dashboard warning lamp and buzzer, is that enough to bypass the immobiliser?
cheers
