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?

Yes, provided it's got a conventional injection pump.
Biggest problem is getting the immobilser module of the back of the pump, as 
they can be held on with shear bolts.

So it's basically a magic box hiding the terminal for the solenoid, and 
some carefully applied persuasion is needed to remove it to replace it 
with a bit of wire? I can do that.....

thanks for your reply

Try taking apart the steering column. The sensor often slips. A quick
reorientation is often all that is needed. I can't imagine the sensor is
particular expensive, either. A lot less hassle than attempting to persuade
the immobiliser off an injection pump.

Thanks, Christian
I had considered fixing the spare key inside the steering column 
fairing, beside the sensor, so I'll check the sensor is secure first.
