How to Overcome Peugeot Partner Immobiliser ?

I have a 51 plate Peugeot Partner Van 1.9D. I snapped my key of in the lock. Decided to buy new key and lock set but didn't realise the key had a chip in it.
Peugeot want a lot of money for the repair which is ludicrous considering how much the van is worth.
Is there anyway I can run the van without the immobiliser.
