"Hot wiring" to bypass the ignition lock isn't rocket science but it would no doubt contravene OOF rules to go into detail. 

However one of the car's ECUs needs a successful read of the immobiliser chip before it will allow the engint to start.  The immobiliser chip is also contained in the key which, by the sound of it, you don't have.  Getting around that is going to be much more difficult. 

And much less ethical to publish on a public forum.   ;)

You would have to tape the key, or the transponder chip, to the side of the imoblisor transponder to get that part to work. You would have to have a switched ignition live, and a spring loaded "starter" switch.

All very easy to do, however, you would have no security and  I doubt any insurer would be prepared to cover you for theft, and if you didn't tell them and they found out ..........  :(

You would still need to have some kind of switch to turn 12v on and off. Might be easier to fix it, unless you are doing it for style purposes...

Would have thought it would be cheaper to get a barrell & key from a breaker :-?

Bit costly. Don`t know whether the omega barrell is the same, if so, one could be shipped from the UK I imagine
