Starter button not firing engine

[crankedup5]

Our Mini cooper (2009) developed a fault, start procedure but pressed starter button and nothing, Then it clears itself and all OK. Rinse and repeat a few times so I take it in to our local indie. They diagnose the electronic steering lock as the problem and component needs replacing at £507.
That’s done but now find the electronic cache? unit has failed and so cannot code key to new steering lock, so that’s £367. Stuck now and have to pay nearly £1k for being able to start the car.
Looked up car value at £1350. I really dislike all the worthless electronics on modern cars.
