Default E90 Key reprogramming...

Hi there,

I'm new to the work of BMW an have recently bought a BMW e90 early 2008.

I'm a technical engineer by trade, (not cars) and have a decent knowledge of programming.

Anyway, I only have one key for my e90, it's the three button one with the key itself hidden inside the fob.

I was hoping to basically just buy another key off eBay and reprogram it. I have done quite a bit of searching and the general consensus is that it can only be done by dealer...

However, could I not:

Use INPA, DIS/SSS to dump the EEPROM and then use one of the cheap Chinese made key programmers to code a key?

Would the key have to be blank (uncoded) or could I for example code a key that has been already coded to another vehicle?
