If I buy the entire kit off eBay ( DME, EWS, Ignition, door lock, trunk lock and KEY). Will it be plug and play? Do I need to send it to BMW or someone who can code it. I own a shop and have a 2002 530i sport left behind by a customer with no key and it will take some time to do the abandonment paperwork on it, in the meantime I would like to be able to move the vehicle around my shop freely. Im contemplating parting it out but I don't know yet, I have about 2400.00 in parts in labor in the vehicle now. Long story about how the customer got the key but we now have a lock box for all keys in the shop. My local dealer told me once I get the paperwork in my name I can just order a key, it takes a long time to get this done because of how the vehicle was left behind. Short question is>>>> What can I do if I have no key and no paperwork.
