I interested to know how may keys eveyone got when you purchased you X
I noticed that there are 4 keys listed in the User Manual.
2 Master keys sets
1 Spare key
1 Door and ignition key
When I purchased my X (used) I only received 1 master key...So dose that mean my other keys are out there somewhere.

. I'm thinking I may have to change my ignition to prevent thief.

(Is there anything I can do?)
Also, How much dose BMW charge to cut a new key? I heard that MB charges in the $400 range (per key).
