You\'re offerding on a used & unlocked OEMBMW smart key,it has been tested and shown in good working order,the housing shows some wear & tear but no cracks,it works for the push to start button,the case was opened and glued back togeter for the unlocking procedure,you can see the gap between the cases.The emergency key needs to be cut before it can be fully inserted into the remote slot.Please be noted,the BMW dealers won\'t reprogram this remote for you,it can be only programmed by some professional locksmiths,please check with them before buying.This remote isNOTself-programmable,it won\'t work,the self-programming video that you saw on youtube only is only good for the brand new one you order directly from the BMW dealership.Thanks for watching.
