Help!

Hi everyone I am in desperate need of help! I lost the keys to my 2004 bmw 545i and have had the hardest time getting a key to work. I went to bmw and ordered a key per my vin # it works on the doors and trunk and glove box but doesn’t fit in the ignition. I found out that the ignition cylinder was not original and the cas had also been changed. So I was told I had a mismatched security system. I found a mobile locksmith and asked him if he could cut and program a key to the donor CAS in my car he said he could, came out and cut a key and still nothing! It does turn over and cranks but does not start. I was then told that key needs to be programmed to the immobilizer system. I’ve spent so much money on keys that do not work. Can anyone tell me what I need to do now or if I can even have this key programmed to the immobilizer system? Thanks in advance

Let an official BMW service fix it for you. No it won't be cheap but yes it will be done correctly. Watch your golden key next time.

I would also suggest get a second golden key and keep it in your safe at home. Just in case. Good Luck.
