How do I reset a 2002 bmw 320i immobilizer?

SOURCE: I replace the cover on my key and now my car want

Go to BMW dealership, with all the proof of ownership papers and they will order you the correct key to start your car. You can not mess with their anti theft proofing and expect it to work. Personally I would say that I got a replacement key cut and lost the old one, thinking that the replacement key was enough to get the car working.... that way they won't laugh at you inside the dealership. You broke the RF, located inside the key cover. Now the only way to fix it is through the BMW dealership, and it is not going to be cheap. But then again, you own a BMW, not exactly a car you buy because it is easy on the pocket book. Good luck

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
