Take it to the BMW car dealer. He can make one or order one. Take your title or some proof you own the car to show him. On some cars the key is programes to work on the car's computer. Have him ck to see why the car is acting that way.

Once I've stopped the enginge(off the Ign by key), it's very very hard to restart again and sometimes totally cannot start again. I've to wait for long long time to restart. Can say cannot restart if


Do the dash lights come on? You might want to check the security system because at times it could be setting the anti theft kill switch, and after waiting a bit it will reset itself.... It could also be a bad ignition switch. Good luck!

Ignition problems. Sometimes the car will start and sometimes it won't even try. I thought maybe holding the gear shifter up will help and sometimes putting it in neutral will work when nothing e


From what you describe it sounds like the shift linkage needs adjustment.Was any work done on the transmission,or did you bottom out recently? I don't think it's electrical.Also don't keep a lot of keys on your ignition key ring this can wear the key slot and also cause the erratic starts.Good luck.

Key goes into ignition with the greatest of ease. Sometimes wont start the car, sometimes will. Do i need a new ignition? Could this be expensive or maybe just something simple wrong? Car is 5 years old....


Could be 2 things first the ignition. 2nd the ignition switch. I would bet on the ignition switch. To access then remove the 3 phillips screw on the bottom of the column cover. If you can turn your key forward push the pin on the ignition housing. Ignition slides out. The ignition switch is on the left side of the column the small black box held in by 2 screws. If new ignition is needed buy one from the dealer or you will end up with different keys for the ignition & doors

Car won't start


Nahh, its not that bad!
Its either your battery who is empty and need to be charged again or its the electronic box who need to be restarted.
Sometimes if the battery gets empty it can give the electronic box wrong signal, therefore it needs a restart, it can only be done at the ww service center. But try first to charge your battery, i think that will get your car to start again. The ticking noise and the non functioning door is because your empty battery.

You can either charge the battery (the best way to do it) or try to ger someone to tow your car to start and then drive for 45-50 minutes, thar will also charge your battery.

Good luck to you

It sounds like your car has an intermittent open current feed problem. Has there been any electrical/component repair or replacement recently? If so, that would be a starting point for diagnosis. Sounds like an ignition switch type problem. If you had an intermittent battery connection, the car would continue to run from the alternator output, but would not cause the warning lights to go through their initial "bulb check" sequence. But if "on" voltage is lost at the ignition switch, or that circuit, it would.
