My Ride: 2001 BMW 330xi
Question Confirmation that this is a Key issue?

Hey folks,
I just want to make sure that I am reading this correctly.
My 330xi is intermittently deciding not to start: No cranking, all electronics on...
It seems if I turn the key in a certain manner it starts most of the time, but I feel like this is putting pressure/stress on the key/ignition. If I try to just turn the key like normal without pulling it toward me at the same time, it will start less often.

So I got a BMW Scanner 1.4 and put it into live mode on the EWS.
Now I can see that when it doesn't start, it gets to the position three and says either:
  • "Wrong Random Code"
  • "Wrong Password" and "Wrong Random Code"

When it decides to start with no problem, these designations are green.

Can someone confirm for me that this means I need to get a new key?

Here are pictures of what it is telling me:

Do you have spare key and have you tried it? Could also be bad ignition switch. Heard they are easy to change out and not expensive.

Unfortunately, this car only came with one key when I got it.
Thank you, I would like to know more about this... Is it a DIY? Or I should have my mechanic look at it?

Definitely DIY. Should b something on this forum for DIY instructions. Do a search. I've seen a stickie where someone posted a DIY for almost every part on the car.

Pelican Parts has your ignition switch for 59.25. New key is like 200 from dealer. Don't think you can get the key anywhere else. Pretty sure it's one or the other. I've never changed the switch but several people have said its easy. Pelicanparts.com good luck

UltimatePeter, it does look like the key most likely bad. The EWS communication has nothing to do with the ignition switch so I wouldn't bother replacing it. Spend your money on a new key, even if it's non-remote a valet or wallet key. Give the connector to the EWS coil around the ignition a quick check before you do. I've seen a post a while back where the locking tab were broken and it was just barely making contact.

FYI: I got my second OEM key from The BMW Parts Store for $136. Had to (re)program both keys at the same time, but that was easy; check the forums for the exact procedure.

Not sure many of the online suppliers will supply keys anymore?? I was informed by a decent parts guy from a fairly major online BMW parts group that BMW dropped the hammer on online key sales, so not sure this is a viable way to get keys anymore??

Not sure how long ago the other poster was able to get the key via The BMW Parts Store?

You want to check with your local dealer as well - Master key/keyfob part number - 66126955750 (BMW list price is showing $166.29 last I checked, some dealers will sell for as low as $124.72).

Ask if the dealer will match online pricing or give you the BMWCCA discount and you should get the key for $125 range.

Also may be an issue with the antenna/charging coil as well?

That is good news for the community if The BMW Parts Store is selling keys online for a reasonable price.

Please explain what you needed to provide as far as documentation, how you place the order and how long it took to receive your key.

Based upon my conversation with the parts folks at one of my main parts suppliers, it may appear that the BMW Parts Store is not following what BMW had mandated, however, as long as you can get your key, go for it while you can get the keys for a reasonable price.
