Looking for suggestions on what try before replacing the CAS to the tune of $1400 quid at the dealership.

Car: 2011 e90 335i, non-CA

Background and the issue: I recently purchased the car from an independent dealership and it came with just one key. For extra peace of mind I wanted to get another backup key so I ordered a replacement key from my local dealership. 2 days later I picked up the key and I got the yellow crossed-out key warning when it was inserted into the slot. Nothing worked, and I tried various different initiation methods that are written about here and elsewhere online.

I left the car with BMW to figure it out. In the process they replaced the FRM under extended warranty, and ordered another replacement key in case the first one was a dud. It turned out that the second key also was a dud and showed the same crossed-out key symbol as the first.

The diagnosis was that the open key-slots must have been disabled and locked by a locksmith or someone outside the BMW network. Seems strange as the car is a 2-owner car with no apparent history of messing with keys. CAS replacement was the only option from BMWs point of view.

What I've tried so far: The specialist that I use hooked the car up and could see that the working key is in slot #1 of 10. He was unable to modify the status of slots 2-10 which were all disabled. I have also asked BMW for a printout of all the work that has been done on car to see if this gives any insight into why the slots are disabled or if all 10 keys have been issued (highly unlikely I would think)

Questions:
- Has anyone experienced something similar?
- Can the "disabled" slots be enabled again - and if so how and what software is needed?
- Anyone in North Carolina with the required software willing to give this a shot?
- Any other suggestions that doesn't involve $$$$ for a new CAS from BMW?


Thanks in advance for the help.

Thanks gamesfrager.

I've digested both those threads and did contact gcoding a few weeks ago who said he could definitely take a look but it involves ripping out the CAS and posting it to him.

I'm keen to explore more options locally before going down that route.

You're welcome. Good luck with it.

I think you need to give G coding a call.

Taking the CAS Module out is not hard, and if you happen to find someone local which is rare, you will still need to remove the CAS.
I am in Canada, and live really close to USA.
I shipped to him with my KEY, and he returned it in my hand the day after.
he over nights it back to you.

use https://shipnix.com/ for cheaper shipping.

Good luck.

I have a similar problem to the OP. I've got a 2010 335i with CA. All the keys to the car had been lost, so I ordered a new one through my local stealership. I was told that the new key would lock/unlock the car and start it, but the CA features wouldn't work. When i put the new key in the dash, all I get is a Key with the diagonal line through it, and no functionality at all on the key. I checked the battery in the key, and it's good.

I've read numerous posts that say that you can open and close key slots in the CAS module with Tool32. I've tried to use the tool, and I've gotten a few results which, based on my interpretation show that all the key slots are closed. I have yet to successfully open a slot, since the correct argument in Tool32 to do so is still unknown to me.
please help
