CAS has 10 keys, can't add #11 that I already bought.

starfox5194 · 09-20-2022, 11:29 PM

2007 e90 335xi - located in CT, USA.

Long story short - I spent $400 on a comfort access key that I can't use because my CAS already has 10 keys in it - Verified with ISTA.

What are my options here? Do I need to buy a new CAS? Can I code it myself? Could I disassemble my CAS and manually delete the keys from the EEPROM?

Do I have to go to the dealer? Any idea how much it will cost?

I don't want to get a DME + CAS + KEYset. I already have MHD on this VIN.

Can someone with more knowledge let me know what options are out there in 2022? Thanks.
