Has anyone else had issues resetting 315mhz OEM Keys for E series BMW(specifically PCF7945 and PCF7953)? Ive been in contact with tech support and cannot figure out why all my keys think they are 868mhz after the reset procedure.

I did one yesterday but with 868mhz and all went OK.I guess its not a answer to your question...I dont have one with 315mhz.

Yes, 868 would work fine.

i did an eeprom dump of a reset key and found the bug, Ive reported it to tech support. Very likely when used in conjunction with autohex it would get covered up and never known about. When used with other key making software it throws errors about incorrect key type.

After Manually correcting the dump values the key worked flawlessly.
