Glk 250 cdiX204 (2012). All key lost! I programmed KeylessGo but work as a ordinary key. I used 41 rom, key CGDI Keyless. Does anyone know what the problem is?
Answer:
What keyless key you are using?
The old type keyless key may not work.
Have you tried lock/unlock door by key ?
If also not work, check key frequency.
Question: how can i know if the key is old or new type?
Answer: For this EIS use ROM57 key or china BE.
I used china CGDI keylesGo key but available in menu only 41 or 51 rom, i used 41(keylesgo)
Answer: The new keyless MB key with ROM41 should work.
Your EIS is 212 type,
I have done several W212 keyless.
check the frequency, 315MHz or 433MHz.
As I said there are many keyless MB key.
And CGDI also has old type which may not work in W204 212.
