... I need an ignition key anyway so maybe I'll take the $3.20 chance and see what, if anything, I get from the Classic Center.
Hi Graham,
I would do the same, but please let us know how it turns out. It is always nice to find a good price for an essential part.
According to the parts list for the 250/280SL, the ignition key (2-sided master key) p/n is: 000 766 35 06 - but somehow the footnotes make no sense to me (Group 46, Fig. no. 110). Footnote #5 says that this p/n is good for a 250SL
up to chassis #3048 and footnote #8 indicates that the p/n is correct for a 280SL up to chassis # 12689. My guess is that it is a typo and that the the p/n is correct for a late 250SL
from chassis #3048.
Especially since the same parts list shows the p/n 000 462 0332 to be valid for a ignition key blank up to chassis # 2979 as you wrote, and p/n 111 462 0132 for the actual ignition key also up to #2979.
Also when you buy the key from the Classic center could you find out whether they still have the original Neiman D blank? The company is long, long gone and perhaps the price that is quoted on the web could be for a NOS Neiman blank.
