Re- Keying W107 door locks, need advice please

[warmblood58]

Hello All! I have a weird issue with my '84 Mercedes 380Sl. I recently discovered when ordering a new vin matched key that the key would only open my glove box and trunk locks which were original, the key would not operate ignition and door locks so obviously these had been changed at one point. I ordered a new vin matched ignition tumbler so now ignition matches, but still have to deal with the two door locks. My question is, is it possible to get new door tumblers keyed to my vin (I have heard no on this) or can I remove the tumblers and send them out to be adjusted to my keys? Does anyone have any good advice here or has been through this? I do not want to buy new door handles from mercedes (330.00 each!) Thank you!
