We got the key out and I left it at my indie. The MB parts guy said the new tumbler will work with my key and they order it with the VIN number.

I thought about the ebay route but didn't want different key for the doors and trunk and the trunk lock needs to be replaced too so I'm going to order that at the same time. I have to turn the key to the left and pull out on the trunk button, then back to center in order for the button to push and open the trunk. Have had it cleaned but still having problems so as long as I have to replace the ignition I'll have that replaced as well.

My indie can install both.

I'm not putting the key in the ignition again until they replace it.

Can they check the tumbler with my key when I pick it up? I don't think it's been re-keyed and the parts guy said if it had they would order the new key ID as it would be in their system by VIN. I just want to make sure before I get it back that it will work.
