Thanks Dave!
I'll try a few of them. Klann also makes a lock-breaker tool for these cars.
Reading at lunch, it appears many have success with using the new key from the new tumbler to take out the old lock 90% of the time. Unfortunatly, our youngest went through a key playing/hiding time and I cannot find a spare key to this car@! So, I will now have 2 new keys.
Dealer won't take an order without verifying my driver's liscense/registration in person. Said MB now makes them sign an affidavid thing. So off to the dealer tomorrow or Saturday.
