Thanks for good tips.
As the week in Dallas area was raining a lot, today Sunday I took a can of Acetone and syringe to remove Superglue from my MB door lockers.
Carefully I insert the needle into the locker and inject acetone.
While acetone was working internally I was removing from door handles.
The glue became soft on handle and then carefully I turn the key with drops of acetone on it. Finally I got the key moving on both directions.
I got the door open in about 20 minutes.
After back in home I add a thin lubricant on all lockers to restore the lubricant removed by acetone. All doors works perfectly now.
Thanks for support.
