Is it ok to synchronize a overridden method in a subclass which is not synchronized in parent class?

Question

I have a derived class, and for some reason, I have to make two methods of this class synchronized to prevent them executing at the same time. One of the methods is an overridden method. Parent method is not synchronized.

Is it ok to synchronize the overridden method?

synchronized is not part of the method signature.

So it is okay to synchronize the overridden method.
