The first Shabbat after Pesach, many bake key-shaped challah.

Meaning

During Pesach, heaven's gates are open. The "key" keeps them open for blessings and parnasah.

Symbolism

Keys to success are in G-d's hands. We ask Him to open His treasuries of grace.

Practice

Some shape the challah as a key, others bake a real key wrapped in foil inside.
