A drill press chuck key has a way of disappearing when you need it. Many times, it's hidden out of sight in some corner of your shop. You can waste a lot of time looking for it.

Use cloth-backed, double-faced carpet tape to attach a small magnet in a convenient location on your drill press. If the magnet is strong enough it may attach to cast-iron parts without need for the double-faced tape.
