There are luggage lockers at Gare du Nord on Level -1 (one floor down from street level) near the exit for Taxis (Rue de Dunkerque). These baggage lockers are coin operated. Costs depend on size, 4€, 7€, 9.5€ for 48 hours.

There is a security check/metal detector you normally have to pass through to access the baggage storage at Gare du Nord/Gare de Lyon.
