Hi James, thank you for reaching out. A refundable core charge is an additional fee you pay upfront when purchasing a remanufactured automotive part, like the BCM 599-953. In this case, the part costs $316.49, and there is a separate $240.00 core charge. You pay both amounts at purchase, but the $240.00 is refundable once you return your old, used module (the core) in acceptable condition. After the returned core is inspected and approved, the core charge is refunded to you, effectively reducing the total cost. This process encourages recycling and remanufacturing of parts, helping save costs and reduce waste. If you have a 2002-2004 Dodge Dakota, this BCM (time and alarm module) should work effectively for your vehicle.
