How to start my van with new keys?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. All of the parts you replaced are great - but you still have to program the keys to work with the vehicle's immobilizer system. Get any and all keys together and seek guidance at a shop with the programming tool or your local dealership for guidance. They can complete the programming for you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
