Some 2013-2016 Fusion and MKZ vehicles may not have a valid 5 digit key code stored in the Ford key code retrieval system. If both keys are lost and the original selling dealer does not have the key code on file, a new lock set may be needed. For Fusion IKT (non push-button start) use lock set ES7Z-5422050-A, Fusion push-button start use lock set ES7Z-5422050-B, and for Lincoln MKZ use lock set DP5Z-5422050-A. Kits include pre-cut keys. The push-button start kits come with back-up key blades, but do not include passive key remotes which will need to be ordered separately. Rotunda, the Technical Assistance Center, or the Customer Relations Center will not have key code information.
