2010 Lincoln MKZ Remote Head Key Replacement - Fast, Affordable & Professional

A call came in from a guy over in Ramona Highlands. Parking garage, late at night, 10:30 or so. His only key to his 2010 MKZ was gone. Checked every pocket, checked the seat, checked the concrete. Gone. He was already thinking tow truck.

I kept him on the phone. First thing I needed was his VIN. He had no idea where to look. I told him to face the windshield from outside on the driver's side and look at the base of the glass. Seventeen characters. He found it. Then I told him his insurance app on his phone almost certainly had a digital copy of his registration. It did.

That VIN told me exactly what I was dealing with before I touched a single tool. I prepped the right key blank and loaded up the right gear. By the time I pulled into that garage, I was not guessing.

The job itself was all-keys-lost. That means the security system has to be accessed through the OBD port, all previously enrolled keys get wiped, and the new keys are written fresh. There is a timed wait built into that security access sequence, so I let the clock run while I cut both keys on my bench. When the system was ready, I enrolled both remote head keys and walked every function, door by door, trunk release, ignition.

He calmed down somewhere around the point where the doors started locking on command. That moment where somebody goes from full panic to just quietly watching the lights blink, I see it on almost every all-keys-lost job.

He drove home that night. The dealer was closed, and even if they weren't, this would have cost him a tow plus a wait for parts. He called from a parking garage in Ramona Highlands and was back on the road the same night. That's the whole point.
