Question 1

Do I have to go to the Lincoln dealer to get a replacement key for my 2017 MKZ?

Accepted Answer

No. A qualified mobile locksmith can cut and program a smart fob for your 2017 MKZ on site. The key system on this vehicle is handled by professional diagnostic tools that are standard in the automotive locksmith industry. You do not need a Lincoln service department for this job.

What some dealers tell customers is that luxury vehicles require dealer-only programming. For the 2017 MKZ, that is not accurate. The work is done through the OBD port with the right equipment, and it does not require a dealership interface.

The practical advantage of going mobile is that you're not booking a service appointment, arranging a ride, or waiting in a lounge. The job comes to your driveway or your parking spot near Moorpark College and gets done in one visit.

Question 2

What is a smart key and what does the 2017 MKZ fob actually do?

Accepted Answer

The 2017 MKZ uses an Intelligent Access fob, which is Lincoln's name for proximity keyless entry. You carry the fob, and the car detects it when you're close. Touch the door handle to unlock, press the button on the handle to lock, and start the engine without inserting anything into an ignition cylinder.

The fob has 5 buttons. Beyond lock and unlock, the others handle additional functions built into this configuration. The fob also contains a small mechanical blade that folds out for manual door entry if the battery dies or the system drops signal.

None of that works until the fob is programmed to your specific vehicle. A blank fob with a fresh battery and a correctly cut blade is still just a piece of plastic until it's enrolled. Programming writes the fob's identity into the vehicle security system so the car will recognize it and authorize the engine to run. That step requires a diagnostic tool connected to the OBD port. There is no button sequence or ignition trick on this system.

Question 3

How long does it take to get a replacement key through the Lincoln dealer?

Accepted Answer

Longer than most people expect, and it varies by location and inventory. Owners in forums describe appointment waits stretching past a week, and if the fob has to be ordered it adds more time before the programming visit even happens. The programming sequence itself has a timed component that the system enforces, so the in-store portion alone can run close to an hour.

With EZ Car Keyz, I come to you in Moorpark, and the job is typically done in a single visit under an hour. No appointment backlog, no leaving your car overnight, no arranging alternate transport.

Question 4

My 2017 MKZ touch-unlock on the driver door stopped working but the passenger side is fine. Is the fob the problem?

Accepted Answer

Probably not the fob. If the passenger handle still triggers unlock and the push-button start recognizes the fob normally, the key is doing its job. Touch unlock on these works through a capacitive sensor in each door handle, and those sensors can fail or get flaky independently of each other. Dirt, moisture, or a sensor that's just worn out can kill one handle while the other keeps working fine.

Wipe down the handle area and test again. If it stays isolated to one door, you're looking at a door-side issue, not a key issue.

Question 5

I found a fob online that matches the factory FCC ID on my 2017 MKZ. Can I just swap it in?

Accepted Answer

The fob won't work until it's programmed. Matching the factory FCC ID on the fob is the right starting point, it means the radio hardware is compatible, but the vehicle security system doesn't know that fob exists yet. It has to be enrolled through a diagnostic tool connected to your car.

One thing worth knowing: the dealer part number for these fobs had a supersession, so if you're sourcing a replacement shell or a full fob, double-check that what you're buying corresponds to the current replacement, not the older number that's been discontinued. When you call me, I can confirm which version is correct for your car before anything gets ordered.
