2016 Lincoln MKZ Key Replacement

2016 MKZ key specs

From 2013, the MKZ uses push-button start and passive entry. Catalogs list the 2013-2016 fob under FCC ID M3N-A2C31243300, a 902 MHz key with an NXP Hitag Pro transponder, and the emergency blade inside is the HU101 profile rather than the older Ford 8-cut. That blade uses a different key blank and cutting setup, so a key from an older Lincoln won't serve as a door key here. Because catalogs show more than one fob style for these years, we match the part number before ordering.

What's specific to the 2016 MKZ

2016 was the final model year of the MKZ Second generation (CD4), before the Second generation (2017 refresh) arrived for 2017. Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2016 Lincoln MKZ matches a 2013.

At roughly 10 years old, a 2016 Lincoln MKZ has usually seen real wear. Fob cases crack, buttons wear through and solder joints loosen at this age, so a new shell or a replacement remote often beats repairing the old one. Many have changed hands more than once, so erasing keys you can't account for is worth doing during the visit.

Key options for the 2016 Lincoln MKZ

• Smart proximity key (push-to-start). Proximity keys bring a security trade-off worth understanding. Because the fob is always listening, thieves with relay equipment can stretch its signal from inside your house to the car in the driveway. Keeping the fob away from exterior walls, or in a signal-blocking pouch, closes that gap, and some fobs offer a sleep mode described in the owner's manual. If a smart key for your 2016 Lincoln MKZ is lost or stolen, programming a replacement is the moment to delete the missing fob from the car's memory. And be wary of used fobs from online sellers: a lot of them are locked to the vehicle they came from and can't be reprogrammed to yours.

How the Lincoln immobilizer works on the MKZ

Every Lincoln from the 2000 model year on uses Ford's Passive Anti-Theft System, PATS, which Ford also markets as SecuriLock. A transponder in the key head, or inside the fob on push-button cars, answers a challenge from the car, and the engine won't run unless that code matches a key stored in memory. The hardware changed in clear steps. The Town Car, Continental and Navigator through 2002, plus the 2002 Blackwood, use a Texas 4C fixed-code chip in a Ford 8-cut key. The 2000-2002 LS used a Texas 4D60 chip, and from 2003 the line moved to Texas 4D63 keys. Remote-head keys, with the lock buttons molded into the key, show up from the 2006 Zephyr on. Intelligent Access with push-button start arrived on the 2009 MKS, using 315 MHz fobs with a Philips ID46 chip and a hidden emergency blade. The 2013 MKZ introduced 902 MHz fobs with NXP Hitag Pro encryption and an HU101 emergency blade, while the MKX, MKS, MKT and Navigator kept the older 315 MHz style for several more years. The 2020 Aviator and Corsair added Phone As A Key, which lets a paired smartphone act as the key.

• Catalogs list the HU101 emergency key, Ford part 164-R7992, for 2013-2016 MKZs.
• Among the Lincolns covered here, the 2013 MKZ is the earliest model catalogued with the HU101 emergency blade.

Programming a 2016 MKZ key

Fobs are registered through the OBD-II port with a programmer, after Ford's security access step, and the HU101 emergency blade is cut to the car's code. With a working fob, a spare is routine. For all-keys-lost, 2015-2016 cars often need an emulator or bypass cable before new fobs can be programmed, and we confirm coverage by VIN before promising a same-visit result.

Spare fobs are routine; all-keys-lost on 2015-2016 cars can need an emulator cable, which we confirm by VIN first.

Lost every key to your MKZ?

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Lincoln MKZ can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. Entry comes before key-making because we need access to the ignition, the OBD-II port and sometimes the documents in the glove box. We take care with weather stripping, door frames and paint, and we confirm the dash VIN matches your registration before going any further.
3. Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
4. Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
5. Erase missing keys and add a spare. A lost key's metal blade can still open your doors even after its chip is erased. If the keys disappeared along with something showing where you live or park, consider rekeying the car's door lock cylinders too. We'll also recommend leaving with two working keys, not one.

Why a spare key pays for itself

• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.
• A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.
• When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2016 Lincoln MKZ we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

MKZ key battery

A fob battery rarely dies all at once. The warning signs build: you have to get closer to the car before the doors respond, the dash shows a key battery or key-not-detected message, or the push-button start only works with the fob held near the button. Inland heat speeds that decline, especially for fobs left in a hot cabin or on the dashboard. Keep a spare replacement at home in a cool drawer, sealed in its original package, and buy from a busy store where stock turns over quickly. A cell that sat on a shelf for years may arrive already partly spent.

How the job works

1. Identify the exact key your MKZ uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Lincoln MKZ keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
2. Verify ownership before any work. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
3. Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
4. Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your MKZ, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.

What affects the price of an MKZ key

• The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your MKZ came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• Factory or aftermarket parts. Factory keys and fobs carry the manufacturer's part number and usually the highest parts cost. Quality aftermarket keys use compatible electronics at a lower price and work well on many vehicles. We tell you which options we trust for your car, and where an aftermarket version has known range or fit issues, we steer you to OEM.
• All keys lost or adding a key. On some vehicles, losing the last key changes the programming entirely, from a quick add-key procedure to a full immobilizer reset or a module read on the bench. That extra labor shows up in the price, and it's the strongest argument for keeping a spare in the house.
• Blade style and cutting. Traditional edge-cut blades are quick to cut. High-security laser-cut blades, with a groove milled into the side, need a specialized machine and more care, and the blanks themselves cost more. If we have to decode a lock to find the cuts, that adds labor as well.

Common Lincoln key problems

• Remote-head keys from roughly 2006 to 2014 crack at the blade root or wear through the button pads. The transponder and remote board can often move into a new shell, but the new blade still has to be cut to your car.
• After a key erase, PATS expects at least two programmed keys, and a car left with one may store code B1213. Ford's owner add-key routine also needs two working keys, so a one-key Lincoln is worth fixing early.
• Inland Empire summer heat drains fob batteries faster. Lincoln fobs from about 2017 on take a CR2450, while many earlier remotes and 315 MHz smart keys use a CR2032, so read the old cell before buying a replacement.

Tips from a mobile locksmith

• Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.
• Never hide a spare key or fob on the outside of the car. Magnetic boxes in wheel wells and under bumpers are the first places a thief checks, and with a proximity fob, a hidden key can let anyone open the doors and drive away. Keep the spare at home or with someone you trust.
• If your vehicle has a proximity key, think about where it sleeps at night. A fob hanging by the front door can sit within range of relay equipment used to open and start cars from outside. A drawer deeper inside the house, a signal-blocking pouch, or the fob's own sleep mode reduces that risk considerably.

Proof of ownership

Making car keys is regulated work in California. Locksmiths are licensed and overseen by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following, and Julian's Locksmith holds company license LCO7891. Verification protects you more than anyone: a locksmith who will make a key for whoever asks will also make one for someone who wants your car. We record your name, the vehicle and its VIN on a work order, and we politely decline jobs where ownership can't be established. You can look up our license at search.dca.ca.gov.
