Question 1

I lost all my keys to my 2019 Lincoln MKT. Can you still make a new one on site?

Accepted Answer

Yes, and it's a job we handle at your location. All-keys-lost on the 2019 MKT means the vehicle's security system has no registered fobs left, so we can't just add a key the way we would if you had one working. We access the system through the OBD port with professional Lincoln-compatible tools, clear the existing key memory, and register new fobs from scratch so any lost ones are dead and can't start the car.

On newer smart key systems like this one, the security access step requires the right equipment and a proper handshake with the vehicle's electronics before programming can begin. Once that access is established, the actual key registration is fairly quick. Total on-site time for an all-keys-lost job typically runs somewhere between 60 and 90 minutes depending on how the car responds, and that includes cutting the emergency insert blade, programming, and a full function test. No tow required.

Question 2

Do I have to tow my MKT to the dealer if I have no working keys?

Accepted Answer

No. Dealers will often tell you the car has to come to them, and for some jobs that's genuinely true. For key replacement on the 2019 MKT, it isn't. We bring the tools to you. The security access, key generation, and programming all happen at your vehicle, whether it's in a driveway, a parking lot, or a work site. The dealer route means a tow bill, an appointment, parts on order, and potentially days without your car. We come to you in Ventura and get it handled on the spot.

Question 3

How long does the all-keys-lost replacement actually take?

Accepted Answer

On the 2019 MKT, figure 60 to 90 minutes for the full job. That covers setup, security access through the OBD port, clearing old key data, registering the new fob, cutting the emergency insert blade, and testing everything before I leave. The security access step on this generation requires a timed handshake with the vehicle that you can't rush, but once it clears, the rest moves quickly. I test all five buttons, both door handles, and push-button start before calling it done.

Question 4

My 2019 MKT fob locks and unlocks fine but the car won't start. What's going on?

Accepted Answer

This is a pattern that comes up on these vehicles. The remote functions and the start authorization run through different parts of the system, so a fob can operate the locks just fine while the vehicle still throws a key-not-detected warning on the push-button start.

A few things cause it. Low fob battery is the first thing to check, because the start system's detection range is tighter than the remote entry range. A dying battery can drop below what the start antenna needs while still having enough signal for lock and unlock. Beyond that, if the fob was programmed with the wrong chip generation, you can see exactly this: locks work, start fails, and it may get worse over multiple cycles as the vehicle's security verification digs deeper. A fob that was dropped or has a damaged antenna trace inside can also produce this split behavior. Bring it to me and I'll read what the vehicle is actually seeing before assuming the fob needs to be replaced outright.

Question 5

I bought a replacement fob for my 2019 MKT online. Can I program it myself?

Accepted Answer

No. The 2019 MKT smart key system does not have an owner-accessible self-programming sequence. There's no ignition-turn pattern or button combination that will register a new fob. That type of onboard relearn only exists on older bladed-key systems, not on proximity smart key platforms like this one. The fob you bought still needs to be paired to your vehicle by someone with professional diagnostic equipment. If you already have it, bring it along when you call. As long as it matches the factory spec for this vehicle, I can program the one you have rather than sourcing a new one.
