Question 1

I lost all my Lincoln keys. Can you still make a new one?

Accepted Answer

Yes. All-keys-lost on the 2023 Navigator is a job we handle on site. Because this vehicle uses a full Intelligent Access smart key system, there is no ignition cylinder to turn and no onboard add-a-key sequence. Getting new fobs programmed when nothing exists in the system requires professional diagnostic equipment to access the vehicle's security module through the OBD port, clear the lost key records, and enroll the new fobs from scratch. Once that is done, the lost fobs are erased and will not start the vehicle.

The process takes longer than a standard spare-key add because of the security access and enrollment steps involved. Plan for 60 to 90 minutes on site. We come to you in Chula Vista with the tools to do the full job at your vehicle, so there is no tow, no appointment queue, and no waiting on parts to be ordered.

Question 2

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

Accepted Answer

No. The dealer will often tell you towing is the only path, and for them it might be. We come to you. Mobile all-keys-lost service on the 2023 Navigator is a real option. Bring the registration and your ID, and we handle security access, key generation, and programming right in your driveway or parking lot in Millenia. No tow, no service bay, no days-long wait for parts.

Question 3

How long does an all-keys-lost replacement take on the 2023 Navigator?

Accepted Answer

On this generation of Navigator with Intelligent Access, the timing is different from older key-in-ignition platforms that used timed security cycles. Professional diagnostic tools handle the security access step, and actual key enrollment completes in a few minutes once access is granted. The rest of the time is setup, cutting any emergency blade if needed, and full function testing of every fob button and every door handle antenna zone.

Total on-site time for all-keys-lost typically runs 60 to 90 minutes. Compare that to the dealer route: tow fee, service intake, appointment availability, and parts lead time can turn a same-day problem into a multi-day situation.

Question 4

My Navigator shows a key-not-detected warning but the fob battery is new. What else causes that?

Accepted Answer

A few things. First, confirm the replacement battery is actually a CR2450, not a CR2032 or another size that fits loosely. Wrong cell is more common than it sounds and will cause exactly this symptom. Second, check that the battery contact inside the fob is sitting flat and making clean contact. If the fob was pried open instead of properly released, the contact tab can bend slightly and cause an intermittent read even with a good battery.

If the battery and contacts are confirmed good and the warning keeps appearing, the issue moves toward the fob itself or the vehicle's antenna system. Each door handle has an antenna that communicates with the fob, and if one zone is weak or failed, detection becomes inconsistent depending on where you are standing. That is a diagnostic job, not a battery swap, and it is worth having someone test the system properly rather than replacing the fob and guessing.

Question 5

Can I buy a fob online and have you program it, or does it have to come from the dealer?

Accepted Answer

You can buy an aftermarket or third-party fob and have it programmed. It does not have to come from the dealer. What matters is that the fob matches the factory FCC ID on your original and carries the correct radio configuration for this vehicle. Mismatched fobs will fail enrollment no matter how good the equipment is.

The dealer part number and the factory FCC ID are printed on the back of your original fob. Match those, verify the seller is providing a legitimate unit and not a knockoff, and bring it to us. We do the programming. That route typically saves a good chunk compared to buying the fob through the dealership.
