Phone as a key danger.

Some update along the line, erased the door access code.

This happened to me also, details here: https://www.f150lightningforum.com/...-your-backup-start-passcode.31723/post-582850

Ignore the people trying to gaslight you into thinking it was something you did or did not do. There absolutely was an update that erased entry codes and backup start passcodes at some point. I do not know which one, and @Ford Motor Company never got back to me with an answer about how this happened, and what the engineers are doing to make sure it does not happen again.

There is a video from McArthur Long Ford about how to get your master code, as long as you have two different fobs.

No update erased factory door codes. Yes, updates have erased customer-set codes.

Check in your glove boxes and document package, it's the size of a credit card

Do you have Walkaway lock enabled?

We got locked out of the Mach-E 2 years ago leaving fobs and phones in it. Used doorcode.

Yes, WAL is enabled and works fine. It wouldn’t be the first time 2 vehicles behave differently!

Please update your Account Details to include the year of your truck. Seems like in 2024 they stopped printing cards with the keycode. But there is a thread here that shows how to recover the master code without going to the dealer.

You can also use the brute force method and actually read the code on the side of the BCM:


Unless your BCM has been replaced, this code will always work as it is uneditable firmware in the BCM. You cannot erase this one with an update.

Very good to know if you didn't buy your truck new and/or don't have the card.
