I bought a 2024 XF in San Diego around June 2024. The keyless locking/unlocking was always spotty at best and always frustrating. How in 2025 can any car manufacturer install a keyless system that doesn't work??? Finally contacted the dealer and took it in to fix. It came back worse, a lot worse. Originally, the trunk/boot would eventually open after a dozen tries. Not anymore. Nothing. Similarly with the rear door, originally it worked eventually but worse now. The dealer wants me to bring it in again so the mechanic can "take a look at it." They already took a look at it so I'm not interested in trying again. Anyone out there have the same problem? Anyone have a fix ... an actual fix instead of trusting the dealer? Thanks.

 

If your under warranty I would keep on the dealer to fix it. That's what a warranty is for.
Now I would consider using a different dealer if you have no luck with the current one.

Go to another dealer. My 2018 never had that problem

 

disconnect the battery for 20 minutes or more

See what happens
