Just a thought - do you have the new motion sensing keyfobs?

No still the original ones

Just been Googling this and wanted to leave a reply as I have exactly the same issue. 2019 Focus Titanium - keyless entry originally worked on all doors and but recently it's only the driver's door.

Not taken it to the dealership yet and it's not a major issue but it's been interesting to read of your similar experience.

ive got a 2019 focus Vignale im having problems with door handle lock sensors only the drivers door only works the other three doors handle lock sensor don't work took it to a ford dealer this morning they plugged it in and said there is not a problem and they said they didn't even know you could lock the doors with using all four door handles 

Hi Dave,

Had the same thing happen to my 2019 Titanium and eventually sussed out how to sort it.

It seems to be to do with "double-locking". When locking your car using the thumb sensor on the driver's door handle, if you tap it twice in quick succession it toggles the double locking. I found when I double tapped it, keyless entry was now possible on all doors again. Don't know if this is intentional or a glitch but it certainly got mine working again.

The water and doorlocks thing is weird but demonstrates how easy it is for the signal to be detected

I've just bought a couple of Faraday shield pouches for keys - work really well - car does not detect key even when sitting in driver's seat

Got mine here:

Funny l thought the keys went dead after 40 secs of not being moved, so they can’t be detected!

This is a battery saving device. I get this when car has been left for a day or two. Once driven for a couple of days, locks work ok. will open using remote key.
