I have something else for the central locking programming. If someone has a factory-installed alarm system, they can program the central locking so that when the car is locked, it honks once, acting as a confirmation signal.
Just add 1024 to it.
'How it's done is explained in the error database!'
I once compiled the coding information for the central heating pump on my website.

Unfortunately, I don't have a DWA, so that won't be useful for me .
