Intermitent Locking/Unlocking weirdness

[Snowfury]

Hi boards,

wondering if anyone has seen anyting like this before.

Started about 2 days ago, my fob wouldn't lock my car. Waited 2-3 mins and it worked fine again. changed the battery in the fob, same issue. Tried the other fob, same issue.

Now noticed that the doors don't auto lock when driving and the internal door lock / unlock buttons don't work on passenger or driver side.

I've checked the 2x 30A fuses in lots 2 and 3 in the engine bay fuse box and they seem to be ok.

The only other thing is i swapped the battery over about a month ago but its been fine until now.

Is there a central locking reset process or do we suspect expensive electrical parts?

Thanks in advance

Is your car battery properly charged and in good serviceable condition? A failing or undercharged battery will cause all sorts of odd glitches.
