Help please electrical faults?

Hi,
Two week ago my discovery 2 power steering pump failed, I replaced it the other day only to find my keyfob no longer opens the car? I unlocked the door with the key and silenced the alarm with the fob.
When I put the key in the ignition the dash flashes and beeps but settles and I can start the engine.
I have a symbol that looks like a battery flashing so I recharged the car battery and replaced the keyfob battery twice but no change.?
The car drives but no other doors will unlock either with keyfob or by the rockers with on the dashboard and have also just discovered the indicators/ hazards not working?
Any ideas please

Alan
Moved from general forums as advised

Quick update mate checked it over and the fog lights, rear wiper also not working but when plugged into computers apparently it says the lights are?

see this https://www.landyzone.co.uk/land-rover/flashing-light.226476/ for more info search "crossed B" in the forum's search facility

Thanks for that mate will try look later, bit of a pain with not being able to open doors lol

Quick update,

Removed the interior fuse box last week and although not wet it obviously had been, we had really heavy flash floods when I was replacing the power steering pumps.
I split the fuse box case and there was corrosion on lower part of circuit board.
Replacement fitted, everything working as should again.
