There was trouble with the original 315mhz systems usually around shopping centers there was a change to 433mhz on later vehicles, what year is your Disco maybe someone has more info on this

Mine has started acting up in the past week.
The remote doesn't work after the car has been standing overnight. If I unlock the door with the key but leave the door closed I can lock then unlock with the fob. Once I've done this it works until the next morning.
It looks suspiciously like a new source of RF interference has moved into the area.
While searching for a bit of information I found this 433mhz sniffer:
Silicon Chip Online - Cheap-N-Easy 433MHz Sniffer
Allegedly you can make for $25, but the pcb board alone is $20 inc postage. Add to that $8 for a reprint of the article with construction details, $11 for the 433mhz RX module from Jaycar plus the other parts and I'd reckon it is closer to $50-60 to build the unit.
The other bit of kit that looks like it would be good for checking for RF interference is the RF Explorer: Home of RF-Explorer and other Microcontroller projects
In terms of RF gear it's really very cheap, but to diagnose a fob problem $130 is a bit spendy.

Mine is a 1999 td5
I had the battery disconnected for about 4 hours yesterday. This morning the remote unlocked the d2 without any need for a manual unlock first.
It may be a coincidence but seems like something has been reset by the disconnecting the power.
