2004 Vectra. I'm looking for somewhere to get new key fob for cargo locks.

My slide out will not open or closed. It started when my RV would not start, someone help me and said I would change the starter,which I did but RV would not start on its own, I then change the solenoid, but it still did not start, someone check it and said My ignition cylinder was not working, I have now change that and it starts but my slide out no longer want to open?
Were due i start checking it? They were perfectly fine up too when my RV did not start.

2002 Winnebago...

I seem to lose water pressure in my 2017 Adventurer. Although I don't use a filter, my hose is good, the small filter on my connection is clean, but yet each day the pressure goes down. If I disconnect and reconnect the water hose, the pressure is more normal for awhile and then during the day it gets worse.
Any explanations as to why this is happening?

What kind of satallite do I need for the 2019 vista ve? The receiver box is already in it.
