remote not working

[scrapdaddy]

helo

i have a sirius starmate reciever and my remote quit working or atleast i think it is the remote

in the morning on my way to work the remote will work

but after the reciever has warmed up the remote wont work anymore

and yes i have tried changing the batteries

does anyone else have this problem

any help would be greatly appreciated

p.s i live in canada and im not sure if there is a sirius repair place in town
