Having trouble with remote

[gearhead58]

2011 Silverado 5.3 250,000 miles. My remote doesn't work every time. Also when  I open the doors there is no open door alarm. Also no keys left in the ignition switch alarm. I have a intermittent buzzing noise coming from my speakers. The radio volume does not work. No codes are coming up.

Sounds like what I just went through, no chimes and no sounds from radio coming from front door speakers.

Do you have any sound coming from any speakers?

What I did was replace my front door speakers that by the way looked fine, no signs of deterioration or wetness.

After the replacement, everything worked.

Can't offer anything on the remote other than check your remotes battery?
