2004 GMC Yukon keyless remote locking, door chime, radio issue

2004 GMC Yukon

Installed an aftermarket radio and custom LED lights now when I use my keyless remote to lock the truck and shut the door you can still hear the door chime and it's chiming really fast and doesn't stop and eventually the battery drains.

But if you open the door back up and stick the key in the ignition and turn the car on it stops.

If I do not use the keyless remote to lock the car and use the door lock then everything's fine.

When I unlock the car with the keyless remote everything is fine the issue is when I lock it with the keyless remote this is when I have this problem

Any ideas what's going on

Did you use a proper wiring adaptor for the head unit? What wiring changes were done for the led lights?

I don't know. I hired someone that installs lights and radios so unfortunately I don't have the answer, but should that be the best place to start with the wiring adapter?
