Security light on solid, blazer runs
 

Not an urgent issue but ever since i bought my blazer about two years ago the security light has been on solid, the truck has ways ran just fine but im trying to get some of the lights on the dash to go away. I beleive it might have something to do with the radio splice job the previouse owner did to the poor thing, anyone know what i might be able to do to solve the issue?

Nevermind
 

Later that night the blazer decided to start blinking at me... reset the passlock security system with the key trick and the lights been off since then so i guess its all good now aparently
