    $exclusao = "DELETE * FROM chaves ";
    $exclusao .= "WHERE IDchaves = {$chID} ";

    $con_exclusao = mysqli_query($conexao,$exclusao);
    if(!$con_exclusao){
        die("Erro na exclusão do registro");
    }else{
        header("location:listagem.php");
    }
}

?php
  //consulta a tabela chaves
  $cha = "SELECT * FROM chaves ";
  if(isset($_GET["codigo"]) ){
    $id = $_GET["codigo"];
    $cha .="WHERE IDchaves = {$id} ";
 }

  $cons_chaves = mysqli_query($conexao,$cha);
