    $azSubName = $azSub.Name

    #get all the resourcegorups within the subscription
    $RGS = Get-AzResourceGroup

    #loop through each resource group 
    foreach($RG in $RGS) {
    #get the resourcegroup lock details.
        $lck = Get-AzResourceLock -ResourceGroupName $RG.ResourceGroupName -AtScope
        
        #if the lock does not exist, create one
        if ($null -eq $lck)
        {
        Write-Host "$($RG.ResourceGroupName) has no lock"
    
        New-AzResourceLock -resourceGroupName $RG.ResourceGroupName -LockName "$($RG.ResourceGroupName)-lck" -LockLevel CanNotDelete -Force
