The TSA ID checker was asking every single person if they had metal in their body because if they did they were forced to go elsewhere.

The new lanes are notoriously slower and TSA has acknowledged this.

Use this info as you need to. But for right now if you have metal in your body the main PreCheck check point near the United check-in area is off limits. There was not posting on how long it would be until the new machines are up and running but it looks like just a week or two more.
