Yes, I would like to know a reason for that too. Maybe once the trial transcripts are released.
We have to also consider that the key
had been touched by the victim before, as it had her lanyard on it. So why wasn't Teresa's DNA on it?
Was it perfectly cleaned by Lenk before he applied Steven's DNA? Maybe. Steven had already been making the rounds in the media claiming he'd been framed though, so it's certainly risky.
Here's an opinion on the key/DNA from someone who works in a forensic DNA lab:

3) There are a variety of scenarios to explain these results. However I would find it odd if she were not found at all. I wonder if it was a mixture. Someone mentioned a mixture and assuming she were present, then deducing out the other person. Per labs I have worked at and I'm pretty sure guidelines used at any good lab, you can't assume a person is present if the item collected is not intimate. For example, you can assume a victim is present on a swab from their body. A t-shirt would be stretching it... so a key definitely not. So it was either single source Avery or a mixture where Avery was the major. Avery being the major would make sense if he were the last person to handle it. It could also be her spare key... he could be a shedder and she is not... etc. More info is definitely needed.
