The Chiefs were beaten by the Chicago Bears on Sunday and have failed to register a win since an opening day victory over Houston in a run of losses that has Reid questioning the intensity of his side.
Asked whether his team are missing some urgency, Reid said: "I think it can be better."
"We all need to pick it up. You have to raise the level and you have to do it right now, right now. That's how it works when you're 1-4, that's how it works.
“There's a time that your character is going to be tested, right. So, there are not a lot of people that are patting you on the back and saying how good you're doing.
One man who won’t be helping Kansas this season is Jamaal Charles.
The running back left the action against the Bears last week and MRI scans have since confirmed he has torn his anterior cruciate ligament in his right knee, ruling him out for the remainder of the 2015 campaign.
However, Reid insists he has no doubts that Charles has what it takes to recover.
"I talked to him (on Sunday)," Reid said. "He's obviously down, but he's positive about coming back and getting himself back.
“That's where his energy will be directed now – getting through the surgery and getting himself back to where he can play.
“And that's where it should be. He's not a selfish guy, he feels like he let the team down – but that's not the case at all."
