The Blues followed up their opening-day defeat at Coventry with another less than impressive result but asked whether his side's disappointing start had forced him to readjust his promotion goal, Keane - who has previously said anything less will be a failure - said: "No way."
He added: "I could give lots of excuses but we're professionals and have got to do better.
"The positives are that we got a point and kept a clean sheet.
"The players hung in there when they weren't quite at the races.
"We could have got something from the game and had two or three very good chances, so we'll take the point and move on."
Keane felt a point each was a fair result and added: "Leicester probably had the better of the chances.
"We were disappointed with the way we played in the first half.
"It took a while to get going but we were brighter in the second half and a bit more solid and composed.
"In the first half we were very sluggish, though.
"Our passing wasn't sharp enough and the pace and angling of it wasn't right."
Keane made a double substitution after the break and was asked about his side's formation, which started as 4-3-3 but then reverted to 4-4-2.
"We look at that every day in training and can adapt within a game," he said.
"I knew that when we made changes at half-time it wouldn't be a problem.
"It all depends on the players we have available and the opposition.
"The players have got to be able to adapt to whatever we think is right on the day."
Leicester boss Nigel Pearson said: "We were a little bit disappointed that we didn't convert some of our chances.
"It would have been nice to win the game.
"We possibly shaded it, although it was a game of few chances and they put us under a bit of pressure in the second half.
"We were relatively pleased with how we applied ourselves but whether it's a point gained or two lost I'm not sure yet.
"We played some good football, especially in the first half, but in the second they were a bit more positive.
"We've made a decent start but it's not a case of being satisfied because even though we are new to the division there's an air of expectation on us to achieve a place in the play-offs.
"We are one of 10 or 12 sides who will fancy their chances and that illustrates how tough this league is.
"I fully expect us to do well and cause a few surprises."
In a game of very few chances, Ipswich's best efforts came from Lee Martin, Jon Walters, Connor Wickham and Damien Delaney.
Former Ipswich defender Wayne Brown headed just over for the Foxes.
