The key that you are using could very well be defective. I would try a second key and see if that is still having intermittent start issues.
Also I would double check the batteries that you installed. Test them with a voltmeter. Do you know what the expiration date was on those batteries. You may be surprised to find out that they are discharged. It can happened.
