Hello, what is it doing or not doing? WIll the dash light up when you push the button to on? WIll it just not engage the starter? Does it have blinking red theft lamp or error message saying the key is not detected?

Customer: replied 7 months ago.
Everything lights up normal ... just starter will not engage each and every time. Car has 111k so am thinking starter is issue as has new battery and push button and electronics respond as they should each time is pushed. FOB battery is good and responds without fail.

Yes as long as he antitheft system is working properly it should crank over and start. You can test the starter circuit operation with a voltmeter and verify you have battery voltage on the large direct positive battery cable feed and the smaller solenoid wire at the starter when holding the key in the crank position. If both have battery voltage but no starter engagement the starter has failed. You can remove the starter and have is bench tested before replacement.
