After the 10 minutes it will start. It used happen once in a while and now it has been happening more frequently. We are told it has someone to do with the security system.

The key has a chip inside that the car must detect before it will let it start. There is a passlock sensor in the ignition lock cylinder that may be failing causing the anti-theft system to not recognize the key chip.
What is this repair going to cost us? And what are our options?
The sensor will cost around $100. Not sure about labor. You may be able to find the fix on YouTube.
