I am sorry your having this problem

do you have another ignition key to start to start this car ?

Customer: replied 1 year ago.
No I sure don't both keys i have don't work . I bought a crank position sensor was gonna try that
Expert:  ggrote1 replied 1 year ago.

the crank sensor should not be the issue

as the engine would physically crank over and just not fire up if there was a crank sensor problem

with it showing the security and it will not even crank over the odds are the issue is the theft module that reads the key

as the security system is activated this kind of issue will happen
