2001 Chevy Impala

After replacing the radiator the "security passlock" seems to be preventing the engine from starting. Turns over just fine but will not start. I have disconected the battery hoping it would reset eveything but nothing I've tried seems to change the Security lite on the dash or the radio.

last GM I had that happen on it was only a mater of leaving the key in the "on" position for something like 30 min

any result on this ?

after getting the security alarm reset found that the car had a bad cam pos senor. Replaced the easy enough, now I see that it has a bad lower intake gasket.
