I am pretty sure that my 2002 is having Passlock issues. The car will not turn over but the lights and radio are working properly. The car was working fine the day before. I also notice that the battery and security lights are blinking back and forth after I try to start the car. After researching this issue online, I see that many people are having this problem but what I am not seeing is how to fix (or bypass) the problem. I am looking for steps on how to solve this issue. Thank you.

In situations, where the engine doesn't start, begin with the basics:

. Remove and fully charge/replace the battery, recording any radio codes first. Most auto parts stores will test and charge batteries for free.

. Test all under hood and under dash fuses with a test light or multimeter:

Be thorough, since it will save a lot of time and money.
