my car for some reason now won't start. it started fine this morning but now won't also something else different is the security light doesn't turn on anymore and the door keys don't work, any idea's, im guessing it has something to do with the security system (oem)

 

anybody, i get nothing, no door chime, no ignition, no accesories, doesnt turn over, can't ne the battery because its new

 

no headlights or anything either? keep in mind that even a brand new battery can go dead overnight with a big enough parasitic draw. either you have corroded terminals, a broken major ground/hot wire, a dead alternator (running only off battery), or a big fat parasitic draw.

disconnect battery. test voltage with digital multimeter. reconnect battery. test again. get car jumped, test again while running. report back your results.

 

Why do you have a brand new battery? Whatever undiagnosed power draw issue you have that caused you to get a new battery in the first place is probably your problem

 

have someone jump start you...if it starts then it's your battery.

 

Don't rule out the battery, but it may be something else also. I had a new battery that died after a week. Turned out the alternator was bad which killed both batteries, I hadn't bothered to check the alternator since the first battery was so old.

 

Check the terminals. I installed a new battery and I had to whack em a few times before the connection became solid

 

Sounds like its the battery but if its not try to jiggle the shifter around before you try to start the car, I had a similar issue last year and it was due to a bad shifter bushing (the car didnt think it was in park so wouldn't start)

 

 

This has nothing to do with your security system. If nothing works or turns on, then there has to be a problem delivering power. The most obvious solution is to check the battery, as everyone else has stated. Just leaving a dome light on overnight can kill your battery.

 

yup it was the battery, and yes i left my dome light on by accident, thanks for the help

 

It happens! We've all done it before.
