I'm new to this club and i'm guessing that i am not the only one with this problem. Why the hell does my car not start sometimes when i turn the freakin key! The security light is blazing away, and i'm there ready to buy a new goddamn car.. its done this mutliple times and i'm ready to die!!! Please help me before i get a rice car.. justt kidding.. never!

obviously if the security light is on. in my case the ignition wasn't reading the vats or the sensor or whatever in the key. had to replace the whole ignition on the column due to some wires frayed

I had that same problem. It only occurs in the winter, but it'* easy to do. If you can't start it, just wiggle the shifter back and forth a bit. For some reason, unless it is in ABSOLUTE PARK, then it won't start. I don't know if this will apply to you, but give it a shot.

OMG..that brought back an old memory when i was drivin my 95 SE with my drivers permit. I went to start it and NOTHIN happened..and i looked down and the security light was on. I opened the door and shut it and it turned off. ..then it started up like a champ. Never happened again..good times.

I had/have the same problem on my 92 SSEi....i can go out there and turn the key and nothing will happen...i can turn it off then turn it on again and nothing...but then all of the sudden it will start...outta no where....its like there is a short or somehting....but i noticed that once i got a new battery that it didnt do it anymore....and the only time its done it sence i got a new battery is when i drive for 5 min and have the system going the whole time its like the alternator couldn't keep up.....good luck w/ prob....try putting in a new battery...!

An electrical problem needs a good diagnostic.

It'* possible the resistor in your key is going bad or is dirty. Try a different ignition key.

Also try cleaning your battery cables, harnesses, and terminals.

When you put the key in the ignition, it completes a circuit that tells the car you have a valid key. The car expects a key with a specific value of resistor pellet embedded in it. When the Security light is on and the starter won't crank the engine, it'* telling you that it'* not detecting the right resistance from the little chip in your ignition key, and thinks you're trying to steal the car with a copied key (i.e. one that does not have the right value of resistor pellet in it). (I assume the light stays on for about three minutes before you can try again, right?)

Try cleaning the little contacts on the key, or better yet, try another key (hopefully you have at least two). Ace Hardware stores have a "VATS Interrogator" box that enables them to check which key blank will be the correct one to use (there are about 15 different resistance values used), if you want to have another key made but don't feel like paying dealer price$.

I have had this problem as well, only in winter, and yes the battery had to be replaced because it was weak...haven't had the problem since.

clean the key and in the winter out the key oin the on pos then turn on the head lights for a sec then off and see if that helps me works for me and my friends jeep it charges the hole electrical system
