Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

Car wouldn't start, had security issue. Had ignition changed out but still getting the same security message.
my wires were not broke, but the chip on the key was worn and did not read the same resistance anymore :( fix under $5!! disconnect your cars battery. use a ohmn meter and read your keys ohmn's one needle on one side of the metal stripe on the the key and the other needle reader on the back(other) side of the key. making sure the needles are ONLY on each side on the little (LITTLE) metal strip. I used a vise to hold my key. see what the ohmn is. Then go to radio shack and get a pack of cheap resistors and twisting them in a line not a side by side and get the same resistance as you did on your key. to verify recheck key and then check the line you made by putting the needle on one end and the the other needle on the other. if you get the same number now GREAT if not redo your line of resistors til you do. now then under your steering wheel column find a wire that is white its REAL skinny it goes all the way up to your key. splice it CAREFULLY! for it holds two wires a yellow one and an orange one they are skinny like a bread tye wire! or a thick thread! carefully for one is the AIR BAG WIRE! check this but I remember its the yellow for the airbag. and you want to splice your line into the orange wire. keeping it in line while you tye it in not side by side and not looped just _______*________*_________ so its like that the * is where two resistors are link together. now tape it with elec tape and your key should now work again! and the security still works too! this worked on my 2000 eldorado cadillac did it 02/2011! hope this helps!

I actually got it to start once, but idk if it was because I hit the reset button at the info center or some other reason. Maybe?

Sometimes,not all the times the car wont crank and a message comes on saying to wait 3 minutes, then it will start.Other times it just starts right up.Sometimes I have to endure the 3 minute procedure 2 or 3 times before it starts.

CAR STARTS BUT WON'T CONTINUE TO RUN

for a couple days it would simply not start at all; no turnover just total silence upon turning key; after triple aaa was called then it simply started back up after sitting about 45 minutes on both occasions; took it to a garage they could not figure it out; took it to the dealership; both places said they could not figure it until the car decided to not start again; a frustrating 2 full days waste of time; however, (knock on wood!), it has been fine ever since like it never happened! i checked everything i could including security system, battery, starter,keys and extra keys,key chip, you name it,etc. it's fine now. weird. turned my life upside down for a couple days.
I have a 325i 1995 the ignition turns over but will not start and theft keep flashing
