2004 dodge stratus se replaced ignition because key wouldn't come out now it wont start or turn over but lights up


My first thought is your security system, on the dash is there a security lamp that is on or flashing when you try to start? Did old key have a transponder in it, does new key?
My info says after 6 consecutive invalid key attempts, the starter motor system will be disabled. The system goes into lockout. You may be able to over-ride lockout, by leaving the key in the on position for 2.5 hrs, If you try that hook up a battery charger, then proceed with starting or programming. As far as programming key, the 1st procedure is to use oem scanner that can communicate with security system. I don't have oem scanner.
Check applicable trouble codes, see if anything relating to security system? If so, I doubt I can help you?

What about your security system, Is there a security lamp on your dash that lites up or flashes?
If the engine starts and stalls, leave the key in the run position. If the security lamp does not flash, then the passlock system is not at fault, so says my info.

When I try to start car, it won't start and security light blinks. I'v e had to ignition switches put on before and I had a new key made. Car still won,t start.


If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.

Justchanged the steering column in my 1999


The passlock needs to be reprogrammed to the key.
PASSKEY LOCKOUT RESET ALL GM CARS 1999 AND UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key
.
After the last time the vehicle should start.
