1. Key Fob Not Working:
* Dead Battery: Replace the battery in your key fob. This is the most common cause. Instructions for replacing the battery vary slightly depending on the type of key fob you have, but it generally involves prying open the fob case with a small flathead screwdriver.
* Key Fob Programming: If replacing the battery doesn't work, the key fob might need to be reprogrammed. You'll likely need a dealer or a locksmith with specialized equipment to do this.
2. Security Light Flashing Continuously:
This usually indicates the system is activated and preventing the car from starting. Try these steps:
* Wait: Sometimes, waiting for a few minutes allows the system to reset itself.
* Key in Ignition: Try turning the key to the "on" position (without starting the car) several times. This *sometimes* can help reset the system.
* Spare Key: Try a spare key if you have one. If the spare works, the problem likely lies with your primary key fob or its programming.
3. Aftermarket Alarm System Issues:
If you have an aftermarket alarm system installed, its reset procedure will be different and specific to that system. Check the alarm's manual for instructions.
4. Immobilizer System (Most Likely Culprit):
Your 2004 Sebring likely has a passive anti-theft system (immobilizer) integrated into the ignition system. This system prevents the car from starting if it doesn't recognize the key. If none of the above works, the problem is likely with the immobilizer.
* Professional Help: You'll likely need a mechanic or a locksmith familiar with Chrysler vehicles and their security systems to diagnose and resolve an immobilizer problem. This often involves checking the car's computer system for any fault codes.
Important Note: Avoid any attempts to bypass or disable the security system on your own unless you are highly experienced with car electronics. Incorrect procedures can damage your car's electrical system. Always prioritize getting professional help if you're unsure about any step.
