1. Insert the key: Put your key into the driver's side door lock.
2. Turn the key: Turn the key to the "unlock" position. You might need to turn it a few times or hold it for a second or two. The alarm should stop sounding.
If the alarm persists after trying this several times:
* Check the car's hood and trunk: Make sure they're completely closed and latched. A slightly ajar hood or trunk can trigger the alarm.
* Check for other triggers: Something might be physically triggering the alarm, such as a broken sensor or a wire shorted. Look for any obvious signs of intrusion or damage.
* Dead Battery: A very low battery can sometimes cause the alarm to act erratically. If possible, try jump-starting the car.
* Check your key: Make sure your key isn't damaged or worn.
If none of these steps work, you might have a malfunctioning alarm system and should take your Sebring to a mechanic or an auto locksmith. They can diagnose and resolve the problem.
