Ideally, yes, if the key is properly programmed to the car and used correctly, the alarm should not go off when unlocking the Chrysler 300. The alarm is designed to trigger when unauthorized access is detected, not when the car is unlocked with the correct key.
However, there are scenarios where the alarm *might* go off even with the correct key:
* Faulty Alarm System: A malfunctioning alarm system could trigger unexpectedly.
* Low Battery in Key Fob: A weak battery in the key fob can sometimes cause erratic behavior and trigger the alarm.
* Recently Disconnected Battery: If the car's battery was recently disconnected, it might need to re-sync with the alarm system.
* Aftermarket Alarm System: An aftermarket alarm system installed in addition to the factory system might have its own quirks.
If your alarm is consistently going off when you unlock the car with the correct key, there's likely a problem that needs professional attention from a Chrysler mechanic or an automotive electrician.
