How do you disable Mercedes car alarm?

To disable a Mercedes car alarm, you can typically use the key fob to unlock the doors, as this often deactivates the alarm system. If the alarm is still sounding, you can insert the key into the ignition and turn it to the "On" position without starting the engine. In some cases, disconnecting the car battery for a short period may also reset the alarm system. Always refer to your owner's manual for specific instructions related to your model.
