To unlock the alarm on a 2003 BMW 5 Series, use the remote key fob to press the unlock button. If the remote is unresponsive, you can manually unlock the driver's door with the key, which should deactivate the alarm. If the alarm still does not turn off, inserting the key into the ignition and turning it to the "on" position may also help. If issues persist, consult the owner's manual or seek assistance from a BMW dealer.
