How do you disable factory alarm from 1994 Plymouth voyager van?

To disable the factory alarm on a 1994 Plymouth Voyager, you can try unlocking the driver's side door with the key, as this often resets the alarm system. If that doesn't work, locate the alarm fuse in the fuse box and remove it to disable the alarm temporarily. Additionally, you can disconnect the battery for a few minutes to reset the system. If issues persist, consulting the owner’s manual or a professional may be necessary.
