My dad died. I can't get into his IPad because I do not have the Passcode. I called and the customer service person said the only way to do it was to reset it in which case I would lose all his pictures which is all I want. HELP!

As noted in the link already provided, Apple can help to gain access to someone’s data stored in iCloud. But for data stored solely on the device, there is nothing they can do to give you access to the data on the device itself.

Without the screen lock passcode, nobody can gain access to a device with data intact. That is by design - the one and the only way to reset a unknown or forgotten screen lock passcode requires the device be erased. There is no alternate mechanism to reset a screen lock passcode. This is a deliberate design feature of iOS and iPadOS to ensure nobody can gain access to a device, with data intact, without knowing the screen lock passcode.

So if the pictures were not sync’d to iCloud or saved on a hard drive or somewhere, and are only stored on the device then what Apple told you is correct - they cannot do anything to get them from the device. All they can do is instruct you how to erase the device to regain use of it.

If he was syncing the photos to iCloud, after you used the link above to get access to his account, you could reset the iPad, and then download the photos from iCloud.
