MacBook Pro M1 2020 swap insides

First if the company has the proper paperwork to prove ownership of the locked laptop, I would contact Apple or an Apple Authorized Service Provider to see if they can remove the lock.

Otherwise, try a DFU firmware Restore on the locked laptop.

The physical parts swap is risky due to the parts pairing used by Apple. You will definitely need to swap the Lid Angle Sensor and TouchID when you swap Logic Boards since these two items are permanently paired to the Logic Board if you want to be able to close & open the lid to sleep & wake the laptop, and to be able to use fingerprint recognition.

I have no idea if there may be any other surprises, but these are the ones I know about.

You must be extremely careful since there are a lot of very fragile cables & connectors that are easily damaged even when you take extreme care with them.

Of course you will no longer be able to go to Apple with a laptop that has been altered in this way.

Edit: The USB-C port problem may just be due to a damaged I/O Board which is easily replaced. I find they attract liquids....sometimes the contacts can be cleaned as long as the contacts have not been damaged by corrosion or an electrical short.

If you cannot get it unlocked and are not going to pay for any repairs, then it really doesn't hurt to try the swap making sure to swap the TouchID and Lid Angle Sensor if the laptop has one on the Clutch/Hinge of the Display Assembly. Just don't mix up the parts. Probably best to attach a bit of tape or easy to remove sticker on the items. What do you really have to lose at that point except a bit of time?

Hi Thanks, won't attempt changing boards then. When we bough the MacBooks my colleague got one from Apple New York and I got one from Apple UK, when we watered it wasn't amicable so I done had access to any paperwork. I guess I can contact Apple and send what info I have and see if they will unlock

Not sure i it'll work with Apple's Security features, but...
