You cannot change the EFI chip. The ME region is tied to the CPU. Replacing the chip will cause performance issues and crashing.

Even if the chip I've bought is pre programmed ?
Yes. The ME region is tied to the CPU that is on that board.

Best thing here is for your customer to visit an Apple Store with proof of ownership and some ID. As Apple does have a very special tool which they can unlock the hardware password lock.
If on the other hand the system was iCloud locked then you'll need to have them unlock it from 'Find My iPhone' app or if they have a second Mac from within iCloud services 'Find My Mac'
Replacing the EFI is not a good idea for this kind of issue. In the end you'll have messed it up enough other services won't work correctly as it's security key won't be intact any more (ME Region).
