This is the original from muddymaker. What a great model! @muddymaker: THANK YOU VERY MUCH!!!
I downloaded the model and created a further locking mechanism. By turning the steering wheel you lock / unlock the chest. As for my grandkid Mathilda, I added sideplates instead of skulls her initials "MR".
All the gold pieces I left untouched, although for completeness I add the complete set of individual pars with this post.
The plates with their image I cut in two: base plate and picture, you will find these sorted like for example: 4A-Plate_Ship.stl and 4B-Ship.stl. These are prepared for multicolor print. You can print them as a pair with plate rear facing bottom down and picture on top (pictures are all 0.4mm each). But what I did is to print the picture facing buildplate, then plate on top. The 0.4mm gap I filled with removable support (PVA, Bambu Support PLA-PETG, PETG <which I never tried>. This method leads to impressive effects, like picture in gold silk-PLA, and after 0.4mm the top surface of support is pretty sleet, plane, which makes a nice appearance. I used "Bambu PLA-PETG Support filament" whereas the outcome is great.
The lock is attached to the parts after assembly with two selfthreading screws, 2mm outer, 2.5mm inner screw.
For further instructions I like to refer to the original creater, he described everything better than me. Also his the parts in his download cluster are mostly compatible if not even identical to my files. Big difference is the steering wheel with locking mechanism and bottom and top part of the chest.

Cut the plates in two for more freedom doing multicolor.
