This sounds extremely complicated compared to the somewhat more realistic "throw the jewelry in the toolbox and walk out" or the "unlock a window" approach. The most realistic approach is to lie to the customer... "well, we need to special order a left handed crescent wrench and some frequency grease and also do some mold abatement". This is before we get started with outright insurance fraud and the like.
It could happen, but it sounds a lot more like a hollywood movie plot security threat than a real security threat.
