How easy would it be to crack a Ledger Nano S?

My cold wallet, when I'm out of my place, it travels with me everywhere because I feel it's safer this way as I travel light and take good care of my belongings, also, the ledger is within a key lock protected by a 4 digit pin (different from the ledger's pin, of course).

My question to the community is, if someone where to crack the pin of my key lock (metal built and very robust) how easy would it be to crack the ledger 'spin?

In case this happened though, I keep my 24 words seed split in different places in the cloud (not in a single server) which I could easily retrieve, load the wallet and get the funds out of there to minimize the chances of loosing BTC.
