Well, the locks are certainly worth a few pounds, and the door would be worth money to someone interested in getting it. However, you are right in saying that the costs of removal are likely to be about the same as the cost of the door.

I got a safe like that last year, I was the only person prepared and able to collect it.

If the OP was to scrap it, I'd be interested if it was anywhere nearby. Hint, hint.
