Breaking into a safe?

[Joshy]

My friend would like to get into his safe at work, the boss takes the key when he does nightshifts, so is there anyway he can get into it? No explosives or anything, it has no codes just one key its fairly large so can't walk out with it.

the key is like this

The simplest way, if he can get hold of the key for a few seconds, is to take an impression of the key using plasticine or tape. Then he can make a duplicate. If not, tell him to look at http://www.paladin-press.com/ . They have some comprehensive books on lock picking.

ok it may be possible for him to make an impression but where would he go to get it cut?

[Steve_TPF]

You don't get it cut as this is inherently suspicious. He would have to transfer the impression to a piece of metal, preferably stainless or chrome-alloy steel, then shape the new key using a small hobby file. Provided the impression is good and the filing has been done carefully it should work. The smaller the key the more difficult it would be.
I would recommend using the plasticine impression as a stamp by applying ink to the raised surfaces. Once he has an inked outline on paper he can scan/photocopy it as many times as he likes. Glue the silhouette to a piece of steel and file accordingly.
Obviously this takes time but once done he could open the safe easily and quickly, whereas picking the lock would take a few minutes each time, even if he was profficient.
AND USE GOOD QUALITY STEEL! If a piece of crappy mild steel or brass breaks off in the lock it wil be obvious that someone has tried to get in and the list of suspects will be extremely short. It may be possible to get a "blank" key of the right type from a locksmith but he will likely be suspicious. And for goodness sake don't show him the impression.

would the key have to be rounded though? so just to confirm, if he can get hold of the key, get plasticine (would blu-tack work?) dab the impression in ink transfer to paper and the rest is self explanatory.

[Steve_TPF]

The part of the key that fits into the lock should be rounded for smoother operation. All edges should be smoothed as well. Blue-tack is probably a bad choice as it would stick to the key and distort the impression on removal. Note that the plasticine would have to have a stiff backing: cardboard or similar, otherwise it will get distorted before he can use it.
It would be advisable to practise the impression/inking process at home before making the real thing, so as to be sure to get a good result. The inking must be done with particular care: a piece of sponge dipped in ink and brushed lightly over the impression would be best if he can't get an ink pad. If the impression is over-inked it will give a smudged print that will not provide an accurate outline.
BTW after impressing the key in the plasticine remove it from the handle end. Otherwise the key end impression will be damaged.
Also remember that only the lock end of the key needs to be impressed. A matchbox filled with plasticine would do, and would provide some protection for the resulting mold. Just don't leave it in a pocket as body heat may cause it to soften.
