I've been asked by my parents, who are currently overseas, to retrieve an item from one of the two safes located in their home. The safe uses a key and a dial combination. I have the keys and combinations to both safes and I'm not sure which one is which. One of the safes uses a three-number combination, the other - a four number combination. The problem is, that neither of the combinations have worked on either safe, so I'm assuming that I'm doing something wrong in using the dials. I'm unable to reach my parents by phone to clarify and the matter is somewhat urgent. Here's a photo of the safe that I need to open:

Is anyone familiar with this type of safe? If so, I have just a few general questions:
1. Does it use a three-number or a four-number combination?
2. Do I start entering the combination by spinning the first number to the left or to the right?
3. Does it use the standard dial procedure - i.e., four turns to the left/right, stopping on the first number; three turns to the right/left, stopping on the second number; two turns to the left/right, stopping on the third number; one turn to the right/left until it clicks open (add one more turn for each sequence in case of a four-number combination)? Or is there some non-standard trick to this particular safe?
4. Do I turn the key only after the dial clicks open (supposedly I'll be able to tell by the sound) or do I have to have it turned somehow while turning the dial?
Please help.
