Things You'll Need
Instructions
Search for the arbor. The arbor is a hole that is in the clock that will fit the key. If you find two arbors then you have what is called a striking clock. You will need to repeat all the following steps for both arbors. There are some American clocks that have three arbors. You will need to repeat the following steps for every arbor found.
Insert the key into the arbor and wind it in the proper direction. If you found the arbor in the front then it should turn in a clockwise direction. If you found the arbor in the back then it should turn in a counterclockwise direction. There are exceptions to this rule. If you are unsure of the direction then gently try both. The key will not be able to turn in the wrong direction. If it is the right direction it will be able to turn and it will make a clicking sound.
Repeat step 2 for each arbor. If there are two arbors then the second arbor will usually need to be turned in the opposite direction from the first.
Wind the key in the arbor until it begins to feel tight. At this point you should stop turning it; otherwise you will risk damaging the clock permanently.
Gently remove the key from the arbor.
