I'm installing magnetic child locks on all the cabinets and drawers in the house to keep my kid out of things. I've been using the Safety 1st brand locks and have been happy with them, but the kits really don't come with enough keys and it seems like there's never one around when you need to get into a drawer. So I ordered some magnets from ebay and designed some housings to make my own keys.
Each key requires two 25mm x 2mm neodymium magnets
Thanks to the rare earth magnets, these keys are actually a little stronger and seem to work better than the originals. They also double as excellent fridge magnets :)
Note: I've only tested these keys with the Safety 1st locks, but these keys should work with any brand of lock with a similar design, just make sure the polarity of your magnets matches the ones on your original key.

Align your magnets
You'll need to check to make sure that the polarity on your magnets is aligned the right way to operate your locks. The easiest way to do this is to make sure that the bottom of your original key and the bottom of your new key repel each other. If the magnets try to stick together then you'll need to flip the magnets in your new key around 180*

Glue in the magnets
Put a few drops of superglue around the base of the key to make sure the magnets won't rattle around inside once the key is glued together. Then drop in the magnets in place making sure to keep the magnets oriented the right way.

Glue your key together
Now that your magnets are oriented the right way, it's time to glue the two halves of your key together. Run a thin bead of glue around the rim of the key base, and also put a drop of glue into each hole in the top of the key. Then line the holes up with the pins in the base of the key and press the two halves together. Hold the key together for 15-30 seconds to give the glue time to set.
