All you need to do is to flip the cam washer over. There are two in package to provide ninety degree or one hundred eighty degree operation.
Local and near by Home depot or Lowes; standard item
Yes. If you can see the 5 digit number on the key in the package you can match them. However, If you can't see it you could buy one and take it to a locksmith for them to match the lock cylinder to your current key.
The installation instructions clearly state that a 3/4 inch drill bit is needed (to drill a 3/4 inch diameter hole). I used a 1/16 inch diameter drill to locate the hole, followed by a 3/4 inch spade bit. Drill half-way through the panel, and finish the hole from the other side to prevent tearout around the hole. You will need a backing block to keep the spade bit from wobbling or chattering.
The first part of this should help you: Go to the Home Depot area where you find these cam lock sets and take the first one you see off the wall peg that they are displayed on and then look on the package for a tiny white label that reads: KEY NO. KEY NO. XXXXX 12345 or another set of numbers, now with that one in your hand remove one after another until you find a match! In the event that you can't find a match for the one in your hand, put that one down and start looking for a match with the next one and you will eventually find a match. Finally, replace the locksets that you are not going to purchase on the peg before you leave, thanks! Enjoy your keyed alike cabinet/drawer locks!
You need to find out the thickness of the wood that the dime sized hole is drilled in, so take a ruler or tape measure and measure along the edge of the drawer or door next to the hole but sometimes there is a lip and in that case, measure at the inside of the hole where the lockset will fit. Sometimes it's easier to do this by taking something like a pencil and holding a finger over the hole on the back/inside and feel that the pencil is flush with the back and with your other hand holding the pencil, hold your thumbnail flush with the outside face of the drawer/door, at the same time pinching your thumb and forefinger firmly on the pencil, then without moving your thumb on the pencil, measure from your thumbnail to the tip of the pencil with your ruler or tape measure. Now write that down and take it to Home Depot and ask for the correct "Chrome Drawer and Cabinet Keyed Cam Lock" that you'll need.
You may need to install barrel bolts on the top and bottom of the door that is opposite the lock door.
Yes, I used mine in a mailbox outdoor.
In my experience, you need to search for ones with the same key number from the store stock. You may be able to special order that.
