Simply put, a keyway is a slot in a lock for receiving and guiding the key. Of course, with each specially designed keyway made to make a lock even more secure, the definition gets more complicated with plenty of options. When making a duplicate key for your lock, it is important to understand what type of keyway you have in order to determine whether or not your duplicate key is able to be cut and to ensure you have the right type.
A keyway is a square channel machined into round a steel bar. The channel, or keyway, provides a place for a square piece of metal known as a key to lock a pulleyor sprocket onto the round bar. The square key fits in both the keyway and a square slot machined into the sprocket or gear. Our shaft collars are easy to install and can save time and money, giving you a fix where disassembly might otherwise be required. You'll find flexible couplings in a range of styles and sizes, plus shaft locking devices that can be used as drop-in replacements for keyless bushings. We also carry woodruff keys, universal joints and shaft mounts.
Shape of Key
The shapes vary, but you can generally figure out what type of key you need just by looking at the top of the key, called the head or base. This is the part of the mechanically cut key that you hold in your fingers when trying to lock or unlock a door. Kwikset keys are typically more rounded and have between one to three-hole openings on the head. Schlage keys are usually a bit rougher at the top with a block or edgy look to them.
Engraving
Sometimes, the key will have an engraving on the head. Inside the engravings is a code containing letters and/or number combinations, such as KW1, KW10, 5, 6, 66, 65, and so on. Schlage key types usually have a code such as SC1, 68, or C.
Grooves
Place the key down flat with the head on top and the tip on the left. Flip the key over, and look at the correct side of the key. A Kwikset key will have two grooves or indentations. A Schlage key will have only one groove or indentation. Some keys have grooves that look similar, but the grooves alone don’t mean that the keys are compatible with the keyway.

Shaft Keyway Tolerances
Some keys may appear to be interchangeable with another, but over time will wear down the lock if you keep using them on the wrong keyway. For instance, Weiser keys usually contain engravings such as WR5 or WR3 and can be duplicated using the Kwikset key type. However, Kwikset keys cannot be used in a Weiser lock.
