Understanding Lock Keying Options
When you’re replacing door locks, the manufacturer may offer customizable keying options that let you purchase locks keyed to operate with the same key or locks keyed to require separate keys. We’ll explain keyed alike and keyed different locks as well as some variations. The ordering process may differ depending on the lock, but understanding the terms helps you know what options to choose to get the right locks for your home.
Lock Keying Types
To understand how different keying options work, it’s helpful to know the basics of how a key operates a mechanical lock. In general terms, a lock cylinder contains a series of pins of different lengths. In the locked position, the pins keep the cylinder from turning. When you insert the correct key into the lock, the specific shape of the key allows the pins to fall into an orientation that frees the cylinder to turn, unlocking the lock.
Keyed Different
Order keyed different locks if you’re buying multiple locks of the same type and you want them to all have unique keys. Keyed different locks have pin orientations or combinations that differ from lock to lock. Since the pin combination is specific to each lock, each lock requires a key with a different shape.
Keyed different locks reduce the number of locks you need to replace if you lose a key. They’re a common security measure on private property or in an office setting where some areas are restricted.
Keyed Alike
Order your door locks keyed alike if you want multiple locks of the same model to work with one key or duplicates of that key. Keyed alike locks share the same pin orientation or combination, so the same key allows the pins to fall correctly and unlock the lock.
If you have all door locksets keyed alike on your home, you only have to keep up with one key to be able to open any lockset. If you have several storage areas on a property, keyed alike locks allow quicker and easier access.
Keyed Alike With Other Line Items
Ordering locks keyed alike with other line items lets you purchase multiple lock types set to work with the same key. For example, if you’re ordering entry door knobs and deadbolts, this option lets you order them keyed alike so a single key unlocks your entry doors.
Keyed to Specific
Keyed to specific is a keying option available with some manufacturers. This keying operates like keyed alike lots. The difference is you’re ordering new locks using a code that allows them to work with a key for an existing lock. This option gives you new locks set to operate with a specific key you have already.
Other Keying Options
Not all locks offer an option for choosing a keying type at purchase. In most cases, if you purchase several locks without this option, each works with a unique key. However, you can still get multiple locks set to a single key, whether you’re replacing all the locks on your property or just replacing a few:
- Some locks have a feature that allows you to rekey them to a specific key yourself.
- You can get locks professionally rekeyed.
