Keyed to Differ or Keyed Alike locks?

As standard the CISA Astral S - Euro Double Cylinder 40 - 55 (95mm Polished Brass) is supplied Keyed to Differ which means the lock includes a set of keys that are unique and will only open this lock. If you require multiple locks you can choose to have them all Keyed Alike, meaning that each lock can be opened using the same key. You can view this cylinder keyed alike here.

What is Keyed to Differ?

  • Keyed to Differ is the standard way a lock is supplied.
  • Each lock is opened by its own unique key.
  • Each lock includes a unique set of keys.
  • Covered by our returns policy.

What is Keyed Alike?

Our Keyed Alike Cylinder Packs make it easy to create your own custom cylinder lock and key solution - allowing up to 99 keys to unlock any combination of different-sized cylinder locks.

The possibilities are endless - from having one key per family member unlocking the front door, kitchen and patio doors, right up to large-scale company storage keying options.

  • Each key can open multiple locks - the same key could unlock your house and office.
  • Locks need to be the same brand and number of levers.
  • Keyed Alike locks include one set of keys regardless of how many locks are purchased.
  • Made to order so NOT covered by our returns policy.
