XS Euro cylinders have sacrificial cuts and are designed to resist

  • Picking
  • Bumping

    The cylinders

    XS 1-star cylinders

    Every XS 1-star cylinder uses the same key, so you can mix them in one keyed-alike set. Choose a cylinder to pick its size and finish.

    Ratings apply to the Euro cylinders named. On a thumbturn cylinder, the thumbturn goes on the inside of the door.

    How to measure

    1. Measure from the centre of the fixing-screw hole to each end of the cylinder body.
    2. Inside is the inside of the door and outside is the outside. Choose the size pair that matches.
    3. On a thumbturn cylinder the thumbturn goes on the inside. Don't include the thumbturn itself.
    4. XS key/key cylinders: it doesn't matter which way round you install them.
    5. Half cylinders have a 10 mm short side.
    6. Rim cylinders: check the fit against your existing rim cylinder or nightlatch.
    7. Not sure? Send us a photo of your cylinder on WhatsApp and we'll help.

    Thumbturn cylinders: the thumbturn must go on the inside of the door. The key side goes outside.

    Key/key cylinder A key on both sides.
    Thumbturn cylinder Thumbturn inside, key outside. Measure to the end of the body, not the thumbturn.
    Half cylinder Key outside. The short side is 10 mm.
    Oval key/key cylinder A key on both sides.
    Oval thumbturn cylinder Thumbturn inside, key outside.

    Illustration. Measured from the centre of the fixing-screw hole.

    Questions

    XS 1-star questions

    How many keys do I get?

    A single XS Euro cylinder comes with 5 keys. XS rim and half cylinders come with 3. A keyed-alike set includes 5 keys in total, however many cylinders it has. Extra keys are 1 key per purchase.

    Can several doors use one key?

    Yes. Build a keyed-alike set in the APECS Builder: XS Euro, thumbturn, half and rim cylinders can all share one XS key. There's one keyed-alike charge for each cylinder after the first.

    What is a master suite?

    A key for each door, plus a master key that opens the doors you choose. On XS it's for Euro doors: key/key and thumbturn. Every cylinder is repinned to order. No keys are included: order each door key and at least one master key.

    What doors do they fit?

    Euro cylinders fit uPVC, aluminium and timber doors with a euro profile lock. A rim cylinder needs a rim nightlatch.

    Can I order a key for a cylinder I already have?

    Yes. In the APECS Builder choose Extra keys, then "A cylinder I already have", and add the key code from your key card so we can cut the key.

    How is it supplied?

    Supplied to order from APECS. Availability is checked before fulfilment. Keyed-alike and master-suite cylinders are custom-built to your specification. Please review the applicable returns terms before purchase.
