Before you order
How to measure
- Measure from the centre of the fixing-screw hole to each end of the cylinder body.
- Inside is the inside of the door and outside is the outside. Choose the size pair that matches.
- On a thumbturn cylinder the thumbturn goes on the inside. Don't include the thumbturn itself.
- XS and Base key/key cylinders, Euro and oval: it doesn't matter which way round you install them.
- Half cylinders have a 10 mm short side.
- 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.
Illustration. Measured from the centre of the fixing-screw hole.
Questions
Common questions
Which range should I choose?
Each range has its own key system. AP v3 is the top range: its Euro cylinders are BSI Kitemark 3 Star and Sold Secure Diamond. XS Euro cylinders are BSI Kitemark 1 Star. Base cylinders are six-pin brass with anti-pick and anti-drill features. Compare them above, or ask us.
How many keys do I get?
A single AP v3 Euro cylinder comes with 3 all-metal keys, and a single XS or Base Euro cylinder with 5. Rim, half and oval cylinders come with 3. A keyed-alike set includes 3 keys in total on AP v3. On XS and Base it includes 5 if it has a Euro key/key or Euro thumbturn, otherwise 3, however many cylinders it has. Extra keys are sold separately.
Can several doors use one key?
Yes. Build a keyed-alike set in the APECS Builder, with one keyed-alike charge for each cylinder after the first. Each range has its own key, so a set stays within one range.
What is a master suite?
A key for each door, plus a master key that opens the doors you choose. It is for AP v3 and XS Euro doors, and every cylinder is repinned to order. No keys are included: order each door key and at least one master key.
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.
What doors do they fit?
Euro cylinders fit uPVC, aluminium and timber doors with a euro profile lock. An oval cylinder needs a lock made for one, and a rim cylinder a rim nightlatch.
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.
