Snap resistance is the property that gets tested in practice · review
Two cylinders that take the same key, with ten keys between them. BASI states the V55 range is tested to EN 1303:2015 and supplied direct from the manufacturer, with an emergency function on both.
The conclusion The cylinder in this hub whose maker states a standard without qualification, and the cheapest way to get one key for two doors.
Two cylinders, one key. That is the product, and for a house with a front door and a back door it removes the most persistent small annoyance in a household.
BASI states the V55 range is tested to EN 1303:2015 — the European standard covering cylinders for locks, which grades durability, key security and attack resistance. That is a manufacturer declaration and this page reports it as one. We are not a testing body, we do not assess conformity, and the listing does not publish the individual grades within the standard.
It is nevertheless the clearest such statement in this hub — the GERCAR MLBL-60P3 also cites EN 1303, but only “on the essential points” and with no certificate — and it is worth something that the maker is prepared to make it.
One key opens both doors, which means one lost key opens both doors. That is the honest shape of the trade. It also means that when you do lose it, both cylinders need replacing rather than one — so keep a spare somewhere other than the house, and keep the code card separately from the keys.
Which suits two doors of similar thickness. A front door and a garage side door are often different, and the pair is then the wrong purchase — measure both before ordering, from the center screw hole to each face.
A house with two doors of the same build, and an owner who is tired of two keys.

It is the European standard for cylinders for locks, and it grades them on durability, key security, attack resistance and related properties. BASI states the range is tested to it. We report that as a manufacturer declaration: this site is not a testing body and does not assess conformity, and the listing does not publish the individual grades.
It is a trade. One key for a front and back door means one key to carry and one key to lose — and if it is lost, both doors need rekeying rather than one. Most households decide the convenience is worth it, and it is worth deciding deliberately rather than by accident.
Only with the code from the card, and only while the manufacturer still supplies that code. Keep the card somewhere safe and separate from the keys, and order the third cylinder sooner rather than later if you know you want it.
