Snap resistance is the property that gets tested in practice · review
ToniTec's TEC440, made by ABUS, in a Titalium alloy with an anodized finish for corrosion resistance. Six reversible keys, an emergency function, and a code card for reordering.
The conclusion The cylinder for weather rather than for attack. Six keys and an anodized body, made by a known manufacturer.
Cylinders are sold on pick resistance and they usually fail for a duller reason: they seize. On a north-facing door, a coastal house, or a garage side door that takes driving rain, corrosion can put a cylinder out of use well before a tool does — and the failure mode is a key snapped off in a lock at seven in the morning.
A Titalium alloy body with an anodized finish, which ToniTec states is chosen for corrosion resistance. On an exposed door that is a more relevant property than an extra pin stack, and in this hub only the thumbturn TEC440 and the Gercar MLBL mention it too.
Present here as on the ABUS D6XNP cylinders in this hub: the lock works from outside with a key left in the inside. It is worth insisting on across every cylinder you buy, because a household without it eventually locks itself out of its own door.
Six reversible keys, one more than the ABUS D6XNP, and a code card for reordering more — or for ordering further cylinders keyed alike, which is the cheapest way to get one key for a front door, a back door and a garage.
Keep the card. It is the only way to reorder years later, and it is the item most likely to be thrown away with the packaging.
An exposed door, and a household that wants a spare key or two more than usual.

An aluminum alloy used by ABUS in place of brass. It is lighter, and the anodized finish resists corrosion well, which matters on a door that faces weather or salt air. It is a material choice rather than a security grade, and no listing here claims otherwise.
On exposed doors, it can put them out of use before any attack does. A cylinder that has seized is a cylinder that gets forced by its own owner with a pair of pliers, and the key snaps in it. On a coastal or north-facing door, corrosion resistance is a more useful specification than pick resistance.
Because keys and keyed-alike cylinders are reordered from the code card years later, and a house brand can stop being stocked. ToniTec states this is made by ABUS, which is reassuring — but the code card is the thing to keep somewhere safe regardless.
