ToniTec

ABUS-made cylinders in an alloy chosen for weather

Two ToniTec cylinders appear here, and the interesting property is not security.

Cylinders usually seize before they are attacked

On a north-facing door, a coastal house or a garage side door taking driving rain, corrosion ends more cylinders than any tool does — and the failure is a key snapped off in a lock at seven in the morning.

ToniTec states a Titalium alloy body with an anodized finish, chosen for corrosion resistance. On an exposed door that is a more relevant property than an extra pin stack, and it is not one most listings mention at all.

Made by ABUS

Stated on the listing, which is reassuring on a house brand: the mechanism has a known origin rather than an anonymous one. Keep the code card regardless — it is the only way to reorder keys or matching cylinders years later, and it is the item most likely to be thrown away with the packaging.

The thumbturn version

The 30/30K has a knob inside instead of a keyway, which means the door opens from within without a key. That is the correct choice for most front doors and for any door on an escape route — and it is wrong where glazing or a mailbox puts the knob within reach from outside.

It is also what a smart lock that turns an inside knob requires, such as the SwitchBot Lock Ultra. Those that fit over the key left inside need instead a cylinder with an emergency function, which opens from outside even with a key inserted — which both ToniTec cylinders state.
