Quel cadenas pour mon vélo en ville ?

Choisissez un cadenas certifié FUB ou SRA . Format U (rigide) ou chaîne en acier trempé d'au moins 13 mm de diamètre. Évitez les câbles enroulés (insuffisants en zone urbaine). Verrouillez le cadre + une roue à un point fixe enterré ou scellé.

Comment choisir la longueur d'arceau ?

Mesurez l'épaisseur de ce que vous voulez fermer (porte, anneau, conteneur) et ajoutez 20-30 mm pour confort de manipulation. Les arceaux courts (15-30 mm) sont plus sûrs (moins prises pour outils) mais moins polyvalents.

Un cadenas à combinaison est-il aussi sûr qu'à clé ?

Pour un usage casier ou stockage non sensible : oui. Pour un usage haute sécurité, préférez la clé : les cadenas à combinaison de bas/milieu de gamme se cassent par étirement. Les modèles haute sécurité à code (Abus 158/65) restent une option valable.

Mon cadenas peut-il rouiller à l'extérieur ?

Les modèles entrée de gamme oui, surtout en bord de mer ou cycle gel/dégel. Privilégiez les cadenas en acier inox ou avec traitement anti-corrosion (Abus Granit, Master Lock M40).

Combien de cadenas ouvrant avec la même clé peut-on commander ?

Sur la majorité des modèles haut de gamme, vous pouvez commander des cadenas s'entrouvrants (KA - Keyed Alike), pratique pour gérer plusieurs accès avec une seule clé. Précisez à la commande : nous fournissons le set assorti.

Choosing a padlock for the right use

A padlock is chosen on three criteria: the use (dry indoor, exposed outdoor, bike in town, transport), the shackle (length and diameter), and the locking method (key, combination, smart).

Bike / scooter in town: high-security U-lock or A2P chain, 13-16 mm shackle
Shop roller shutter: hardened padlock, class 4-5, 10-12 mm shackle
Cellar / outbuilding: armoured weatherproof padlock, 8-10 mm shackle
Container / lorry: high-security padlock with shrouded shackle, cut-resistant

Security levels

As with cylinders, high-end padlocks are A2P certified (French certification), with specific classes depending on the use:

Standard	Level	Use
A2P 1★	Basic resistance	Cellar, garden, locker
A2P 2★	Medium resistance	Shop shutter, outbuilding
A2P 3★	High security	Container, garage, scooter
SRA / FUB	Bike-specific	Approved by bike insurers

Frequently asked questions

Which padlock for my bike in town?

Choose a FUB or SRA certified lock: a U-lock (rigid) or a hardened steel chain at least 13 mm in diameter. Avoid coiled cables (not enough in urban areas). Lock the frame + one wheel to a fixed point that is buried or anchored.

How do I choose the shackle length?

Measure the thickness of what you want to lock (door, ring, container) and add 20-30 mm for ease of handling. Short shackles (15-30 mm) are more secure (less room for tools) but less versatile.

Is a combination padlock as secure as a keyed one?

For a locker or non-sensitive storage: yes. For high-security use, choose a key: low and mid-range combination padlocks can be broken by pulling them apart. High-security combination models (Abus 158/65) remain a valid option.

Can my padlock rust outdoors?

Entry-level models can, especially by the sea or with freeze/thaw cycles. Choose stainless steel padlocks or ones with an anti-corrosion treatment (Abus Granit, Master Lock M40).

How many padlocks opening with the same key can I order?

On most high-end models, you can order keyed alike padlocks (KA), handy for managing several access points with a single key. Just say so when ordering: we supply the matching set.
