The main types of keys
| Type | Typical use | Can be copied |
|---|---|---|
| Flat key (pin tumbler) | Front doors, euro profile cylinders | Yes, at the workshop |
| Lever key (solid shank) | Older doors, cellars, outbuildings | Yes, at the workshop |
| Tubular / push key | Metal roller shutters, anti-theft locks, vending machines | Yes, depending on the model |
| Patented / security key | High-security locks (BKS, DOM, Vachette…) | With the key registration card |
| Multipoint lock key | Security doors (3-, 5- or 7-point lock) | Yes, often patented |
| Combination (keyless) | Padlocks, key safes | Not applicable (code) |
How can I tell what type of key I have?
Three clues are usually enough:
- The shape: flat and thin = pin tumbler key; thick with a wide bit = lever key; round and hollow = tubular key.
- The markings: a brand name (BKS, Vachette, ABUS, DOM, ISEO…) and a number indicate a patented key, copied with the key registration card.
- The number of points: a long key with several rows of dimples often belongs to a multipoint security door lock.
