Good to know: The most important differences when it comes to keys

Conventional keys and reversible keys, code numbers and owner protection cards, technical and legal copy protection. The differences aren’t always clear. Here we will explain them to you.

Code Number vs. Owner Protection Card

If the cylinder is equipped with a key that has a code number, the code is located on the key or on the card delivered along with it. In the case that you need a replacement key, your specialized retailer will create a new one using this code number. This ensures the consistent quality of all keys. Your key will always be created as an original and is not just a copy.

The code card also has the advantage that your key doesn’t leave your possession. You simply give the specialist your code card and then he will create a replacement key for you.

It is not possible to tell how many keys have been created using the code. There is no registration.

Owner protection cards guarantee the highest level of security. They are created for patented door cylinders. Only the person who possesses the owner protection card and can present it at a specialized retailer will receive a replacement key. That way you have peace of mind, knowing that an unauthorized person is not having your key copied and gaining access to your house or property.

Reversible Key vs. Conventional Key

Unlike conventional keys, reversible keys can lock using both sides. This means that the key will fit into the lock and lock it regardless of which direction it is facing when it is inserted. A reversible key provides a great deal more comfort, especially in bad lighting or for people with impaired vision. Additionally, the reversible key does not have any sharp-edged grooves. This makes carrying it in a pant pocket, for example, much more comfortable.

Technical vs. Legal Copy Protection

As regards copy protection for keys, there is a difference between technical and legal copy protection. Legal copy protection means that a patent or trademark protection guarantees that another manufacturer will not be allowed to manufacture your key in the same way. This means that identical key moulds can not enter circulation and thus cannot be used by a random person to create a copy of your key. Strong technical copy protection means that the technical composition of the key ensures that the key cannot be copied by standard commercial key copying machines. In making your decision to purchase a lock cylinder, be sure that the lock system you utilize has high technical as well as legal copy protection.
