Cylinder Change: Why Is It Important and When Should You Do It?

Changement de Cylindre : Pourquoi Est-ce Important et Quand Faut-il le Faire ?

Cylinder change is a crucial security measure to consider in many situations, such as moving into a new home, losing your keys or having them stolen. This process involves modifying the internal mechanism of the lock so that the old keys no longer work, and issuing new keys. Here's everything you need to know about cylinder changing.


Why Change the Cylinder?


Moving to a New Home

When you move into a new home, it is impossible to know how many copies of keys are in circulation. Former owners, tenants or even contractors may have had access to your home. Changing the cylinders ensures that only you and trusted people have the keys to your new home.


Lost or Stolen Keys

If your keys are lost or stolen, there is a risk that someone could find them and gain unauthorized access to your property. The cylinder change eliminates this risk by making the old keys unusable.


Change of Tenant or Roommate

When roommates or tenants leave the accommodation, it is advisable to change the cylinders. This ensures that previous occupants no longer have access to the property, thereby increasing the security of new tenants or remaining occupants.


Improved Security

A cylinder change can also be part of an overall home security upgrade. If you want to improve security without replacing all the locks, this cost-effective method ensures that only new authorized keys can open the doors.


The Cylinder Changing Process


Removing the Lock Cylinder

The locksmith begins by removing the cylinder from the door lock. This cylinder contains the key mechanism of the lock.


Changing the Pins

Inside the cylinder are pins that match the cuts on your key. The locksmith replaces these pins with new ones that correspond to a different key.


Issuance of New Keys

Once the pins have been changed, the locksmith will give you a new set of keys. These new keys will work with the reconfigured cylinder, while the old keys will no longer be valid.


Reassembly and Testing

After the cylinder change, the lock is reassembled and tested to ensure it works properly with the new keys.


Benefits of Cylinder Replacement

  • Cost-effectiveness: Changing the cylinder is generally less expensive than replacing the entire lock.
  • Enhanced Security: It ensures that only authorized people have access to your property.
  • Practical: This process can be carried out quickly and efficiently by a professional locksmith.

When Should You Replace the Lock Instead of Changing the Cylinder?

Although changing the cylinder is often an excellent solution, there are situations where a complete lock replacement may be more suitable:

  • Worn or damaged locks: If the lock is old or damaged, replacing it may be more effective than changing the cylinder.
  • Security Upgrades: For major upgrades, such as installing smart locks or high security locks, a complete replacement is necessary.
