Help with a jammed lock — Annecy and the surrounding area

A lock can become jammed for various reasons. Here are the most common causes of a lock being stuck:

• Dust or dirt: debris can collect inside the cylinder and obstruct the mechanism, particularly if the lock is rarely used.
• Rust: moisture and oxidation can cause the lock’s metal components to seize.
• Wear: after years of use, worn components may prevent the mechanism from working properly.
• An attempted break-in: picking or drilling attempts can damage the mechanism.
• Incorrect use: forcing the key, turning it the wrong way or using a damaged key can harm the lock.
• A manufacturing or fitting fault: less commonly, the problem comes from the design, assembly or installation.

Ways to deal with a jammed lock

Start by identifying the cause of the problem. This helps determine the right approach. Depending on the diagnosis, the options may include:

Cleaning and lubrication

If the jam is caused by dust, rust or wear, a simple cleaning and lubrication may be sufficient:

• Apply a lock-specific lubricant that is approved for the particular lock
• If permitted by the manufacturer, use a key with a small amount of suitable lubricant and move it gently in and out
• Use a clean cloth to remove surface dust

This simple, non-destructive approach can help when dirt or friction is the cause.

Lock picking

Among the various techniques for unlocking a lock, picking is sometimes used by professional locksmiths of MULTISECU. This method offers numerous advantages:

Lock picking uses specialist tools to manipulate the cylinder’s pins without the original key. A trained locksmith may consider this method when the lock’s condition and design allow it.

This technique requires great dexterity and experience. Our locksmiths are experts in the art of lock picking. They know how to identify the right pick and insert it optimally into your lock, depending on the model and brand.

Where suitable, lock picking can provide non-destructive access. It aims to preserve the mechanism so the lock can continue to be used after the cause of the problem has been checked.

Lock picking is a complex technique to carry out. It can only be used on certain types of locks. Often, more destructive solutions such as drilling must be considered.

With the expertise of MULTISECU locksmiths, you may have the chance to see your lock unbolted by picking, without any damage!

Drilling

If other methods are unsuitable, the locksmith may need to drill and replace the cylinder. This is a destructive method used when required, with care taken to protect the rest of the lock and door.

Contacting a professional locksmith

If the lock remains stuck, contact a professional locksmith. They can assess the fault, explain the options and use suitable equipment to restore access while limiting damage.
