Fragment of broken key and lock

KEY POINTS

Do not persist with the remaining piece and do not push the fragment back into the cylinder. In some cases, extraction alone may suffice: replacing the entire lock is not always necessary.

Start by inspecting, without forcing anything

Is the door open, simply shut without locking, or locked? Does the fragment extend beyond the key entry point? These observations guide diagnosis. If the door is open, keep it open to avoid turning a cylinder failure into an inability to enter.

Keep the key fragments and, if you have one, prepare a spare. A worn or already cracked key may break, but resistance from the lock, misalignment of the door, or a faulty cylinder may also be the cause.

Actions that may complicate the repair process

Avoid glue, random tool insertion, and prying with pliers. These can drive the fragment in, damage the keyway, or jam internal parts. Do not heat the cylinder and do not pour in any improvised product.

A protruding piece is not necessarily free: it may still be held by the mechanism's position. If removal requires effort, it's best to stop. A professional can assess the possibility of extracting the fragment before recommending a replacement.

Prepare for your call to the locksmith

Indicate your commune, the type of door, its position, and the brand visible on the lock. A photo of the keyway and the door edge, when accessible, helps identify the material. Also specify if you have another entry point.

Request the cost of the visit, any additional charges, and the billing principle. The quotation must specify the planned intervention prior to work. At a late hour, availability and timing must be confirmed during the call: they depend on the situation and ongoing interventions.

After extraction: understand the cause

If the cylinder operates normally with a sound key, it may be retained. If it still sticks, inspect the cylinder and the door lock rather than creating additional copies from a worn key.

Before replacing it, check the dimensions and compatibility with the lock and door furniture. For a certified assembly, the replacement must match the approved configuration. For assistance in Annecy and nearby, contact MULTISECU describing the situation.
