Blocked door: understanding the problem before acting
A door that will not open is not always the same thing as a door that has slammed shut. The distinction is crucial because it determines how we approach the job. A slammed door means the spring latch has engaged with your keys left inside — the lock itself has not been turned. A blocked door, on the other hand, involves a mechanical failure: the lock or the door structure itself is preventing the door from moving, even though you have the correct key in your hand.
We regularly arrive to find that someone has already tried yanking the handle, shouldering the door, or jiggling the key aggressively. In almost every case, these attempts have made the original problem worse and the repair more involved.
Common causes of a blocked door
After many call-outs across Brussels, the causes we encounter most often are:
- Timber swelling from moisture — extremely common in older Brussels houses, particularly between October and March. The wooden frame absorbs humidity and expands, effectively wedging the door in place. On damp days, we handle several of these before lunch.
- Frame misalignment — building settlement or even a heavy impact nearby can shift the door frame by just a couple of millimetres. The bolt no longer meets its strike plate. This is especially prevalent in the pre-war apartment buildings of Ixelles, Saint-Gilles, and Schaerbeek.
- Internal lock failure — a broken spring, seized pins, or a corroded cylinder. Robust locks from Fichet or Bricard are built to last, but after 15 to 20 years without maintenance, internal components do wear out.
- Key fragment lodged in the cylinder — a piece of a previously broken key remains inside, blocking any rotation. If that sounds like your situation, see our dedicated page on stuck keys.
How we deal with a blocked door
The technician starts with a visual and tactile assessment. He tests the handle, examines the gap between door and frame, and checks the cylinder. This takes two or three minutes but ensures we choose the right approach from the outset.
If the wood has swollen, a targeted mechanical release is often sufficient. For an internal mechanism fault, we proceed with cylinder picking or, in the most stubborn cases, controlled drilling. With a standard Vachette or Wilka cylinder, picking takes between 5 and 15 minutes. High-security cylinders from Mul-T-Lock or Picard may require precision drilling followed by a cylinder replacement.
Once the door is open, we check the full mechanism. If a replacement is needed, we carry the most common cylinders in our vehicle. You leave with a working lock and a fresh set of keys the same day.
Preventing recurring blockages
A few straightforward habits go a long way. Lubricate your cylinder twice a year with a dry PTFE spray — never WD-40, which clogs the pins over time. If your door drags or sticks during the summer or winter months, have the frame adjusted rather than forcing it. And if your key is becoming harder to turn each week, that is the cylinder telling you it is reaching the end of its life.
