Door Opening in Brussels: How We Work
Slammed door, lost keys, jammed lock — each situation calls for a different approach. After years of opening doors across Brussels and Brabant, one thing is clear: whenever the lock condition allows, the door opens without a scratch, without replacing a single part, and without any surprise on the invoice.
Three Techniques, Depending on Your Situation
Every door tells a different story. A simple latch bolt that slammed shut is not the same as a Fichet cylinder locked with a double turn. Here's how we assess the situation and choose the right method.
Locked-out door: bypass opening
When your door has slammed shut and the lock has not been turned with a key, we use a bypass technique. Using thin tools slid between the frame and the door panel, we push back the latch bolt without touching the cylinder. This intervention takes on average 5 to 10 minutes and leaves no trace on your door. It is by far the most common scenario and the simplest to resolve.
Read our complete guide: locked out in Brussels, what to do? for the right steps to take while you wait for our arrival.
Locked door: lock picking and decoding
If the door has been locked with a key or the mechanism is seized, we use lock picking or decoding to open the cylinder. These techniques require precise skill and tools adapted to each brand. We work regularly on locks from Fichet, Bricard, Vachette, Mul-T-Lock, Picard, and Wilka. The intervention time ranges from 10 to 30 minutes depending on the complexity of the cylinder. Your lock remains intact and fully functional after the opening.
Cases requiring drilling
In roughly 5% of cases, when the mechanism is too damaged or the cylinder is a high-security anti-pick model, drilling becomes the only option. Our technicians perform a targeted drill that affects only the cylinder, using non-destructive methods when the mechanism allows, to avoid damaging the door or the lock body itself. The drilled cylinder is then replaced with an equivalent or higher-grade model. Learn more about our lock replacement service for details on the brands and cylinders we install.
Types of Doors We Cover
We handle every type of door found in Brussels and Brabant:
- Apartment doors — entrance doors in wood or metal, fitted with European-profile cylinders or multipoint locks. This is the most common type of intervention across the Brussels municipalities.
- House doors — front doors in solid wood, PVC, or aluminium, with mortice or surface-mounted locks from brands such as Vachette, Bricard, or Fichet.
- Armoured doors — reinforced doors equipped with high-security multipoint locks. We carry the tools needed to open armoured doors from Fichet, Picard, and Mul-T-Lock using non-destructive methods when the mechanism allows, to avoid damaging the reinforcement.
- Garage doors and commercial premises — tilt-up, sectional, or swing doors with round-profile or lever locks. We also work on metal roller shutters for shops and offices.
Smart Locks: When Technology Locks You Out
We're seeing more Nuki locks in Brussels every month, especially in new builds and Airbnb flats. The problem? They fail like any electronic device. Dead battery, Bluetooth that won't connect, an app that crashes after an update — the result is the same: you're standing outside. Most smart locks have a mechanical backup. And when they don't, we reconfigure the electronic module on site.
What Sets Us Apart
There are plenty of locksmiths in Brussels. But not all of them work the same way. Here's what our clients notice after an intervention:
- The quoted price is the price you pay — no hidden call-out fees, no "complex lock surcharge" invented on the spot.
- We don't replace what doesn't need replacing — if the lock works after opening, we won't push you to change it.
- Every technician carries a full stock — Fichet, Bricard, Vachette, Mul-T-Lock, Picard, Wilka cylinders. No need for a second visit.
- We know Brussels buildings — access codes, concierges, building managers, Art Nouveau entrance doors… after years of experience, we know how to get to your door.
