Door opening detailsABC Slotenservice · Based in Boechout, Belgium
Locked out, dealing with a broken lock or planning to change your keys? ABC Slotenservice provides locksmith assistance for homes and businesses in Antwerp and surrounding areas. You can explain your problem in English. We check the situation, discuss the available solution and explain the cost basis before agreed work begins.
For urgent help, call directly. Tell us your address so we can confirm availability and an estimated arrival time. A message alone does not confirm a booking.

Emergency locksmith
If your door has closed behind you, the key is missing or the lock no longer responds, tell us what happened before trying to force it. A door that has simply clicked shut can require a different approach from one that is locked with the key, has a damaged mechanism or uses an automatic multipoint lock.
We assess the door and choose an appropriate opening method. Where the situation allows, we aim to preserve the existing lock and door. Damage-free opening cannot be promised for every lock, particularly when parts have already failed or a previous attempt has caused damage. If replacement or additional work is needed, we discuss it with you.
After a break-in, the immediate question is whether the entrance can be secured again. Tell us about damage to the frame, door, cylinder and fittings. Where police attendance or evidence collection is involved, coordinate that before repairs alter the damaged area. For immediate danger to people, contact the emergency services first.
Urgent and planned work
We look at how you use the entrance, what has changed and which parts still work. Detailed service pages linked below are in Dutch; you can contact us in English about any of these services.

Door opening detailsReplacement after wear, damage, a move or lost keys. We check the cylinder dimensions, the existing lock and the required inside operation before selecting a part.
Cylinder replacement detailsA key that turns without unlocking or a handle that no longer moves the locking points needs diagnosis. The fault may be in the cylinder, gearbox or another part of the system.
Multipoint lock repairsIf you need to pull, lift or push the door to turn the key, the problem may involve alignment. We check hinges, clearance, strike plates and the locking mechanism together.
Door adjustment detailsA suitable cylinder, protective fittings and a sound door must work together. We discuss improvements that suit the entrance and assess damaged parts after a break-in.
Door security adviceA lost mailbox key or a broken cam lock does not always mean replacing the whole mailbox. The opening, fastening and cam position must match the replacement.
Mailbox lock replacementFrom the first call to the final check
You do not need to know the Dutch name for every lock part. Explain what the key or handle does and when the problem started. Tell us if the door still opens, if somebody is inside and whether another entrance is available.
For a planned appointment, photos help us prepare. They do not always show the exact dimensions or internal damage, so the final assessment may need to happen at the door. Let us know who can give access and approve the proposed work.
Call for urgent assistance or send a message for planned work. Include the address, door type and the access you still have.
We discuss availability, an estimated arrival time and how the visit is charged. Ask about labour, travel, materials and VAT before confirming.
The technician checks the entrance and explains the proposed repair or replacement. Any additional work should be discussed before it is carried out.
We check the normal opening and closing operation, test supplied keys and explain any new hardware. Keep the invoice and product information for future service.
Clear cost information
The cost depends on the job: gaining access, identifying a fault, fitting a cylinder and repairing a damaged multipoint system require different work. Location, the timing of the visit and the parts needed also affect the quote.
Contact ABC Slotenservice with your address and a description of the problem. We explain the cost basis for the visit and which parts of the quote depend on inspecting the door. Any further repair or replacement is discussed with you before the work begins.
If you need several keys, a thumbturn or matching cylinders for more than one door, mention that when booking. This helps us prepare a proposal for the complete setup you need.
GERDA locks and key management
A replacement cylinder should suit the door thickness, protective fittings and locking mechanism. You may also need a particular inside operation, a compatible emergency function or a coordinated system for several doors. The most expensive cylinder is not automatically the right answer if other parts of the entrance are damaged or poorly adjusted.
ABC Slotenservice supplies and installs GERDA products within its range. For additional keys to a protected system, we first check the model, available card or order information and the authorised ordering route. Availability and lead time are confirmed for the specific request; we do not promise immediate duplication of every GERDA key.
If a key is lost, a spare copy does not disable the missing one. Consider which doors it opens and whether it can be linked to your address. We can discuss whether the affected cylinders or locking combination need to change. Read more about GERDA locks and key requests on our Dutch website.

Smart and electrical access
A smart lock, an electric strike and a motorised lock solve different problems. Some devices turn the existing cylinder, while other systems electrically release a latch or operate the locking mechanism. The desired access method is only one part of the choice: the door must also close and lock reliably.
We check the existing hardware, power supply where needed, inside operation and alternative access if a battery or connection fails. For apartments and shared entrances, the building manager should be involved in changes to common access. You can ask about smart lock installation or electrical locking systems; those detailed pages are in Dutch.

Frequently asked questions
Call if your situation is different or you are unsure which service you need.
Yes. You can contact ABC Slotenservice in English. Explain what happened, which access you still have and where the property is. You do not need technical Dutch vocabulary.
You can call 24/7 for urgent lock problems. Attendance and an estimated arrival time are confirmed for your address and the availability at that moment.
The timing depends on your location, traffic and technician availability. Call with the full address for an estimate. We do not promise the same arrival time for every customer or every area.
Not necessarily. The appropriate method depends on the door, the locking position and the fault. We aim to preserve working parts where possible, but cannot guarantee damage-free opening in every situation.
We may ask for identification and evidence that you are authorised to access the property. If your documents are inside or you are acting for someone else, explain that when booking so the appropriate check can be arranged.
Yes, subject to the appropriate authorisation and access arrangements. Tell us whether the issue concerns your own door or a shared entrance and who can approve the work. Agree any payment arrangements with the relevant party beforehand.
Yes. Contact us for cylinder replacement, door adjustment, security improvements, smart locks or other planned work. Send useful photos and your location so we can prepare and discuss an appointment.
Not always. The cylinder is the part operated by the key. If the lock case and the rest of the door are suitable and working correctly, replacing only the cylinder may be enough. We check the cause and compatibility first.
