Lock cylinder replacement (also called changing the barrel or replacing the lock core) is often the fastest and most cost-effective way to secure your door after losing keys, experiencing a break-in, or dealing with a worn-out lock. Our locksmiths in Brussels install certified cylinders, anti-pick and anti-drill, as part of our full locksmith services.
What types of lock cylinders do we install?
- High-security cylinders with protected profile (anti-drill, anti-bumping).
- Master key / single key solutions for multiple doors.
- Cylinders compatible with multipoint locks and modern security systems.
When should you replace a cylinder
- Lost keys or risk of unauthorized copies.
- Worn, jammed, or stuck cylinder.
- Upgrading to a high-security cylinder with a property card.
- In case of a broken key inside the lock.
Why choose a high-security cylinder?
Choosing a security cylinder is the best way to protect your home against burglary. Unlike a standard lock barrel, a certified cylinder offers specific protections:
- Anti-pick and anti-bump protection to prevent forced opening.
- Anti-drill and anti-pull reinforcements for maximum resistance.
- Property card to prevent unauthorized key duplication.
- Greater durability and compliance with home insurance requirements.

« Had an old lock to replace urgently. Cosmin managed to find a match after enquiring with 7 factories. He was very transparent on price and process from start to finish. And price was very fair. I would definitely recommend if you are looking for trustworthy genuine quality service. Hard to come across in that line of duty. Thanks Cosmin ! »

FAQ – Cylinder replacement Brussels
How much does cylinder replacement cost in Brussels?
The price depends on the type of cylinder (standard vs high-security), the brand, compatibility with a multipoint lock, and whether it’s an emergency (day/night). Labor starts from €25; travel fees may apply depending on area and schedule.
What is the difference between changing a cylinder and changing a lock?
Changing the cylinder (barrel/core) keeps the existing lock and hardware; only the part where you insert the key is replaced. Changing the lock means replacing the entire mechanism (case, rods, strike plate), which is usually more expensive and time-consuming.
Can I keep my old keys after replacing the cylinder?
Yes, but only if an identical cylinder (same profile/brand) is installed. In most cases, a new cylinder comes with a new set of keys (and sometimes a property card).
How long does a cylinder replacement take?
On average 20 to 40 minutes, depending on the model, access, and the condition of the door/lock. In emergencies, our locksmiths arrive quickly to minimize waiting time.
