Question 1

My key turns freely — door blocked, what should I do?

Accepted Answer

Do not force anything: you risk pushing the broken piece deeper. Our technicians have specific extraction tools that retrieve the broken piece without damaging the cylinder in 90% of cases. If the cylinder is damaged, we replace it immediately.

Question 2

My front door has sagged and rubs — is it repairable?

Accepted Answer

Yes. Sagging usually comes from hinges that have become misaligned over time. Adjustment or replacement of hinges, checking the frame and adjusting the threshold — a quick intervention that avoids changing the entire door.

Question 3

After an attempted break-in, do I need to change the entire lock?

Accepted Answer

Not always. Honest advice: if only the cylinder is damaged, it is sufficient to replace it (with an A2P BP2 or BP3 certified model for more security). The multipoint lock itself is often intact. We provide a photo report and quote for your insurance.

Question 4

Faulty communal door closer — do you intervene for property managers?

Accepted Answer

Yes, we regularly work with property management companies in Luxembourg. Periodic maintenance of Geze, Dorma, Assa Abloy door closers, intervention on mandate and detailed quote for general assembly.

Question 5

Why does my A2P multipoint lock stiffen at the end of its travel?

Accepted Answer

Two main causes: the frame has slightly sagged and the side bolts no longer enter the strikes straight, or the Kaba/Iseo cylinder has a fatigued return spring. We realign the strikes, lubricate the rods and replace the cylinder if necessary with an A2P BP2 or BP3 certified model. Your insurance will appreciate it.

Question 6

My Geze or Dorma door closer slams, how can I adjust it?

Accepted Answer

A hydraulic door closer that slams has lost its oil or its speed adjustment screws (V1 closing, V2 final snap) have moved. We adjust both screws, bleed if recoverable, otherwise replace the Geze TS 2000/4000 or Dorma TS 83 unit. Critical in co-ownerships to preserve the fire door and door frames.

Question 7

My access control badge no longer opens the building door, what should I check?

Accepted Answer

Firstly, the electronic head's battery (CR123 or CR2 battery depending on Salto, Iseo, Kaba model), then the badge programming which may have been revoked by the property manager. We diagnose the system, reprogramme the badges and replace the head or the central unit if faulty. Intervention under property manager's mandate.

Question 8

After a break-in, how long does it take to temporarily secure my front door?

Accepted Answer

Emergency intervention in 1 to 2h in Luxembourg City depending on the time. Immediate securing (panels, metal reinforcements, temporary cylinder), photo report for insurance, then return within 48 to 72h with the definitive multipoint lock and A2P BP2 cylinder. Send us a WhatsApp photo for a quote in 15 min.

Question 9

My communal fire door no longer closes by itself, is it a legal problem?

Accepted Answer

Yes: a fire door must imperatively close by itself to maintain its EI30/EI60 rating. We replace the compliant Geze or Dorma door closer, check the spring hinges and the intumescent seal. Priority intervention for property managers — compliance report provided.

Question 10

My front door brush seal is worn, can it be replaced without removing the door?

Accepted Answer

Yes, in 90% of cases. The bottom brush seal (threshold) and peripheral EPDM seals are changed in situ in 30 to 45 minutes. This restores air/water tightness and reduces thermal losses by up to 15% on a well-insulated entrance door. Universal parts suitable for most aluminium and PVC frames.
