Locksmith in Leuven: room, home or shared entrance

For a call-out in Leuven, provide the complete address and postcode, including the district. A page covering Leuven does not mean that Janssens has a branch in every district; our registered address is in Schaerbeek and our service covers Belgium.

Locked out of a student room or residence?

Contact the residence manager or landlord to check whether an authorised spare key is available. Explain whether the affected lock belongs to your room or a shared entrance. Do not arrange changes to communal access without checking with the person responsible for the building.

A replacement key or a replacement cylinder?

Tell us whether your key is lost, broken or still available, and whether it opens other doors. An ownership card or a managed key system may affect how a replacement is ordered. See door opening for a locked entrance and cylinder replacement for a damaged cylinder.

KU Leuven residence: check the internal procedure

For the residences concerned, KU Leuven directs residents with forgotten or lost keys to Residence Management or the on-call resident. Check that option and your residence instructions first. For a privately rented room, ask the landlord who may authorise opening or replacement; the university procedure does not automatically apply.

You are back inside, but the key is still missing

Regaining entry does not make a lost key unusable. Say whether it opens only your room or also shared areas. The manager needs to assess the affected entrances before a replacement is chosen. Ordering an ordinary duplicate does not disable the old key.
