Changing tenants: a safe inventory of keys, remotes, and access points in Sant Cugat del Vallès

When a tenant changes, replacing every lock cylinder as a matter of course is not always the most useful step. First separate the custody of keys from the security of each access point. The aim is to know what is handed over, what is missing, and which item belongs to the home, garage, storage room, or shared building before deciding whether technical work is needed.

Make a simple inventory: main entrance, secondary doors, post box where relevant, storage room, parking space, and remotes or access cards. Record how many of each are handed over and whether each one opens and locks without force; do not put codes, key photographs, or serial numbers in a document that will be shared. In a garage, limit the check to using the authorised remote from a safe position. Do not try to copy, reprogramme, or erase remotes, and do not interfere with shared control panels or readers. For a storage room, establish whether it is a private door or a shared access point: the authorisations are different.

The inventory supports a proportionate decision. If the owner receives all expected keys and remotes, the cylinder works properly, and there is no indication of uncontrolled copies, a lock change is not automatic. If keys are missing, it is unknown who retains copies, the cylinder is worn, or the remote remains linked to the entrance, request a professional assessment of that specific point. Do not assume that the same solution is appropriate for the home door, garage, and storage room.

Before arranging work, establish who may authorise it. The owner, or a person with demonstrable authority, will normally decide about a private door; shared elements and the administration of community remotes should be handled through the person representing or managing the building. A tenant can report the issue, but should not order changes to a shared item or another party’s lock without authorisation. Keep the tenancy agreement, address, and authorisation where applicable available; the professional should be able to verify legitimacy without receiving sensitive information by message.

When requesting assistance in Sant Cugat del Vallès, state the district or local area and a safe arrival reference, without publishing codes or access instructions. The official Idescat municipal record identifies Sant Cugat del Vallès in the Vallès Occidental comarca; a precise location helps describe the case without disclosing security information. Tell the professional which entrance is involved, how many keys or remotes are missing, whether the door opens but does not close properly, and who authorises the work. If there is a fire, smell of gas, a person in immediate danger, or a risk of entrapment, contact 112 first.

Before changing a cylinder in rented housing, read the Teià tenant-and-owner agreement guide. Local information is available on the Sant Cugat del Vallès locksmith service page. You can also call or use WhatsApp, stating the access type, available inventory, and the person authorising the work.
