Baix Llobregat · Barcelona
Upgrading a lock usually follows a scare: an attempt on the stairwell, a neighbour who was broken into, or a door that simply feels flimsy. Before selling anything we look at the door you actually have — quite often the cylinder and a security escutcheon are enough.
La tarifa es la misma en los 54 municipios de cobertura: la distancia no se cobra aparte. Lo que mueve el importe es la hora, el día y el tipo de cerradura.
1
We look at what you have
Very often the cylinder and a security escutcheon are enough, and a whole new lock would be money spent on the wrong part of the door.
2
Understand what you are buying
Anti-bump, anti-drill, anti-snap — they resist different attacks. You get told which one matters for your door rather than a list of features.
3
Fitted by appointment
Installation work: it comes by van, measured first, agreed in advance.

Keys accounted for
You get the full set, counted, and the old lock. If several doors are keyed alike, you get one key that opens them all.
Castelldefels has 5,415 people per km², against 1,535 across the towns we cover. In a city like this the arrival time is not decided by the road, it is decided by the last hundred metres: getting there is easy, parking is not. That is why emergencies go by motorbike, and it is not a brochure line — it is the difference between leaving it at your door and circling the block in a van while somebody waits on the landing.
Castelldefels registers 2,908 hotel beds for 69,689 registered residents, where the median across our towns is 304. The place fills with people who do not live here, and a good share of the summer callouts are exactly that: holiday flats where the key belongs to an owner nobody can reach, doors that shut themselves with the luggage inside, hire cars with the keys still in them. In those cases the lock is not the first question — the first question is who is entitled to have it opened, because without that nobody touches the door.
27.1 % of the main homes in Castelldefels are rented, against a 18.5 % median. Where there is a lot of renting the most repeated job is not an emergency at all: it is the cylinder change between one tenant and the next, booked in advance and done in half an hour. It always brings the same question, so here it is. The owner can ask for it once the property is free. The tenant can change it during the contract, but has to leave the lock as it was — or hand over a copy — when they go. And for an opening, a rental contract in your name is perfectly good proof of address.

35-50 min desde la base en Cubelles, calculado sobre las rutas reales por carretera y con margen para salir y para el tráfico. En hora punta o en agosto puede alargarse, y si va a alargarse te lo decimos por WhatsApp antes de que te comprometas, no al llegar.
Desde 99 €, IVA incluido. El importe final depende de la hora, del día y del tipo de cerradura, y lo recibes entero por WhatsApp antes de que salga nadie. La distancia hasta Castelldefels no se suma al precio: la tarifa es la misma en todos los municipios que cubrimos.
Con cita. Es un trabajo de instalación: hace falta la furgoneta, el material y medir la puerta antes. Se acuerda día y hora, y en Castelldefels puede ser fuera del horario de oficina si te viene mejor.
Sólo con el propietario o la agencia detrás: quien autoriza que se abra esa puerta es quien responde de la vivienda, no quien pasa la semana en ella, y ningún cerrajero que trabaje legalmente puede saltárselo. Mándanos el contacto por WhatsApp y hablamos nosotros con ellos; suele ser un mensaje. Si la lleva una agencia, contestan antes de lo que la gente espera, porque la cerradura es suya.
Puedes cambiarla mientras dure el contrato, pero tienes que dejar la cerradura como estaba —o entregar copia— al marcharte. El propietario puede cambiarla cuando la vivienda queda libre. Si has perdido las llaves y no localizas al propietario, cambiar el bombín y guardar el viejo para devolverlo es la salida habitual, y además es la opción barata.
Cuenta qué ha pasado y dónde estás. Recibes el precio y la hora antes de que salga nadie.
