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.
The rate is the same in all 54 towns we cover: distance is never charged separately. What moves the amount is the hour, the day and the type of lock.
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 from our base in Cubelles, worked out over the real road routes with room to set off and for traffic. At rush hour or in August it can run longer — and if it is going to, we tell you on WhatsApp before you commit rather than when we arrive.
From 99 €, VAT included. The final amount depends on the hour, the day and the type of lock, and you get it in full on WhatsApp before anyone sets off. The distance to Castelldefels is not added to the price — the rate is the same across all the towns we cover.
By appointment. It is an installation job: it needs the van, the parts, and the door measured first. We agree a day and a time, and in Castelldefels that can be outside office hours if it suits you better.
Only with the owner or the agency behind it — a booking confirmation is not the same as being entitled to have a lock opened, and no locksmith working legally can treat it as such. Send us the booking and the contact and we deal with them directly; it is usually one message. If the flat is managed by an agency they nearly always answer faster than you would expect, because it is their lock.
You can change it during the contract, but you have to leave the lock as it was — or hand over a copy — when you move out. The owner can have it changed once the property is free. If you have lost your keys and the landlord is not reachable, changing the cylinder and keeping the old one to hand back is the usual way through, and it is the cheaper option too.
