Baix Llobregat · Barcelona
A lock that has gone stiff, a key that turns without opening, a door that no longer lines up: these rarely need replacing. It is usually wear, dirt, or a door that has dropped on its hinges, and repairing costs about half what replacing does.
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
Find out what it actually is
Stiffness is usually wear, dirt or a door that has dropped on its hinges — not a lock that has failed.
2
Clean, lubricate, adjust
In most cases that is the whole job. Repairing costs about half what replacing does, and it is the right answer more often than people expect.
3
Replace only what has to be
If a part is genuinely worn out, you see it before and after.
4
Tested with the door shut
A lock that works with the door open and binds when it is closed has not been fixed.
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 69 €, 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.
A call-out with diagnosis and no work done is 49 €, and you are told that before anyone leaves, so there is no surprise at the end. If the problem can be solved over WhatsApp, we solve it over WhatsApp and it costs nothing.
Yes, 24 hours a year round. The night and holiday rates are higher than a Tuesday morning, and you are told which one applies when you message. There is no hidden surcharge.
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.
