What an access control system does
An access control system lets you decide who gets in, through which door and when — without keys that get lost or copied. Instead of a key, each person opens with their own code, card, fingerprint, face or phone, and you can give or remove access at any time.
La Sagrada Cerrajería installs access control across Barcelona from our base in Sant Gervasi, for homes, residential buildings, offices, shops and holiday lets. We explain the options in English and leave everything set up and working before we go.
Ways to open your door
Code: a keypad on the door and a code for each person, which you can change or cancel whenever you like. Proximity card: each user opens by tapping their card, and a lost card is simply deactivated. Fingerprint and face recognition: biometric locks that only open for authorised people — no keys, codes or cards. Phone: open, lock and check the door from an app, wherever you are.
Smart models add time-limited access for guests, cleaners or staff, and an entry log with a notification every time someone comes in.
Homes, buildings, offices and holiday lets
Homes. Open with your phone, a code or your fingerprint, give access to family or your cleaner without handing out keys, and see who came in and when.
Residential buildings. We set up master-key systems so each neighbour opens their own door and the shared areas with a single key, while the building manager keeps a master key. If you'd rather use a code or card on a shared door, we'll tell you which electronic lock suits it.
Offices and shops. Each employee gets their own code or card, and when someone leaves you cancel their access instead of changing the lock. Need to secure the premises too? See our business security service.
Holiday lets. A code or app access for each booking that expires when the stay ends — no key handovers, no lockboxes, and no changing the cylinder between guests.
Smart home: connecting your door
The smart-home part we handle is the door. We install smart locks compatible with Alexa, Google Home and Apple HomeKit, from brands such as Nuki, Yale and Tedee, and pair them with the app and your voice assistant. You can open from your phone, check whether you left the door unlocked, or get an alert whenever someone comes in.
Some models, like Nuki, unlock automatically when your phone arrives and fit over your existing cylinder with no building work. For more on each type, see our smart locks page.
Door first, technology second
Access control doesn't replace a good lock — it complements it. Before installing anything we check your door and cylinder. If the cylinder is weak, we recommend an anti-bumping security cylinder, which is what actually stops a break-in, and build the access system on top of it.
Access control prices in Barcelona
A smart lock costs €400–700 in total, device and installation included, depending on the model and your door. For buildings, offices or premises with several doors, the price depends on the number of entrances and the system you choose. Either way you get a fixed price before we start, a proper invoice and a 6-month guarantee on the work.

Frequently asked questions
Electronic locks with a keypad (PIN code) or proximity card, biometric locks with fingerprint or face recognition, and smart locks you open from your phone. For buildings and businesses we also set up master-key systems. We check your door first and recommend the system that suits it.
A smart lock costs €400–700 in total, device and installation included, depending on the model and your door. For several doors or a building or business entrance, the price depends on the number of entrances and the system — we give you a fixed price before we start.
Yes. We install compatible models from brands such as Nuki, Yale and Tedee, and leave the lock paired with the app and your assistant so you can open, lock or check the door from your phone or by voice.
No. With a code, card or phone system you simply cancel that person's access and, if needed, create a new one. The lock stays the same and nobody else is affected.
These locks run on batteries, not mains power, so a power cut doesn't affect them, and they warn you when the battery is low. Without Wi-Fi you can still open with the keypad, card or your phone over Bluetooth — you only lose remote control. Most models also have a mechanical key or emergency power backup.
Usually not. Some models, like Nuki, fit on the inside over your existing cylinder. Others replace the lock with one that has a keypad or reader. We check first and tell you which option is least work for your door.
Yes. Every job comes with a 6-month guarantee and a proper invoice.
