English-speaking locksmith for smart and electronic locks — keyless entry for your home and remote access for holiday flats. Supplied, installed and explained.
A smart lock lets you open your door with your phone, a code or a fob — and lets you give (and revoke) access without cutting a single key. La Sagrada Cerrajería supplies and installs the leading smart and electronic locks in Barcelona, and sets them up so they actually work on your door, not just in the brochure.
We explain the options in English, fit the hardware cleanly, and show you how to use it before we leave.
If you rent out a flat, a smart lock removes the biggest headache: key handovers. Send guests a time-limited code, see when they check in, and change access between stays without meeting anyone or hiding keys in a lockbox.
We advise on models that suit short-term rentals and integrate with the platforms and apps hosts actually use.
We work with recognised brands such as Nuki, Yale and Tedee, choosing the one that fits your existing door and cylinder. Many models install over your current lock, so you keep a physical key as backup while gaining keyless entry — the best of both worlds.
A good smart lock is convenient and secure: encrypted access, auto-lock, and alerts if the door is left open. We pair it with a solid high-security cylinder where needed, and explain battery life and backup so you're never locked out by a flat battery.
Explain the problem and agree the price in plain English — no translation stress mid-emergency.
Real round-the-clock cover: nights, weekends and holidays included.
A clear quote before we touch anything. No surprises on the bill.
Proper invoice at no extra cost — useful for home-insurance or landlord claims.
Local to the zona alta: we reach Sarrià-Sant Gervasi and central Barcelona quickly.
Non-destructive methods that protect your door and cylinder.
Yes, when chosen and installed well. Reputable brands use encrypted access and auto-lock, and we pair them with a high-security cylinder where it makes sense. We only fit models we trust.
With most models, yes. Many smart locks install over your existing cylinder so you keep a key as backup while gaining phone/code access.
That's exactly what a smart lock is for. You send a time-limited code or app access for each stay, so no key handovers or lockboxes, and you can revoke access anytime.
Good models warn you well in advance and keep a physical-key or external-power backup. We explain the backup for your specific model at installation.
