Quick summary
Replace the cylinder if it is over ten years old, lacks the UNE EN 1303 grade 6 seal, has been tampered with, you have lost a key or you have just moved in. The cost is far below your insurance deductible after a burglary.
Why are old cylinders vulnerable?
Standard euro-profile cylinders made before 2010 do not include protection against bumping (opening with a special key and a quick tap), picking or pulling. In Barcelona, most flat burglaries happen through the front door and the entry is usually achieved in under 60 seconds when the cylinder is not security-rated.
What defines a true security cylinder
A high-security cylinder meets the UNE EN 1303 grade 6 standard and includes anti-bumping, anti-picking, anti-drilling, anti-pulling protection and a key copy controlled by an ownership card. Recognised brands: Tesa T80, MUL-T-LOCK MT5+, Abus Bravus, Kaba Expert Plus, Cisa AP4 S. Always ask for the data sheet with the certification.
Clear signs you should change it now
Key that no longer enters smoothly, marks around the keyhole, paint chipped near the lock, a neighbour who has just been robbed, recent move with unknown number of keys in circulation, lost key or old keys without an ownership card. Any of these warnings justifies an urgent visit.
How long the change takes and how we do it
Replacing the cylinder on a standard door takes 20 to 40 minutes. We measure the current cylinder (length is given by two numbers: outside + inside in millimetres), fit the new one matching or reinforcing the length, check the door closes without effort and hand over the original keys plus the ownership card for future copies.
When to call
Call if your door has been forced, you have lost keys, you have just bought or rented a flat, the cylinder is jammed, turns roughly or shows signs of manipulation. We come the same day with a certified anti-bumping cylinder ready to install.
Frequently asked questions
How much does a security cylinder cost in Barcelona?
It depends on the model and whether a magnetic shield is needed. We give a closed quote before starting after seeing the cylinder or a WhatsApp photo. In general, a certified anti-bumping cylinder costs far less than your insurance deductible after a burglary.
Can I use any cylinder or does it have to be specific?
It must be a euro-profile cylinder with the exact length of your door (outside + inside in mm). If the cylinder sticks out more than 3 mm outside, it is vulnerable to pulling even if it is a security model. We measure it and combine it with a magnetic shield if needed.
What is bumping and why does it matter?
It is opening a standard cylinder by inserting a special key and tapping it sharply. It takes under 30 seconds, breaks nothing and leaves no trace for the insurer. UNE EN 1303 grade 6 cylinders include anti-bumping pins that block the technique.
Do I need to change it if I just moved in?
Strongly recommended. You do not know how many copies of the old key are in circulation: previous tenants, family, cleaners, technicians. Replacing the cylinder on moving day is the fastest and cheapest way to make sure only you open your door.
Do you work with property communities and administrators?
Yes. We change cylinders on building entrances, meter rooms, storage units and private flats. We coordinate with the administrator, invoice the community and deliver keys with an ownership card for controlled future copies.
Do you come the same day if my door has been forced?
Yes. We prioritise emergencies in Barcelona city and metropolitan area. Send a photo of the cylinder and lock by WhatsApp to +34 645 91 65 45 and we will be there in hours with a security cylinder ready to fit.
