Replacing only the cylinder takes 30-45 minutes per door. The mechanical lock stays, and we replace only the inner cylinder where the key fits. The new key is completely different and won't open with the old one. It's the most economical option, and we recommend it when the lock is of good quality and in good condition. Replacing the entire lock costs more and is justified when the lock is old or of low quality, and we want to use the change to upgrade the security level. The job takes 60-90 minutes per door. When a customer calls us for an emergency (keys left inside, lost key, jammed lock), we first assess if non-destructive opening is possible. Most standard locks can be opened using professional techniques (lock picking, impressioning, manipulation) in 15-30 minutes without damaging the cylinder. This saves the customer the cost of a full lock replacement. For high-end anti-bumping cylinders, non-destructive opening may not be possible, and the only solution is to drill the cylinder and replace it, which is more expensive but leaves the door like new with a reinforced new security cylinder. Every Monday, we deal with repair requests for flats that have been closed for three months. The problems here are not the same as in other cities.

Manufacturer's official warranty 5-10 years depending on brand and model. Plus 30 days on labour. For detached houses, single-family homes in high-risk areas, or owners with previous experience of attempted break-ins, we recommend high-security cylinders like Cisa Astral S, Mul-T-Lock MT5+, Tesa T80 Plus, or Mottura Champions. These upgrade the rating to EN1303 grade 6 and include all anti-features (bumping, picking, drilling, extraction). They come with the manufacturer's burglary insurance warranty. This warranty is relevant. If, despite everything, a break-in occurs, and you can prove the cylinder was tampered with, the manufacturer covers part of the damage. Investing in a security cylinder like this loses its purpose if key copies can be freely made at any local hardware store. The registered key of a security cylinder can only be duplicated at the manufacturer's official distributor by presenting the owner's card we provide upon installation. Without that card, no copy is possible. This means you control exactly how many keys exist and who has them. You'll never have the uncomfortable doubt of whether a local locksmith or copier has saved your key's pattern for future use.

The price for copies and duplicates in Sant Boi de Llobregat typically ranges between €50 and €385. The final amount depends on the property's condition, materials used, and labour time. We always provide a fixed quote before starting. For apartments in blocks with neighbours, an active community, and natural surveillance, we recommend mid-to-high security cylinders like Tesa T80 or Cisa Astral. Effective anti-bumping, registered key (cannot be copied without your authorisation), EN1303 grade 5 certification (resistance to manipulation for years). Reasonable cost and a significant real improvement over standard options. For a property on the Costa Blanca with medium risk (residential area with neighbours, not isolated), we recommend a mid-to-high quality anti-bumping cylinder. Brands like Tesa T80, Mottura Champions, or Cisa Astral are what we sell most. These cylinders have security pins that prevent the bumping technique – that sharp knock with a special key that opens any standard cylinder in under 60 seconds. They come with a registered security key, which cannot be copied without authorisation at any hardware store. They also have European EN1303 certification, guaranteeing resistance to manipulation for years. Their cost is reasonable, and the actual security improvement is enormous.
