Non-destructive entry when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. Changing just the cylinder is a 30-45 minute operation per door. The mechanical lock remains, and we only replace 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 the one we recommend when the lock is of good quality and in good condition. Changing the complete lock costs more and is justified when the lock is old or of low quality, and we want to take advantage of the change to upgrade the security level. This operation takes 60-90 minutes per door. When a customer calls us for an emergency (keys left inside, lost key, locked lock), we first assess if non-destructive entry is possible. Most standard locks can be opened with professional techniques (lock picking, impressioning, pin manipulation) in 15-30 minutes without damaging the cylinder. This saves the customer the cost of replacing the entire cylinder. For high-end anti-bumping cylinders, non-destructive entry may not be possible, and the only solution is to drill out the cylinder and replace it, which is more expensive but leaves the door like new with a new reinforced security cylinder.

Complete lock or just cylinder change depending on the case. Quality brand and a new set of keys. 30-day warranty on labour. Premium cylinders with official manufacturer's warranty up to 10 years. For a home on the Costa Blanca with medium risk (urbanisation with neighbours, not isolated), we recommend a medium-high quality anti-bumping cylinder. Brands like Tesa T80, Mottura Champions, or Cisa Astral are our best sellers. These cylinders have security pins that prevent the bumping technique — that sharp blow with a special key that opens any standard cylinder in less than 60 seconds. They come with a registered security key, which cannot be duplicated without authorisation at any hardware store. And they have European EN1303 certification, guaranteeing resistance to manipulation for years. Their cost is reasonable, and the real security improvement is enormous.

The price for changing cylinders in Sant Joan Despí usually ranges between 54 and 350 euros. The final figure depends on the condition of the property, materials, and working time.
