Non-destructive opening when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. Changing only 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 what 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 the opportunity to increase the security level. This operation takes 60-90 minutes per door. When a client calls us for an emergency (keys left inside, lost key, locked door), we first assess if non-destructive opening 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 client the cost of replacing the entire cylinder. For high-end anti-bumping cylinders, non-destructive opening 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 looking new with a new, reinforced security cylinder.

30 days on labour. Premium cylinders come with an official manufacturer's warranty of up to 10 years. Complete lock change or just the cylinder, depending on the case. Quality brand and new set of keys. For a property on the Costa Blanca with medium risk (urbanisation with neighbours, not isolated), we recommend a medium-to-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 copied without authorisation at any hardware store. And they have EN1303 European certification, guaranteeing tamper resistance for years. Their cost is reasonable, and the real security improvement is huge.

The price for cylinder changes in Parets del Vallès typically ranges between 54 and 350 euros. The final figure depends on the property's condition, materials, and working time.
