Changing only the cylinder is a 30-45 minute operation per door. The mechanical lock remains, and we only replace the interior 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 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. The operation takes 60-90 minutes per door. Non-destructive opening when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. When a client calls us for an emergency (keys left inside, lost key, jammed 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 client 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 the cylinder and replace it, which is more expensive but leaves the door like new with a new reinforced security cylinder.

For a home 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 dry strike 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 European EN1303 certification, which guarantees resistance to tampering for years. Their cost is reasonable, and the real security improvement is enormous. 30 days on labour. Premium cylinders with official manufacturer's warranty up to 10 years. Full lock or just cylinder change depending on the case. Quality brand and new set of keys.

The price for changing lock cylinders in Cerdanyola del Vallès usually ranges between €54 and €350. The final figure depends on the property's condition, materials, and labour time.
