Non-destructive opening where possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders. Replacing 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 will not work with the old one. This is 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 advantage of the change to upgrade security. The operation takes 60-90 minutes per door. When a client calls us for an emergency (keys left inside, lost key, locked lock), we first assess if non-destructive opening is possible. Most standard locks can be opened with professional techniques (lock-picking, impressioning key, 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 as new with a new, reinforced security cylinder.

30 days on labour. Premium cylinders with official manufacturer warranty up to 10 years. Full lock or cylinder replacement as appropriate. Quality brand and set of new keys. For a home on the Costa Blanca with medium risk (urbanisation with neighbours, not isolated), we recommend a mid-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 – a sharp tap 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, which guarantees resistance to manipulation for years. Their cost is reasonable, and the real security improvement is enormous.

The price for cylinder replacement in Sant Antoni usually ranges between €54 and €350. The final figure depends on the condition of the property, materials, and time spent.
