When a client calls us with an emergency (keys left inside, lost key, locked lock), we first assess if non-destructive entry is possible. Most standard locks can be opened using professional techniques (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 out and replace the cylinder. This is more expensive but leaves the door like new with a new, reinforced security cylinder. 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 will not work with the old one. This is 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 poor quality and we want to take advantage of the change to upgrade security. This operation takes 60-90 minutes per door. Non-destructive entry when possible, complete lock or cylinder replacement, installation of high-security anti-bumping cylinders.

If the lock is in good condition, only changing the cylinder is the most economical. If it's old or of poor quality, a full lock change is a better investment. 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 – 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. And they carry European EN1303 certification, guaranteeing manipulation resistance for years. Their cost is reasonable, and the real security improvement is enormous. 30 days on labour. Premium cylinders with up to 10 years official manufacturer warranty.
