Replacing only the cylinder takes 30-45 minutes 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. This is the most economical option and what we recommend when the lock is of good quality and in good condition. Changing the full 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 client calls us for an emergency (keys left inside, lost key, locked out), 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 out the cylinder and replace it, which is more expensive but leaves the door like new with a reinforced security cylinder. Examples: water leak • power cut • air conditioning not cooling • stuck blind • painting…

30-day warranty on workmanship. Premium cylinders with official manufacturer warranty up to 10 years. Full lock or cylinder replacement depending on the situation. Quality brand and a new set of 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 under 60 seconds. They come with a registered security key, which cannot be copied without authorisation at any hardware store. They also have EN1303 European certification, guaranteeing tamper resistance for years. Their cost is reasonable, and the real security improvement is enormous.
