Damage-free opening where 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 internal 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 advantage of the change to upgrade the security level. The operation takes 60-90 minutes per door. When a customer calls us for an emergency (keys left inside, lost key, jammed lock), we first assess if damage-free opening is possible. Most standard locks can be opened with professional techniques (lock-picking, impression key, pin manipulation) in 15-30 minutes without damaging the cylinder. This saves the customer the cost of replacing the entire cylinder. For high-end anti-bumping cylinders, damage-free opening may not be possible and the only solution is to drill the cylinder and replace it, which is more expensive but leaves the door as new with a new reinforced security cylinder.

Complete lock change or just the cylinder depending on the case. Quality brand and new set of keys. 30 days on labour. Premium cylinders with official manufacturer warranty up to 10 years. 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 under 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 manipulation for years. Their cost is reasonable, and the real security improvement is enormous.

The price for changing lock cylinders in La Trinitat Vella typically ranges between 54 and 350 euros. The final amount depends on the property's condition, materials, and working time.
