Lock cylinder replacement

The lock cylinder is a key component of many locks, and its condition directly affects how the locking system works. Over time, it can wear out, make the key difficult to turn or begin to develop other operating problems.


We carry out lock cylinder replacements in South Tenerife when there is a fault, deterioration or simply a desire to update the existing system. Before replacing it, we check the characteristics of the door and lock to assess the most suitable option for each access point.

Lock replacement

If a lock is damaged, worn or has stopped working properly, we can assess whether it should be replaced. We also replace locks when a customer wants to upgrade an outdated locking system or improve the security of a home or business.


Not all doors or locks are the same. That is why, before carrying out a lock replacement, we assess the existing system and the characteristics of the access point to determine the most appropriate work.

Jammed or damaged locks

A lock that starts to jam can eventually become a bigger problem. If the key is difficult to insert, hard to turn, the mechanism jams or the door does not open and close normally, the system should be checked.


We analyse the source of the problem to assess the condition of the lock and determine what work is required. Depending on the situation, it may be necessary to work on the mechanism or consider replacing the lock or cylinder.

Lock replacement due to lost or stolen keys

Losing your keys is not only inconvenient because you cannot access the property. If you do not know where they are or they have been stolen, there may also be a security concern.


In these situations, we can help you regain access if necessary and then assess whether the lock cylinder or lock should be replaced. Once the relevant system is replaced, the old keys will no longer grant access.
