Buying an apartment is an important event, but along with the excitement of moving into a new home comes the question of security. Many new owners wonder whether they should change the locks immediately after the purchase or keep the existing ones. Security specialists recommend not postponing this decision. Even if the previous owners seem completely trustworthy, it is impossible to know exactly who else may have keys to your apartment.
Why you should change the locks immediately after buying an apartment
Once the purchase is complete, the apartment belongs to you, but this does not necessarily mean that only you have access to it. Over the years, copies of the keys may have been given to different people.
For example, spare keys may still be held by:
- the previous owners;
- relatives or friends of the former residents;
- neighbours who were once given a spare set;
- former tenants, if the apartment was rented out;
- builders or technicians who carried out repairs.
Even if everyone says that no additional keys exist, there is no way to verify this. Replacing the lock or cylinder removes this risk and gives you full control over access to your home.
Do you always need to replace the entire lock?
Not necessarily. It depends on the type and condition of the existing lock.
If the door has a modern cylinder lock, replacing only the cylinder is often enough. This option is faster, less expensive, and provides you with a completely new set of keys.
However, if the mechanism is badly worn, the lock jams, shows signs of damage, or no longer meets modern security requirements, it is better to replace the entire lock.
A locksmith can recommend the best solution after inspecting the door and the existing mechanism.
When the entire lock should be replaced
Complete lock replacement is recommended in the following situations:
- the lock works irregularly;
- the key is difficult to turn;
- the lock has been repaired several times;
- there are signs of an attempted break-in;
- an outdated model with a low level of protection is installed;
- you want to improve the security of the apartment.
In these situations, installing a new lock is usually a more reliable solution than repairing the old mechanism.
How long does lock replacement take?
In many cases, the work takes between 20 and 60 minutes. The exact time depends on the type of door, the lock design, and whether additional adjustments are required.
If only the cylinder needs to be replaced, the work is usually completed even faster.
When the work is carried out by professionals, most lock replacements can be completed without damaging the door or affecting its appearance.
Which lock is best for an apartment?
When choosing a new lock, it is important to consider not only the price but also the level of protection it provides.
Specialists recommend paying attention to:
- the reliability of the manufacturer;
- protection against drilling and unauthorised opening;
- the type of cylinder;
- whether additional keys can only be made with an owner card;
- compatibility with your door.
If you are unsure which option to choose, a locksmith can help you select a lock that is suitable for your door and provides the required level of security.
Should you change the locks in a newly built apartment?
Even if the apartment is in a newly constructed building and you are its first owner, replacing the lock is still recommended.
During construction, the property may have been accessed by representatives of the developer, contractors, door installers, decorators, and other specialists. It is impossible to rule out the existence of additional sets of keys.
Replacing the lock after receiving the apartment ensures that only you have access to your new home.
Who should you contact for lock replacement?
If you have recently bought an apartment and want to improve its security, it is better to entrust the work to professionals. A locksmith will assess the condition of the existing mechanism and explain whether replacing the cylinder is sufficient or whether a completely new lock should be installed.
