Frequently Asked Questions

Replacement is recommended after key loss, moving into a new apartment, after a breakup, after a burglary, or if the lock is functioning poorly and sticking.

In most doors, only the cylinder (the part where the key is inserted) is replaced. The entire lock mechanism inside the door is only changed in case of damage or specific requirements.

The price depends on the type of cylinder (standard, security, with anti-drill protection, etc.) and the complexity of installation. We’ll give you the exact price in advance based on the specific situation.

Yes, that’s possible. However, we recommend first checking the correct size and type to ensure the cylinder fits and meets security requirements.

The cylinder is measured from the center of the fixing screw to both sides – separately to the outside and separately to the inside. The result is two dimensions, for example 30/35 or 35/45 mm. Measuring can be done after disassembling the cylinder, which is the most accurate method. If you’re unsure, we’ll be happy to advise you over the phone or measure the cylinder on-site.

Yes. Based on the door type, location, and desired security level, we’ll recommend a suitable solution – from basic cylinders to certified security versions.

Yes, in most cases, replacement is necessary. Even if the lock isn’t visibly damaged, its mechanism and security may have been compromised.
