Explaining the Types of Keys and Why They’re Advantageous for Selling.
Auto-lock condominiums are increasingly in demand as a reliable security measure.
In this article, we’ll introduce the main types and features of auto-lock systems, and explain why they can be an advantage when selling your property.
What Is an Auto-Lock Condominium?
An auto-lock condominium is a building equipped with an automatic locking system at the entrance. Once the door closes, it locks automatically. The entrance remains locked at all times, and only residents or authorized visitors can unlock it to enter.
Visitors cannot pass through the entrance unless a resident unlocks it for them. Since the system prevents entry by suspicious individuals or solicitors, it offers excellent security and is especially popular among people who prioritize safety.
Main Types and Features of Auto-Lock Systems
Auto-lock systems in condominiums can generally be divided into six main types:
・Common Key Type
This type uses the same key as the individual unit’s front door. With just one key, residents can unlock both the building entrance and their own door—keeping things simple. It is widely used, but if a previous resident made duplicate keys, there’s a risk of unauthorized entry.
・PIN Code Type
Residents unlock the door by entering a PIN code on a keypad. There’s no need to carry a key, and you won’t be locked out even if you forget it at home. However, there are risks such as someone watching you enter your code, or the system locking temporarily if the wrong code is entered repeatedly.

・Card Key Type
Residents unlock the entrance by swiping a card with magnetic data through a card reader. Because duplication is difficult, it offers excellent security. Cards are compact, but if they bend or become dirty, the reader may fail to recognize them.
・Contactless IC Type
Residents unlock the entrance by holding up a card key embedded with an IC chip. Recently, contactless IC cards have become more common than magnetic card keys. They are frequently installed in newer condominiums, which tend to have higher rent levels.
・Biometric Authentication Type (Fingerprint or Facial Recognition)
This system unlocks the door by verifying pre-registered fingerprints or facial data. There’s no need to carry keys or remember passwords. Although popular in luxury condominiums, recognition errors can occur due to factors like dry skin or masks.
・Smart Lock Type
Residents can unlock doors using a dedicated smartphone app. This system allows locking and unlocking with a smartphone, eliminating the need to carry keys or cards. It also offers convenient features such as checking lock status or operating remotely. However, it may not work smoothly if the phone battery is dead or network connectivity is poor.
Can Individual Residents Install an Auto-Lock System?
Installing an auto-lock system at a shared entrance is generally difficult for individual residents. This is because adding or upgrading an auto-lock system requires approval from the building’s management association. Installation involves construction and maintenance costs, which must be covered either by using the repair reserve fund or by contributions from residents.
In principle, individuals cannot carry out modifications to shared areas such as entrances on their own. What residents can do individually is install an auto-lock system for their own unit’s front door. To install or upgrade the system for the entire building, discussions and agreements among all residents are required.

Why Auto-Lock Condominiums Have an Advantage in Sales
When selling a condominium, both facilities and location play key roles in determining value. Among them, condominiums with auto-lock systems are often considered advantageous due to their enhanced security, which attracts potential buyers. Auto-lock systems prevent unauthorized entry and ensure resident safety. They are especially popular among single women and families with small children who prioritize security.
Even for older, pre-owned condominiums, properties equipped with auto-lock systems are often preferred. When compared with similar properties in the same area or price range, the presence of an auto-lock can become a decisive factor. It serves as a strong selling point that can raise the property’s market value.
Summary
Condominiums with auto-lock systems offer higher security and are easier to attract buyers, but having one does not guarantee a successful sale. Even if your property lacks an auto-lock system, other strengths can still increase its marketability.
