What type of locks exist on safes and which one should I choose?

There are several types of locks commonly used on safes. The choice of lock depends on your specific needs, the level of security required, and personal preferences.

types of safe locks


The 4 main types of locks are Key locks, Digital locks, Mechanical locks, and Biometric / Finger-scan locks. Almost all our safes come with a digital or key-locking option. Here are some common types of locks found on safes:

  1. Combination Locks: Combination locks require the user to enter a specific sequence of numbers or symbols to open the safe. They can be either mechanical or electronic. Mechanical combination locks have been used for a long time and are generally reliable. Electronic combination locks offer convenience and additional features such as multiple user codes and audit trails.
  2. Key Locks: Key locks operate with a traditional key that must be inserted and turned to unlock the safe. They are simple and reliable, but the security level depends on the quality of the lock and key. Key locks can be vulnerable to picking or unauthorized duplication of keys.
  3. Electronic Keypad Locks: Electronic keypad locks use a numeric or alphanumeric keypad for entry. They require the user to input a specific code to unlock the safe. These locks offer convenience and can have additional security features such as time-delayed access and multiple user codes. However, they rely on batteries and can be susceptible to tampering or electronic hacking.
  4. Biometric Locks: Biometric locks use fingerprints, retinas, or other biometric data for access. They offer convenience and eliminate the need for remembering codes or carrying keys. There is only 1 Biometric lock used in the UK industry currently, and is only suitable for certain high security safes. They are the least common lock type.

For most residential and commercial clients, we generally recommend a digital locking safe. The risk of having a key lock is that if you keep the key on your person, it may be lost or taken.  And if you keep it in a ‘secure place’ you will always have the risk of someone finding it. A key-locking safe is only as secure as the keys are. Key locking safes come with 2 keys as standard and additional keys can be requested at the time of placing an order. Digital locks can be considered more secure as you don’t have the risk of losing keys.

When choosing a lock for your safe, consider the following factors:

  1. Security Level: Determine the level of security you need based on the value of the items you plan to store in the safe. Higher security locks may be more expensive but offer better protection.
  2. Convenience: Consider the ease of use and convenience of the lock. Electronic locks and biometric locks provide quick access without the need for keys or remembering combinations.
  3. Reliability: Only choose a lock that is recommended for that particular safe. The locks and have been tested and fitted to comply with security standards. Changing these locks without speaking to a security professional may jeopardize the security of your safe.
  4. Budget: Set a budget and choose a lock that fits within your price range. Remember that higher security locks often come with a higher price tag.
  5. Additional Features: Consider any additional features you may need, such as time-delayed access, multiple user codes, or audit trail capabilities.

Ultimately, the choice of lock depends on your specific requirements and preferences. It’s advisable to consult with a professional locksmith or safe specialist who can provide personalized advice based on your needs.
