Key code

Types of key codes

A key code is a sequence of letters and numbers that can be used to make or duplicate a key. Different types of key codes are as follows.

• Edge codes

  Edge codes are found on the edges of keys. They have a series of numbers and letters that indicate the key's cut depth and the order of cuts. This information helps locksmiths make accurate duplicates of keys. Edge codes are sometimes called keyway codes or key blank codes.

• Blind codes

  Blind codes are used when the exact key code cannot be determined without the original key. A locksmith uses a set of key cutting machines that correspond to the blind code's specifications. The locksmith then tests the newly cut keys in the lock until one key works. Blind codes are helpful in situations where key code information is incomplete or when the key is not available for direct measurement.

• Manufacturer codes

  Some key codes are specific to key code system manufacturers. These codes are used in proprietary key cutting and key management systems. They often combine elements from various key code standards, customized to meet specific security needs. Manufacturer codes are usually kept secret and only used with the owner's permission.

• Security codes

  Security codes are used in electronic keys and smart keys. They are complex and change frequently to prevent unauthorized duplication or access. Security codes provide an additional layer of security beyond physical key cutting.

Specifications and Maintenance of Key Codes

• Regular Usage

  It is important to regularly use all copies of the key code, including the spare ones. This helps to ensure that they continue to work properly. If any copy is not used for a long time, it may stop working.

• Checking Security

  Users should periodically check the security level of their key codes. They can contact the locksmith or place that issued the key code to see if it is still considered secure. Security standards can change over time.

• Physical Condition

  Key code users should always inspect the physical condition of their key codes. They should look for any signs of damage, such as cracks or peeling. If they notice any problems, the key code should be replaced right away.

• Authorized Personnel

  Only authorized people should have access to the key code. Users should limit who knows the code and who can use the keys. This helps prevent unauthorized use.

• Key Usage

  Users should only use the keys for their intended purposes as specified by the issuing authority. For example, if a key is for office doors, it should not be used for personal locks. Misuse of keys can compromise security.

• Regular Maintenance

  Users should perform regular maintenance on key-related hardware, such as locks. This includes activities like lubricating locks, ensuring they function smoothly, and preventing key wear and tear.

• Monitoring Access

  Where applicable, users should periodically review access logs or records related to the key code. This helps them track who has accessed areas secured by the key code, enhancing accountability.

How to choose key codes

Here are some tips for choosing key codes:

• Security

  Consider the level of security that users will need. Standard 5-pin or 6-pin locks are adequate for low-security areas. More complex locks like disc detainer or electronic key codes offer higher security. Think about how vulnerable the area is and choose accordingly.

• Compatibility

  Ensure that the key codes chosen will be compatible with the locks that will be installed. Different locks require specific key designs. Don't assume that a key code will work with a particular lock brand - double-check compatibility before purchasing.

• Availability

  Some key codes are more readily available than others. It may take time to order key blanks or key cutting machines for less common codes. For fast turnaround, select key codes that are widely used and easily sourced.

• Complexity

  Consider how complex the keys will be to cut. Some codes require specialized equipment or training to cut correctly. If a local locksmith or hardware store cannot cut the keys, it could cause problems later. Choose codes that are relatively simple to ensure that key duplication is convenient.

• Cost

  Higher-security key codes usually have a higher upfront cost due to the price of key blanks and cutting equipment. Weigh this against the level of security provided. Sometimes, spending a little more on high-security keys can save money by preventing theft. Evaluate costs but choose primarily based on needs.

How to DIY and Replace Key Code

• Read the owner's manual

  The first step to DIY replace key codes is reading the owner's manuals. This is because different vehicles have different key code systems. The manual will provide detailed information on how to replace the key code.

• Obtain a new key code

  After reading the manual, the next step is to get a new key code. To do this, contact the car dealer or locksmith. They will provide a key code that matches the original key code.

• Use the key code to program the key

  Once a new key is obtained, it is important to use the key code to program the new key. The key code provides instructions on programming the key to match the car's ignition system. This step is very important as it makes sure the new key works on the ignition system.

• Test the new key

  After programming, it is important to test the new key. Turn on the ignition system to see if the new key works. If it does not work, repeat the programming steps again. Make sure the key code is correctly programmed.
