What is the process for rekeying an interchangeable core lock?

Rekeying an interchangeable core lock involves changing the combination of the lock so that it can be operated by a new set of keys. This process is often performed by locksmiths or security professionals. Here's a general overview of the steps involved in rekeying an interchangeable core lock:
1.Gather Tools and Supplies:
The locksmith will collect a variety of tools and supplies needed for the rekeying process. This may include a key decoder, pinning kit with different sizes of pins and springs, follower (a cylindrical tool used to remove the plug), plug holder (used to secure the plug during rekeying), new pins, springs, and new keys.
2.Remove the Core:
Using a control key that is specific to the interchangeable core system being worked on, the locksmith will insert the key into the lock and turn it to the control position. This allows the core to be extracted from the lock housing.
3.Disassemble the Core:
With the core removed, the locksmith will further disassemble it by removing the retainer clip or screw that holds the plug in place. The plug is then separated from the housing.
4.Decode the Key:
A key decoder is a specialized tool that helps the locksmith determine the pin heights or cuts needed for the new key. By inserting the control key into the decoder, the locksmith can obtain the precise configuration of the original key.
5.Remove Old Pins:
The locksmith will use a pinning tweezers or other suitable tool to carefully remove the old pins and springs from the plug. These pins correspond to the cuts on the old key.
6.Select New Pins:
Based on the decoded information, the locksmith will choose new pins and springs from the pinning kit. The new pins are selected to match the cuts of the new key.
7.Install New Pins:
Using the new pin heights obtained from the decoding process, the locksmith will insert the selected new pins and springs into the chambers of the plug. The pins are inserted one by one and positioned precisely.
8.Reassemble the Core:
Once the new pins are in place, the locksmith reassembles the core by carefully placing the plug back into the housing. The retainer clip or screw is used to secure the plug in place.
9.Insert Core into Lock Housing:
The rekeyed core is then inserted back into the lock housing, aligning it properly with the lock mechanism.
10.Test the New Key:
The locksmith tests the newly rekeyed lock using the new key. The key should smoothly turn the lock cylinder and operate the locking mechanism without any resistance or issues.
11.Adjust if Necessary:
If there are any problems with the lock's operation, the locksmith may need to make minor adjustments to the pin positions or recheck the pin heights to ensure proper alignment.
12.Cut Additional Keys:
Once the rekeying process is successful and the lock operates smoothly, the locksmith may cut additional keys to match the new key configuration. These keys will now work with the rekeyed lock.
13.Hand Over Keys:
The locksmith provides the newly rekeyed lock and the new keys to the owner or authorized personnel, completing the rekeying process and ensuring that the lock is secure and functional.
