A smart key lock, specifically referring to Kwikset's SmartKey Re-key Technology, works by allowing you to re-key your lock in seconds without removing it from the door, eliminating the risk of old keys still working after construction or key loss.
The core concept behind SmartKey technology lies in a side-locking bar mechanism rather than traditional pins and tumblers. This allows for easy re-keying by using a special tool and the new key you want to use.
Here's a simplified explanation:
- Existing Key: The lock is initially keyed to a specific key.
- Re-keying Tool: You insert the existing key and then insert the SmartKey tool into a small slot on the lock.
- Turn and Remove: You turn the existing key a specific amount (as per the manufacturer's instructions) and remove both the key and the tool. This disengages the existing lock configuration.
- New Key Insertion: You then insert the new key you want to use into the lock. The internal mechanism "learns" the new key's configuration.
- Lock is Re-keyed: The lock is now keyed to the new key, and the old key will no longer work.
In essence, the SmartKey technology provides a convenient and secure method to re-key your locks, allowing you to quickly change the key needed to open them without the need for a locksmith or replacing the entire lock. This is achieved through a unique side-locking bar mechanism that can be easily reset with the SmartKey tool and a new key.
