Can Car Keys Be Self-Duplicated?

[DerekFitz]

Yes, they can. If you have a spare key, it can be used normally. Additional information: 1. Car keys are relatively more secure and advanced compared to ordinary house keys. To duplicate a remote key, the 4S shop needs to match the new key with a "code" from the original car. 2. After the car key is matched, the new key can be activated, and the lost key will become invalid immediately. 3. Duplicating car keys is relatively expensive, depending on the car model and brand. 4. Many cars are equipped with electronic key locks, which are mostly applied to ignition locks, further enhancing the functionality and anti-theft effect of the car's electronic anti-theft system. Electronic key locks can be divided into two categories: resistive electronic key locks and coded electronic key locks. The working principles of these two types of electronic key locks are exactly the same, both using a codec circuit.
