You will use a Decoder if you offer the service to cut Auto Keys. Some Auto keyways require the lock to be in the open position (i.e. unlocked) before you can decode the key. Others can be decoded in the locked position (these are clearly marked).
 

For Lishi Decoders there are a number of blank make up keys are available.


LISHI DECODERS: now suppose someone has lost their keys, or had them stolen. The requirement for the auto locksmith is now to find the code of the key from the lock, and then cut a key. This is called DECODING the lock. The process requires a tool finding every wafer in the lock and determining the size of the wafer. This is what a LISHI DECODER does. 

 Some Locks can be DECODED whilst they are still locked. In these instances an Auto locksmith needs simply to decode the lock, cut a key and then use the key to open the lock. Other Locks need to be opened first before the lock can be decoded. 

To DECODE locks the auto locksmith will need to be able to offer a key cutting service.
