Lishi DAT17 is a type of lock pick tool that can be used to open some car locks. It is designed to work with locks that have a DAT17 keyway, which is common in some Subaru models. Lishi DAT17 has two functions: picking and decoding. Picking means using the tool to manipulate the pins inside the lock until it opens. Decoding means using the tool to read the bitting code of the key, which can be used to make a duplicate key. Lishi DAT17 is made of stainless steel and has a comfortable handle.
