It seems like you're asking about keys for locks with different sizes. In the context of locks, "chabi" might refer to a key, and "double 8mm, 9mm" could refer to the size or type of the key. Typically, keys are made to fit specific locks, and their size and shape are unique to the lock they are designed for.
If you need a key for a lock, you should contact a locksmith or the manufacturer of the lock to get the correct key. They will be able to provide you with the key that matches your specific lock. If you have a key that you need to duplicate, a locksmith can also help you with key duplication services.
