Please use the Shopping Cart to group your items together so you can make one payment and pay one shipping charge. From experience I do know that at least some of the Streamline wall boxes use the type of Chicago lock that accepts the key profile I am offering in this listing. This listing is for one key with the number seen in the photo and noted in the title of this listing. The second photo shows the opposite side of this type of key and the third photo shows the type of lock that accepts such a key.
Thank You.
If you need more than one of this key number let me know before you buy and I will revise the inventory number if I have more than one available.
