Can S1 be used in my lock?

Step 1. Check the picture below to see if your lock type is included.

Note: For type 1-4 (the cyan part), S1 smart lock can be used directly without any optional add-on.

For type 5-6 (the gray part), the optional add-on is needed. A 5572 lock body is needed for type 5. A 5572 lock body and a front panel are needed for type 6.

If you are not sure about the compatibility or your lock type, you can also contact us at support@yeeuu.com for help.
