Simple, works just fine

It’s simply 3M double stick foam tape, but it’s pre-cut to the correct shape and size. If your sesame lock fell off or is falling off (a dog pulled mine off), just order adhesive (it’s inexpensive) which will arrive in a couple of days, peel off the old one and stick on the new. Reset the lock positions in the app if you have to, but overall takes less than a minute.

I didn’t read the description well but it was a nice surprise when I realized it came as a set of 2.
