    I was looking online for a push button lock for a backyard gate. I thought I would buy a different brand, but called to ask a few questions. The representative told me the Simplex lock was the right one, because I could easily change the code. I bought the Simplex back to back locks, my fence contractor installed an iron gate and the locks. I was able to set the access codes in less then 5 minutes.
