## Customer Reviews

### ⭐ 







  
  
    Key didn't fit lock
  

*by T***M on Reviewed in Australia on 4 February 2022*

I purchased this item and fitted it to my back gate. After installation I discovered that they key supplied with the lock did not in fact fit it, requiring me to remove the lock (and leaving a large hole in the gate) and ship it back to the US for a refund several weeks later. This just shouldn't happen.

### ⭐⭐⭐⭐ 







  
  
    Works well.
  

*by J***S on Reviewed in Canada on 20 December 2020*

Works well gets a little sticky in cold weather.

### ⭐⭐ 







  
  
    Does not stay locked unless you replace internal spring
  

*by N***M on Reviewed in the United States on 21 June 2021*

I was skeptical of other reviews that said the lock did not stay locked and would unlatch when “jiggled.” I was wrong. About half the time, the locking pin just does not fully engage and so it unlocks itself if jostled or disturbed. That makes it basically useless out of the box.I was able to fix the lock by replacing the spring with a stronger one purchased separately. It now works perfectly well. The overall design/mounting configuration of the lock was the only one that would work for our purposes so I’m glad I found a work around. But unless you’re willing to rehab the lock don’t buy it.The way I fixed it was to open up the lock by unscrewing the back plate, and then remove the small locking pin. (The locking pin can be made to falls out of a little window in the metal casing if you engage the pin fully; you only really need to replace the spring on one of the pins—depends on whether you’re using it in right-handed or left-handed configuration.) I then replaced the compression spring on the locking pin with a stronger/somewhat longer one that was included in a “spring assortment kit” I had previously bought elsewhere—also available on Amazon here: Everbilt Spring Assortment Kit (84-Pack) https://www.amazon.com/dp/B00FI6XHV0/ref=cm_sw_r_cp_api_glt_fabc_5NJ0K39WKXC02RVZ387ROnce the spring was replaced it worked great. The stronger spring makes sure that the locking pin properly seats every time. It now locks tightly and does not jiggle loose ever. The fact that the company is manufacturing and selling this with a clearly deficient spring is ridiculous. The product is defective as sold and they should take it off the market if they refuse to sell it with the appropriately-tensioned spring.
