  1. Great price, solid parts

    Posted by Unknown on 18th Aug 2019

    Really needed just the lock but it was less expensive to buy the whole kit. It was basically just a swap over because the lock I had was temperamental and would stick every once in a while. The instructions that came with the kit were great except for when it came time to change the combination. Had to go to the manufacturer website to get an updated instruction sheet. But I will buy again when the need arises without hesitation.

  2. I’m happy
