The lock arrived this afternoon, and I installed this evening. Installation would have gone much easier if they had included instructions in ENGLISH!  The instruction sheet had steps 1 and 2 in English, the balance in Spanish! Thank goodness for the online instructions! Once installed, seems to work well. The only issue is (and I have seen this in other reviews) the keypad does NOT light up. Makes it a bit more difficult in the dark. Overall, though, it's a solid product. Have now done the re-key yet, but I hope it works well!
