Review: Good quality, easy to use and install Smart Lock - I bought this Smart Lock for a Medical Office, it replaces an expensive electric strike system/proximity cards If you follow the supplied instructions the lock is relatively easy to install and it may take 60-90 minutes for the full installation. There 2 little issues I dont like: a) Batteries: Depending on use batteries may not last long. I recommend buying a set of 8 rechargeable batteries so you can alternate b) There is a voice notification every time it locks/unlocks the door. I have not found a way to disable this annoying feature. Besides these 2 things I strongly recommend this smart lock. It is easy to use, inexpensive and you can program contactless Fobs to lock/unlock the door. ## Features - Key Unlock ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IVJLAVY | | Additional Features | Key Unlock | | Brand | HAIFUAN | | Brand Name | HAIFUAN | | Control Method | Remote | | Controller Type | Remote Control | | Customer Reviews | 4.1 out of 5 stars 659 Reviews | | Included Components | Key | | Item Dimensions | 16.2 x 7.5 x 15.5 Centimeters | | Item Weight | 2.14 kg | | Item dimensions L x W x H | 16.2 x 7.5 x 15.5 Centimeters | | Lock Type | Key Lock | | Manufacturer | HAIFUAN | | Manufacturer Part Number | HFAD6300 | | Material | Metal | | Material Type | Metal | | Model Number | HFAD6300 | | Number of Pieces | 2, 4 | | Recommended Uses For Product | security | | Special Feature | Key Unlock | | Style Name | Modern | | UPC | 713893602571 | ## Product Details - **Brand:** HAIFUAN - **Item dimensions L x W x H:** 6.37 x 2.95 x 6.1 inches - **Lock Type:** Keypad - **Material:** Metal - **Special Feature:** Keyless ## Images ![Digital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible - Image 1](https://m.media-amazon.com/images/I/71RlErTHtmL.jpg) ![Digital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible - Image 2](https://m.media-amazon.com/images/I/61-HRSOtolL.jpg) ![Digital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible - Image 3](https://m.media-amazon.com/images/I/61o243BpTHL.jpg) ![Digital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible - Image 4](https://m.media-amazon.com/images/I/615Igyd4gGL.jpg) ![Digital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible - Image 5](https://m.media-amazon.com/images/I/61RcVqDW6PL.jpg) ## Questions & Answers **Q: where can i get additional "cards" or remote control?** A: I bought several "Samsung Door Lock RF Key Card Stick Card for 2920/5120/6020/P718/P910/DP728/DP920 Smart Tag Card" and they work without any issues.
