Connection Standards and Smart Home Controller Options

Kwikset SmartCode 888 Smart Lock can connect to hubs which support z-wave technology. If you have Samsung Smartthings Hub on your home, you can easily setup this lock to your system and control over the app. Echo Dot is another option that you can choose to use but it does not support direct connection to lock so first you must connect your Echo Dot to Samsung Smartthings Hub.You can also use it with your z-wave compatible Google Home Hub but it requires more effort than Samsung Smartthings Hub. If you have a Ring Alarm Home Security System installed at your house, you can lock/unlock your door over the Ring app too.

Keypad Of Kwikset SmartCode 888 Smart Lock

Keypad is a widely used product for lock industry and it is not different for smart lock part too. It is more preferred than fingerprint readers because of advantages when they are compared. Kwikset SmartCode 888 Smart Lock has a little differently designed 5 button keypad with an additional button for locking. At the first looking you might be confused on how to use it but you don’t need to worry.

Keypad has Backlit on the buttons but it is not very bright so you will probably feel as it should be more bright but it is still much better than having no Backlit. If you want to activate backlight you can press the lock button in the middle of the keypad before you enter your password. Before purchasing please make sure that your door has backset either 2-3/8 or 2-3/4 inches wide and hole in door is either 2-1/8 or 1-1/2 inches wide. Otherwise it will not fit to your door.

Using the keypad is very simple. To unlock your door all you have to do is to enter your password. Your code must be 4 to 8 digits. If you want to lock the door just press the lock button in the middle of they keypad. You can generate up to 30 user passwords and 1 master password for your needs.

Default master code is “0000” and default unlock code is “1234” so please make sure you changed these codes as your firs step. You would not want any unexpected visitors on your door. Programming the lock is pretty easy when compared to Kwikset 913 Smartcode Electronic Deadbolt. Window on the interior cover is locked by default but you can remove the security screw on it so it will be unlocked.

If you choose to keep the window unlocked, you can remove the cover just by sliding up and access programming buttons. You will be ready to add/delete new codes at this point. You can also use the app of your connected smart hub to add/delete users. There is also an option for one time acccess so you can create codes that will not work after one time usage.

Bump Key Protection

As you may already know Bump Key ( an attack technique used to defeat conventional pin & tumbler locks) is very widely used method to open the doors. Kwikset SmartCode 888 Smart Lock has patented side locking bar technology which offers bump guard protection on the lock. This means you don’t need to worry about Bump Key technique on your door. Since it has a cool protection it will not be opened by any bump keys.

This feature is very helpful especially if you have some other locks which are using asingle key. You can simply add this key to your lock and use it. It has many usage areas which will save your life. Please note that this technology is technology is compatible with Kwikset (KW1) keyway so make sure you have correct type of key to rekey.

Auto Lock

Auto lock feature is a life saver for most of the lock users. We all can forget to lock our doors. This feature is disabled by Kwikset as default with timer set to 30 seconds. You have option to change this timer to 30 – 180 seconds after enabling auto lock. If you enable this feature your lock will lock the door after 30 – 180 seconds passes over unlocking. If you want to activate it you have to open the cover of interior unit (not keypad) by sliding up the cover (if it is not locked by security screw which we stated above).For the next steps please follow the instructions we shared below.

Make sure that you closed the door completely so that auto lock can do it’s job. Otherwise it will not be able to lock the door and try to lock 2 times and give up.

Battery Life of Kwikset SmartCode 888 Smart Lock

Kwikset SmartCode 888 Smart Lock has a satisfactory performance for battery life. System is powered by 4 x AA batteries which are not included in the package. We suggest you to buy Duracell batteries for the longest usage time. Kwikset predicts battery life between 6 – 12 months. This prediction is almost perfect because you will really have minumum of 6 months of usage if you are not using your smart lock under very low temperatures. If you don’t want to spend money on changing batteries you can simply choose to have rechargable batteries but in our opinion you won’t need this.

Unlike our previously reviewed product Kwikset 913 Smartcode Electronic Deadbolt, this smart lock has low battery indicator. It starts to flash red light and gives you a warning tone when your battery starts to be low so you will know when you should start worrying about changing your batteries. Even if you forget to change your batteries you can still unlock your door by using your key.

Installation process of Kwikset SmartCode 888 Smart Lock

Kwikset SmartCode 888 Smart Lock has very easy installation process which does not require and special skills. Depending on your experiences you can expect to install this product between 10 – 20 minutes. In some positions it can take a little longer as you will maybe need some drilling on the door but this is still not taking too much time.

You will need a ruler and Phillips Head Screwdriver for the whole process but in some situations depending on your door you may need a hummer and wood block. User manual clearly explains all the steps with details so you should not worry about installation process.
