![]() The sensor emits IR light, and based on the amount of light reflected from the segmented wheel, the microcontroller is then able to determine how far the locking bolt has moved. The sensor is comprised of an IR emitter and a photodiode. The optical sensor used is the EE-SY193 by Omron. In order to determine the position of the bolt, the system uses a reflective wheel and an optical sensor. The reflective disk mounted to the gearbox that is used to determine the position of the locking bolt The 130 sized motor that is attached to the gearbox, notice the slots for the metal contacts Optical Encoder The motor, which is attached to the gearing mechanism, gets plugged into the Metal contacts (MJ1 and MJ2). Kwikset keypad deadbolt driver#The motor driver comprised of 6 transistors and several resistors The motor is controlled by a motor driver comprised of 6 discrete transistors. The motorized deadbolt is powered by a 130 size DC motor. The wiring harness that connects the keypad to the other electronics Motor Driver These terminate in a 14 pin keyed connector. On the back of the circuit, two wiring harness are soldered in place. The keypad PCB is fairly unpopulated the only components that are on the circuit board are 4 SMD LEDs and 6 dome switches. The keypad is comprised of a cast zinc body, a rubber keypad, and a PCB. The first component of the deadbolt we'll look at is the keypad. For more information on the unique mechanics of the Kwikset SmartKey Lock used in this deadbolt, take a look here. This article will look at the electronics in the lock the mechanical aspects of the lock are pretty neat as well. Kwikset SmartCode deadbolt Lock mounted to a door In this week’s teardown Tuesday, we will take a look at what makes this lock work. Kwikset keypad deadbolt code#The Kwikset Smart Code deadbolt lock is a residential lock with an integrated motor and keypad so a pin code can be used in placed of the key. Maximum 1 minute required.Want to know what's inside a Kwikset SmartCode lock? Just slide up the cover on the interior unit and change the batteries. Even if you forget to change them you can still use your key to unlock the door if it is near you.Ĭhanging the batteries is very simple. You should change them as soon as possible to prevent battery drain. Kwikset button flashes red 10 times with 10 beeps to inform you about low battery. So we can’t say exact timing but you can expect to change your batteries around 6-8 months with an average usage frequency. It will give you low battery error if you try.īattery life may change significantly depending on the factors as weather conditions, usage frequency, battery quality, condition of the door, auto lock. Unfortunately, you can not use rechargable batteries. We suggest you to buy Duracell batteries for a longer performance. These batteries are not included in the package.battery life. Kwikset 264 Contemporary Keypad Deadbolt requires 4 x AA Alkaline batteries to operate. After you set your desired time it will lock your door automatically after that time passes over the last unlocking operation.īattery Life of Kwikset 264 Contemporary Keypad It is possible to set the timer to 10-99 seconds. Once you enable it, it will be set to 30 seconds. It is disabled by default so you should enable it. This feature is very useful for the cases you forgot to lock the door or if you just want to automate it. Auto LockĪuto lock is also presented to us with this keypad deadbolt. When you press it, it will start locking. This button is also used to lock the door. We suggest you to activate it by pressing the button with Kwikset logo at the top. Kwikset 264 Contemporary Keypad Deadbolt has a backlit which is activated by pressing any button. It is very easy to add/delete user codes. Second thing should be to delete the default user code which is 1234. Changing the default programming code should be the first thing you have to do to prevent unwanted attempts on your door. Programming is made by entering the programming code which is 0000 by default. You can use this code for some services as dogwalkers or any services you take at home. When someone uses that code it will automatically deleted and will not work again. One time usage code is very useful feature. It can be programmed to hold 6 user codes + 1 one time usage code with 4 to 10 digits. When you hold the keypad in your hands you can easily feel the quality. Keypad is made of metal material with high quality finish. ![]()
