![]() ![]() The TI MSP430 microcontroller in a 64 pin exposed pad package Expansion Slot This is a 64 pin, 16-bit, microcontroller designed for low power applications. It's difficult to tell from the images due to the conformal coating, but the SmartCode Lock is controlled by a TI MSP430F5324 microcontroller. The small Omron IR optical sensor Microcontroller 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. It does not store any personal data.Want to know what's inside a Kwikset SmartCode lock?
