Door Code Lock

Our client had a range of mechanical door code locks and wanted to expand their range by adding electronic locks with RFID and keypad access control.

The client had no experience with electronic locks, needed a battery powered solution so low power was important. The housing for the lock was made of metal so reading RFID cards was difficult.


The solution was a single PCB solution with a keypad and an RFID reader. The locking mechanism was motorised to keep power consumption low (compared to a solenoid). We designed the PCB and software for the product.


Having an electronic lock allows easier and more flexible code management (eg. different codes for different people). Also, using RFID allows cards to be issues which prevents codes being seen while being entered.
