Arduino DIY – How to Make a “Binary” Keyless Entry System using Servo Motors!


Well, I have been busy yesterday and today with bunch of clients working on various different projects.

Anyways, here’s a great DIY on how to make your own keyless entry system using Arduino and servos.

Of course, the best part about the keyless entry system is that it uses “binary” code in which the user must “thumb”, similar to Morse code system.

According to the person who made it, this system is actually a lot more secure than numbers:

From personal experience (mostly my roommate has absolutely no rhythm), the pattern key could probably contain about 6 different lengths. Thus a key with length n will have 6^n possible combinations. To make the system more secure, there is no indication that an input is wrong; an attacker has no idea how long the key is.

Great DIY, this might be a great new way for Keyless Door Entry makers to implement, a binary key.
