Samsung products have been around for decades. They are a well known electronics manufacturer based in South Korea. You’re probably aware of their TVs, computers, phones and appliances. Samsung has been making big moves in the digital door lock market as well. Their locks look sleek and clean and might remind you of their smartphones. The Samsung SHS-3321 digital door lock does not have a keyway, so this is a true keyless deadbolt.
This lock is opened with a code or a radio frequency identification(RFID) card. There is no hole for a key making this a pick and bump proof lock. It also reduces the ways someone might use to try to get in.
The RFID information can be programmed to be on a keyfob or a sticker for the back of your phone. The Samsung sticky seems like a more obvious choice. People are more likely to lose or misplace their key and not their phone. And it makes more sense for active people who don’t like to have a bunch of keys in their pocket on a walk or run.
The installation of this Samsung digital door lock is pretty straightforward. It fits in the existing cutout of your door and has an adjustable latch so whether your backset is 2 3/8″ or 2 3/4″ this lock will work for you. The wires on the lock are a little long so you need to take care and not pinch them when screwing the back plates down. This lock also comes with a magnetic door sensor that is used for the auto locking feature. It is in 2 parts, one part next to the lock and the other attaches to the door frame.
There are two ways to unlock Samsung’s digital door lock – access code or RFID keyfob. Or if you want the lock to be even more secure you can turn on the double factor authentication and the lock will require both. The code can be anywhere from 4 to 12 numbers and it will accept up to 71 access codes.
The lock also has a random code generator that requires you to touch two random numbers before your actual code. This is to prevent lookie-loos from seeing you input your code and prevent anyone guessing the code by looking for fingerprint smudges. If you’re using the RFID keyfob, it just has to be close to the lock body for the lock to read it.

Even though there is not a keyway for a physical key you’ll never be locked out even if the 4 AA batteries run out. This is because there are contacts on the side of the lock for a 9 volt battery that will give enough power to allow you to enter your credentials for access. The batteries will last about 10 months under normal use. There is also an audible warning that lets you know when it’s time to change them out.
The adjustable length latch allows this lock to be used in residential or commercial applications. And since the lock allows for 71 different user codes a small company could give a different code to every employee. Then if an employee does leave, the deletion of that employee’s code is easy and there would be no need to change the rest of the codes, reducing time and effort spent reissuing codes.
I actually used to work at a small company that gave a key to every employee. The problem with that was every time an employee moved on the lock had to be rekeyed. This lock would make much more sense in that situation.
