I have covered smart locks quite a lot in the past, it is an area of smart home technology I have always loved the thought of but it has never seemed to gain much traction in the mainstream market, unlike lighting or home heating.

I have already reviewed the Yale Conexis L1 Smart Door Lock and the Nuki Smart Lock. Both are excellent in their own right, but both have a few niggles that the Ultion Smart Lock potentially addresses.

Smart Lock popularity in the UK

One of the significant issues in the UK has been lack of compatibility with established brands such as August due to the less secure design that American doors work on.

Smart lock brands like August work on single cylinder deadbolts with just the deadbolt locking the door into place. This works well for smart locks because the mechanism can turn freely. With the European style multi-point system, we typically need to raise the handle to place the multi-point locks into place. This makes smart locks a little harder to be smart.

Smart lock options for multi-point doors in the UK

While there are plenty of options on Amazon, many of them are not for multi-point doors, and often from unknown brands.

To date there are only a few smart locks worth considering (in my option) including:

Ultion Smart vs Danalock

Ultion Smart Lock Review – The best smart home lock I have reviewed to date (All in one Z-Wave Danalock by Brisant Secure) 1

Basically, the Ultion Smart is a 3rd party implementation of the Danalock. They have taken the Danalock V3 and integrated it into the door handle. Then as part of the price, Ultion includes one of their own cylinders which are extremely high security being bump and snap proof. The cylinder itself comes with a £1000 guarantee if a burglar breaks it.

Smart Lock Concerns – Hacking, dead battery, and electrical failure

There are two significant concerns for people when investing in a smart lock: hacking and general failure.

In my opinion, hacking is not a serious concern for the average person. It will generally be easy to bump a lock, snap it, or just smash a window. All of which require considerably less skill than hacking and will almost always be faster.

In the case of Ultion/Danalock they use an advanced encryption method for transferring data (AES 256). By default, the lock is Bluetooth only, so you also need to be close by to it. Competing brands all offer similar levels of security.

The other issue is what happens if the lock fails somehow. This can be a malfunction of the lock side, a dead battery, or just user error for example if you get logged out of the app and don’t know the password or forget your key tag.

Yale and Netatmo are electronic only, so potentially are more prone to problems. Both brands have a battery backup solution, the Yale one is a little cumbersome, but it will work. Both brands have physical NFC based keys, so in theory, if you have that you can always get in.

Again, in my opinion, both Nuki and Danalock/Ultion offer a superior (and simpler) solution. They still allow you to use your physical key.

In reality, I doubt there is much difference in the odds of being locked out with Yale/Netamo vs Ultion/Danalock/Nuki but having a physical key helps with the mental transition of moving to a smart lock.
