Pros and cons

According to our door lock expert
  • The lock replaces your current cylinder, which makes it suitable for almost all front doors.
  • Thanks to geofencing, the smart door lock knows exactly where you are and will the moment you're close by.
  • Without a smartphone, the lock is easy to open with your own PIN code.
  • This door lock is suitable for cylinders with an interior of 30 to 35mm and an exterior of 50 to 65mm, so check whether the door lock fits in your front door.
  • You need a Bold Connect bridge to control the door lock from anywhere via the internet.
  • You always have to close the lock manually, which means you can't lock the door later if you forget to do so.

Very good smart lock, just not for a holiday home

  • Easy to install
  • You can leave the door with empty pockets, no key or mobile needed
  • Solid construction
  • Not suitable for a b&b or holiday with self check-in

Before I bought the lock I had contact with the helpdesk. That was nice. They responded quickly and gave clear answers. For example, I discussed with the lock whether the lock is suitable for self check-in. It was already clear to me that a user had to install the app and create an account or that the guest could enter a PIN.
Installation was easy, I had everything up and running quickly and after some instruction the children could also open the door by turning the knob. Automatic opening also works well, you must have been more than 200 meters from your door.
Giving guests access is simple, the app then sends a link by text message to install the app. However, this process is too extensive for a visitor to a holiday home who is not familiar with this lock. You must enter both your mobile number and your email and both must be verified. In addition, a password has to be created and a few choices have to be made for location determination, etc. Not surprising if you are going to use this lock as a regular, but for occasionally too complicated. It raises too many questions. Alternatively, there is the PIN code. I've had a number of people try the pin code after reading a written instruction and showing them an instructional movie from bold and no one got it right the first time. It's not nice if you can't open the door of your holiday home after a long journey. A lock that works with a code panel is much more convenient.

The required app is already a drama.

  • Looks modern
  • SKG3
  • Privacy: Bold requires a lot of personal data to operate the product

The App is installed in no time, but you then receive a whole list of mandatory registrations to Bold, including your exact location provision. This really bothers us that for a personal item like a lock you have to share so much of your personal information before you can use a product. In addition, if you want to share the product with more people, they have to go through the same steps and that is simply not reasonable. Product returned unopened and looking for another product without mandatory consultation of your personal data. Your door may be SKG3 locked, but your personal data is in the hands of someone else, otherwise the product is unusable.

Very nice lock with sleek user-friendly app. No more keys you get used to really quickly. The backup PIN is an invention. Practice a few times, but after that it works fine. Please measure the size of your cylinder before ordering. The one where I saw the lock needed a longer Bold cylinder, the 33 fit me exactly.
