The exact figures behind the SF Slim Series, because a lock is a promise you should be able to check.
The questions everyone asks, answered plainly, because peace of mind starts before you buy.
Not all of them. On most of them, say 90%. The main ones that are not compatible are those multi-points with offset spindles. It means their handles are not aligned! For these locks, the best alternative is Simpled smart cylinders.
Normally, this smart lock doesn't come with a gateway. You need to add that to the basket. It's good to know that Without Gateway, you can still: See who access the lock with their smartphone Share keys with your family, friends, maid or dog walker Open your lock using your smartphone or smartwatch Limit other's access or even delete theirs With Gateway, you will be able to: Open your lock from anywhere Remotely read the lock operation, including fingerprint, tags, password Use it with your Alexa Add to Cart Only £56.00
For security purposes, our physical keys are designed unique to your lock ID, and we do not have spares of their respective physical keys. We recommend keeping a key with a trusted family member from the first day. The lock can still be unlocked via other means based on your lock model, i.e. smartphone unlock, fingerprints, pin codes, etc
There are two solutions: Physical Keys Physical keys are provided together with Simpled smart locks, which ensures that you will still be able to enter the house mechanically even if its batteries run out. It is strongly recommended to keep at least one spare key on you or a family at all times for such situations. USB Input Also, when the physical key is not available, there is a USB input on the bottom part of the smart locks (besides the key input) that enables you to connect a power bank to wake up the lock and unlock it.
Simpled locks come with an imaginary PIN code feature that allows you to enter other digits before/after your actual PIN. This is optional but will help to deter hackers and prevent your PIN code from being exposed. Also, with the security lockout mode, it is even more difficult to guess your PIN code.
No, only the outside panel is weatherproof, The inside panel is not weatherproof and it is recommended to use it indoors to prevent damage from exposure to moisture or water.
