Apartment Smart Locks

If you’re a renter and want to get a smart lock what do you do? Landlords don’t want you to change out the locks, they still need to get in with their own key. The answer is get a smart lock that retrofits to the deadbolt. Or you could call it an apartment smart lock.

Because these locks only replace the back of the dead bolt or just attach to the interior part of the deadbolt it requires no modifications to your door or the lock.

Using one of these apartment smart locks allows you to keep your existing key and use it in the event that the batteries are dead.

The drawback when using these types of smart locks is if your dead bolt is damaged or inferior it won’t replace that part of the deadbolt. For example if you want a more secure deadbolt than the one you currently have, these smart locks will not help with that. For that you would need to replace the whole dead bolt with one that is graded higher.

These locks make the most sense for renters. Installing these smart locks does not require the total removal of the existing deadbolt, just the part of the deadbolt that is on the inside of your house. One of them requires no modification to the existing deadbolt at all.

The benefit of these retrofit smart locks is that these are all easy to install, they can be removed with no damage to the existing deadbolt and all are capable of remote operation.

  1. Oh thank you so much for listing all of these smart locks! I just rent a new apartment, but the owner didn’t want to change or add more security to the doors. It’s just I’m a bit paranoid, so I feel safer when there are additional locks like this. Personally, I like the August Smart Lock one. Will it notify me if the door isn’t closed after several seconds? And if so, can I set how many seconds it should ring (or notify me)? Thanks

    1. Yes it will. August has DoorSense and it comes in 2 pieces, 1 for the door and 1 for the door frame. Once installed they can sense if they line up or not and will let you know through the app. 

  2. it didn’t cross my mind to have one of these fixed and how easily it can be installed. Having it will certainly give me peace of mind. I like the Friday Lock because I can easily manage it with my iPad. But having to remove the battery for recharging is not that ideal. I will look at the other options. Thanks for your recommendation. 

  3. I have seen some of these locks at friend’s places and have been curious. If I have one on my apartment, can the landlord still get in? I am a bit confused how they work.

    If I went away and the battery went flat on the smart lock, my key will still let me in, right? Do you get a warning when the battery is going flat? 

    Finally, which one do you recommend?



    1. Hi Peter, thanks for the questions. 

      The landlord can still get in. These locks only replace the interior part of a traditional deadbolt so the key will still work on the exterior deadbolt. And on the interior you just turn them to lock and unlock like you would with a regular deadbolt or use the smartphone app. 

      The key will still work regardless if the batteries run out or are still working. And you do get a warning on our phone when the batteries need changing.  

      I would recommend the August Smart Lock Pro. It’s just the best one, most reliable, better integrations with smart home devices, good customer service and really low fail rate.

  5. Smart locks and automatic locks can be useful for sure. I don’t come across smart locks such as this one very often, so I appreciate you asking the right questions here. This is an impressive array of smart locks. For me I like the Danalock V3. Thank you for such great information, well done!
