Gimdow Retrofit Smart Lock – Easy to Install/Configure Universal Smart Lock

If you’re considering buying new smart door locks for your home, then the Gimdow Retrofit Smart Lock would be a great choice.

This smart door lock is designed to fit most existing door locks and installing it is also very simple. Just peel off the mounting plate’s protection layer and stick it to the back of your door.

The smart door locks are also protected, and its wireless touchscreen keypad works via encrypted Bluetooth. This way you can create and share temporary virtual keys with anyone you trust, such as a babysitter, pet sitter, family, friends and Airbnb guests.

Let’s take a detailed look at the Gimdow Smart Lock, and check out what it has to offer.


The Gimdow Smart Lock’s main body – the lock mechanism itself – features a very solid build. This smart lock features a unique design that allows it to work with most American and European door locks, including both Fission Deadbolt Door Locks and Clinder (Conjoined) Door Locks.

The lock also comes with an included wireless touchscreen keypad that’s installed on the outer side of the door. The keypad works via encrypted Bluetooth by communicating with the Smartphone App to let people open the locked door with a simple code or tap, while still supporting the original keys too.

For the keypad, just use the included hex key (screwdriver) to open it up and place the other 2 AA batteries inside.



Installing the Gimdow Smart Lock is extremely easy. The process is both simple and quick, and should only take you around 10 minutes.

Pick the corresponding mounting plate (holder) that best fits your door lock (American Doors or European Doors), peel off the protection film and apply some pressure to stick it to the back side your door. The included mounting plates (holders) come with durable, but removable adhesive that’s protected by an easy-to-peel protection film.

After that, attach the Gimdow’s main part (the lock’s body) to the mounting plane, then a knob attachment (clamp), and finally the attachable circular knob on top of it. Then just rotate the knob a few times to check if you mounted the lock precisely.

Lastly, install/attach the included smart keypad at the front side (opposite side) of your door by applying a low/medium amount of pressure. And that’s it, an easy and quick installation and you’ll be ready to use it.


Configuring the Gimdow Smart Lock is also quite simple. Just download and install the App on your Smartphone, select what type of lock (Fission (Deadbolt) or Clinder (Conjoined) Door Locks), and turn the knob once (as the App requests) to finish the Bluetooth Pairing and configure/calibrate the lock.

Then give the lock’s keypad (Bluetooth device) a Bluetooth nametag for future identification, test both Lock and Unlock actions via the Smartphone App, and you’re all done.


3-in-1 Entry

The Gimdow Smart Lock is the ultimate smart lock. With this system you can have multiple entry ways that ensure you never get locked outside again.

You’ll be able to open whatever door you install the smart lock in via the Smartphone App, with a keypad code (configurable), or by using your old mechanical key.

Anti-Peep Passcode Reading

The Gimdow Smart Lock also features smart reading technology, allowing for Anti-Peep Passcode. This basically means that if anyone’s watching you while you enter your digit code via the keypad you can add some random numbers first without any worries, then all your code’s digits, and then add some more extra random numbers at the end.

Then after waiting just a couple of seconds your keypad will analyze the sequence and find the matching password that was previously configured, unlock the lock, and allow you to open the door.

Full Access Control & History Logs

By using the Smartphone App you’ll be able to control the lock from wherever you are. Not only that but you’ll also be able to manage multiple users and give them access right from your smartphone. You can create and share temporary virtual keys (e-keys) with the ones they trust, such as cat-sitter, family, friends and Airbnb guests.
