Before you buy Every worry, handled.

The questions everyone asks, answered plainly, because peace of mind starts before you buy.

What type of doors can a digital lock be fitted on?

Simpled smart locks can be installed on most main doors and gates Materials such as wooden, metal, plastic, sliding doors and glass You can send your existing door/gate photos for further assistance to our support team at support@simpled.tech.

Does it include the Gateway? Do I need a Gateway?

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

What happens if I lose my physical key?

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

My batteries have completely run out. What can I do?

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.

The touchscreen of the lock seems reflective. Can fingerprints be left on the lock, making it easy to guess the password?

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.

Are both sides of the handle weatherproof and suitable for use on gates?

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.

Your question not here? Call +44 20 7096 0094 (Monday to Friday, 9am to 5pm) or send us a photo.

  • Great company that care. I used them on my first airBnB property and have now rolled them out to two more. The after sales service is what really stands out. Advice, spare parts, tech support all 100% ?

    Owen Werakso · January 2026

  • Very reliable and support is fantastic. They have everything in order and you can feel it in their service and aftermarket. Different and refreshing with great products, highly recommended.
