1. Why I Wrote This LOCKSTAR Smart Door Lock Review UK
My name is Asif. I live in a rented flat in Stratford, London.
In January 2026, I lost my keys. Again. Third time in four weeks. I searched my entire flat. Under the sofa. In my coat pockets. Inside my bag. Nothing.
I called my landlord. He said, “That is your problem, not mine.”
I called a locksmith. He charged me £120 to open the door and make a new key.
Three weeks later, I lost my keys again.
That is when I decided to buy a smart lock. But I had one big problem. I am a renter. I cannot drill holes in the door. I cannot make permanent changes. I cannot lose my deposit.
So I started searching for a LOCKSTAR Smart Door Lock Review UK because I saw this brand on Amazon UK. I also looked at Yale, Nuki, and Ultion. Every brand had something missing.
| Brand | What Was Missing |
|---|---|
| Yale | No fingerprint unlock. WiFi gateway costs extra £69. |
| Nuki | No physical key. Very expensive. |
| Ultion | WiFi gateway costs extra £80. The app is weak. |
| Aqara | Does not fit UK doors properly. Very few reviews. |
Then I found the LOCKSTAR Smart Door Lock on Amazon UK. It had 1,700+ reviews and 4.7 stars. Fingerprint unlock was included. WiFi gateway was inside the box. Physical keys were included. Price was £174.78.
I bought it.
Now 8 months have passed. I use this LOCKSTAR Smart Door Lock every single day. My landlord still does not know. My deposit is still safe.
I am writing this LOCKSTAR Smart Door Lock Review UK so other renters do not go through what I went through.
2. What Is Inside The Box – Important For UK Renters
This is the best part about the LOCKSTAR Smart Door Lock. Everything comes inside one box. Yale and Nuki make you buy three or four separate boxes. LOCKSTAR does not.
Open the Amazon UK box. You will find:
| Item | Quantity | Why This Matters For UK Renters |
|---|---|---|
| Smart deadbolt lock | 1 | The main lock unit |
| WiFi Gateway / Bridge | 1 | Yale charges £69 extra for this – LOCKSTAR gives it for free |
| Fingerprint keypad unit | 1 | Rare in the UK market |
| Key FOB | 2 | Keep one in your bag |
| Key cards | 2 | Keep one in your wallet |
| Physical keys | 2 | Nuki does not give physical keys – LOCKSTAR gives two |
| Screwdriver | 1 | You do not need to buy this separately |
| Drill piece | 1 | You will not need this (UK doors fit without drilling) |
| Mounting screws | 4 | Extra screws |
| AA batteries | 4 | Ready to use immediately |
| User manual | 1 | Read it before installation |
Important for UK renters: The drill piece is inside the box, but you will not need it. Most UK doors (UPVC, composite, wooden) already have a standard lock hole. I did not drill anything. I only used the screwdriver.
Did I buy anything extra? No. Everything was inside the box. Yale charges £69 extra for the WiFi gateway. LOCKSTAR gives it for free. That is why I decided to write this LOCKSTAR Smart Door Lock Review UK – because the value is unbeatable.
3. Installation – How Hard For A UK Renter
I installed it myself. It took 35 minutes. I did not call my landlord. I did not drill a single hole.
Step by step from my Stratford flat:
Step 1 – Remove the old lock.
My old lock had four screws. I used the screwdriver that LOCKSTAR gave me. I kept the old lock in my cupboard. When I move out, I will put it back. That takes 15 minutes.
Step 2 – Install the LOCKSTAR Smart Door Lock.
I put the new LOCKSTAR lock into the same hole. It fit perfectly. No extra drilling. No damage. My landlord will never know.
Step 3 – Connect the WiFi gateway.
I connected the gateway to my BT router. I use Plusnet broadband. The LAN cable came inside the box. I plugged it in. The green light came on. Done.
Step 4 – Download the app.
I went to the Google Play Store. I searched for the LOCKSTAR app. I created an account. I verified my email. I scanned the QR code.
Step 5 – Register fingerprints.
I registered my thumb. I registered my wife’s index finger. I registered two guests.
Step 6 – Turn on auto lock.
I set the auto lock to 5 seconds. Now the door locks itself after I close it.
Installation complete.
What does my landlord think? He still thinks I am using the old lock. Nothing has changed on the outside of my door. This is why every UK renter needs to read this LOCKSTAR Smart Door Lock Review UK before buying.
4. LOCKSTAR Key Features – What Works Every Day
Fingerprint Touch ID
This is the best feature of the LOCKSTAR Smart Door Lock. Put your finger on the sensor. The door opens in one second.
My fingerprint works 9 out of 10 times. My wife has dry fingers. Her fingerprint works 7 out of 10 times. Sometimes she needs two or three tries.
For UK renters: Fingerprint locks are very rare in the UK. Most smart locks only give you a keypad. LOCKSTAR gives you both. That is why this LOCKSTAR Smart Door Lock Review UK is important – you need to know what you are getting.
Keypad Code
The keypad has a backlight. You can see it at night. You can create multiple codes.
| Code Type | Who Should Use It |
|---|---|
| Permanent code | You and your partner |
| Temporary code | Guests, cleaners (24 hours only) |
| One-time code | Delivery person |
Physical Key Backup
Never forget this. Smart lock batteries can die at any time. When that happens, you need a physical key.
The LOCKSTAR Smart Door Lock gives you two physical keys. I gave one key to my neighbour. He is an Indian uncle who lives next door. I trust him.
5. 7 Ways To Unlock This LOCKSTAR Smart Lock
No other smart lock in this price range gives you this many options. Here is why this LOCKSTAR Smart Door Lock Review UK is different.
| Method | Does It Work? | When I Use It |
|---|---|---|
| Fingerprint | ✅ Yes | Every day, every time |
| Keypad code | ✅ Yes | When my hands are wet |

| Key FOB | ✅ Yes | Inside my bag |
| Key card | ✅ Yes | Inside my wallet |

6. LOCKSTAR App Review – Honest Opinion
The good things about the app:
- The app is free to download. No subscription fee.
- You get real-time notifications when someone opens the door.
- You can see who opened the door and at what time.
- You can create and delete codes from anywhere. Why? Because the WiFi gateway is included in the box.
The not so good things about the app:
- The interface looks old. It is not modern like the Yale app or the Nuki app.
- Some menu options do not apply to this lock. This is confusing for new users.
- The voice guidance volume is very low. You can barely hear it.
My honest verdict: The app works. It does the job. But do not expect Apple-level design. I am keeping this LOCKSTAR Smart Door Lock Review UK honest because you deserve the truth.
7. Does This LOCKSTAR Smart Lock Fit UK Doors?
Yes. This is very important for this LOCKSTAR Smart Door Lock Review UK.
UK doors have standard sizes. The LOCKSTAR Smart Door Lock fits:
- UPVC doors (most common in London flats)
- Composite doors
- Wooden doors
- Flat entrance doors
Before you buy: Measure your existing lock hole. Standard UK sizes are 54mm or 70mm. The LOCKSTAR lock fits both sizes. If you are not sure, message the seller on Amazon UK. They will help you.
8. Price Breakdown – Is £174.78 Worth It?
Let me show you what you actually pay for each brand. This is the most important part of this LOCKSTAR Smart Door Lock Review UK.
| Brand | Lock Price | WiFi Gateway | Fingerprint | Physical Key | Total Price |

- Fingerprint works fast. One second and the door opens. This is very rare in UK smart locks.

11. 5 Things I Did Not Like
I always keep my reviews honest. This LOCKSTAR Smart Door Lock Review UK is no different.
- The app needs improvement. The interface looks old. Some features in the app do not work with this lock. New users get confused.
- The voice guidance is very low. You can barely hear it. Not a big problem, but worth mentioning.
- No Z-Wave support. This lock will not work with SmartThings, Ring, or Hubitat. If you have a smart home hub, this lock is not for you.
- Fingerprint can be picky. Dry fingers sometimes need two or three tries. It works 90% of the time, but not 100%.
- The instructions could be better. The paper manual is okay. Watch the YouTube video instead. That helps more.
12. My Landlord Experience In London
I did not ask my landlord. And my landlord still does not know.
Here is why:

If you want to ask your landlord: Show them this LOCKSTAR Smart Door Lock Review UK. Tell them, “No drilling. No damage. The original lock goes back when I leave.” Most landlords in London will say yes.

I learned these tips from my own experience. Read them before you install your LOCKSTAR Smart Door Lock.
- Keep your old lock safe. You will need it when you move out. Your deposit depends on it.
- Watch the YouTube video first. The paper manual is okay, but the video is much better.
- Test everything before final installation. Connect the WiFi gateway. Test the fingerprint. Test the code. Then install the lock fully.
- Place the WiFi gateway near your router. Do not put it far away. The signal matters.
- Create backup codes. Give one code to a neighbour you trust. Just in case.
