Our verdict
Welock suits homeowners who want a self-installed cylinder lock with nothing to pay each month after the purchase. The fingerprint cylinder costs €119 with monitoring at €0 and a contract of 0 months, and professional monitoring is off, so there is no renewal to budget for.

Pros and cons
Pros
- No subscription attached: monitoring runs at €0 and the contract is 0 months, so there is nothing to renew.
- The app is free and includes Bluetooth unlock with access sharing, so a spare key or code can be issued to someone from a phone.
- Entry price of €119 sits below the smart lock category median of €87.69, so a fitted cylinder costs less than a typical one.
- No installer needed: the model is diy and installation is not required, so the existing cylinder can be swapped out by hand.
- Returns run for 30 days, which takes the risk out of ordering a lock for a door you cannot try first.
Cons
- Professional monitoring is off, so the lock secures the door and shares access but does not alert anyone during an intrusion.
- The range covers smart lock only, so cameras, sensors or an alarm panel have to come from another maker.
- Support runs on email and help centre only, so there is no phone line for a lock that has to be fitted to a door.
- Voice control covers alexa only, so a household built on another assistant will not get the lock into that ecosystem.

Scored 8.8 / 10 by SmartHomeCue.
Who it suits
- Homeowners or renters swapping an existing cylinder who want no monthly fee after the purchase
- People already using the voice assistant listed in alexa elsewhere in the house
- Buyers who want a battery lock that runs on its own, with the model listed as diy
Who should look elsewhere
- Anyone who wants professional monitoring, because that option is off and no response desk is offered
- Households wanting cameras or alarms in the same basket, since the range is smart lock only
- Smart home setups built on other ecosystems, as voice support covers alexa alone
What it does well
Welock sells a single category on this site: smart lock. The featured unit is a fingerprint cylinder, and the range runs on battery power rather than a wired feed, so it suits a door where running cable is awkward. Installation is not required and the model is diy, which means the cylinder is swapped in rather than installed by a tradesperson. The free app covers Bluetooth unlock and access sharing, so a code or a key can be handed to another person from a phone rather than cut into the door. Voice support covers alexa. Professional monitoring is not offered, and the product types sit in one lane, so a household that also wants cameras or an alarm will be buying those elsewhere.
Pricing
The entry price is €119 for the lock itself. There is no subscription layer: monitoring runs at €0 and the contract is 0 months, so there is no renewal date to plan around and no term to serve. The free app, which carries Bluetooth unlock and access sharing, is part of the purchase rather than a paid tier. For comparison, entry prices at the brands alongside it sit lower: The Home Security Superstore lists $13.95, GHome Smart lists $23.99 and Aqara lists £36.98, though those figures are for different products rather than a like-for-like cylinder lock. Returns run for 30 days, which is the main cost protection on a hardware purchase.
Where it sits among rivals
On price, Welock ranks 52 of 70 brands on this site, which places the entry figure in the middle to upper part of the smart lock list rather than at the cheap end. The category median price is €87.69 and the upper quartile reaches €149. On contract length, Welock ranks 1 of 60, and on monthly monitoring cost it ranks 1 of 51, so those two measures are settled before any feature is weighed. The overall score here is 8.8, split into a cost part of 9, an offer part of 8.6 and a trust part of 8.9.
Who runs it
Welock has been running since 2013 and is based in China, which is a shorter track record than some of the long-established names on the smart lock list. Support is offered through email and help centre, so troubleshooting depends on written contact or a self-serve help centre rather than a phone line. For a lock that is fitted into a security door, written support and a returns window of 30 days are the practical safety net, and with installation not required a fit problem is a matter of swapping the cylinder back out.

Frequently asked questions
How much does a Welock smart lock cost?+
The entry price is €119 for the lock, with no subscription layered on top. The smart lock category median on this site is €87.69, and Welock sits below it. Returns run for 30 days if the cylinder does not suit your door.
Is there a monthly fee for a Welock lock?+
No. Monitoring runs at €0, so there is nothing to pay each month. The contract is also 0 months, meaning there is no minimum term to serve and nothing to renew. You buy the hardware and that is the cost.
Do I need to pay someone to install a Welock lock?+
No, installation is not required. The model is diy, and the product is a cylinder that fits into an existing door rather than a wired panel. If you are not comfortable with a cylinder swap, budget time or a locksmith for that part only.
Is there professional monitoring available?+
Professional monitoring is not offered, so the lock is a self-contained device rather than an alarm with a response desk. Monitoring costs €0 and the contract is 0 months, which fits a hardware-only setup that locks the door and shares access from the app rather than watching for intrusions.
Which smart home platforms does Welock work with?+
Voice assistant support covers alexa. The app itself handles Bluetooth unlock and access sharing, so the core functions do not depend on a voice platform. If your household runs another ecosystem, check compatibility before buying, as coverage is limited to what is listed.
What kind of products does Welock make?+
On this site, Welock covers smart lock, so the range is a single product type. If you want cameras, sensors or an alarm panel alongside the door lock, you are mixing brands. That can work, but the app experience will not be shared across makers.
Who do I contact if something goes wrong with a Welock lock?+
Support runs on email and help centre, so you have email and a help centre rather than a phone line. Given that installation is not required, written guidance plus the 30 days returns window covers most early problems. Plan for a slower reply than a phone call would give.
How does Welock compare with cheaper alternatives?+
Welock's entry price is €119, against $13.95 at The Home Security Superstore, $23.99 at GHome Smart and £36.98 at Aqara. Those are different products rather than equivalent cylinders, so the gap reflects category as much as value. Welock's own ongoing cost is €0 on a contract of 0 months.
