ERA Protect Smart Door Handle review
ERA Protect Smart Universal Door Handle
By Tom Calder
Fingerprint access for up to 50 users and a 9V backup supply are useful multipoint-door-specific features, and it's tested to PSTI, the UK's product security standard for connected devices. But stock across every UK retailer we checked was unusually patchy at time of writing, so treat availability as unconfirmed until you've checked directly with a retailer.
- Best for
- Households with a UPVC or composite front door on a multipoint lock who specifically want fingerprint entry on the handle itself.
- Skip it if
- You need something you can buy and fit this week

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Fingerprint recognition for up to 50 users plus two encrypted key cards included
- Tested to PSTI, the UK's product security standard for connected devices, and GDPR compliant per the manufacturer
- 9V backup power supply if the main batteries fail
Worth knowing
- Stock was inconsistent across every UK channel checked, sold out direct from the manufacturer, listed as discontinued by one retailer, and unavailable on the sourced Amazon listing, so confirm availability before you commit
- Replaces only the door handle, not the multipoint lock's gearbox or cylinder, so the insurance-relevant mechanism is whichever is already fitted
- Batteries are not included in the box

Our review
A complete handle set for a lift-to-lock multipoint door that reads a fingerprint or key card outside and keeps a thumbturn inside, with ERA's Wi-Fi hub in the box for remote unlocking. The thing to know first is that ERA's fitting guide has you take the cylinder out, so there is no keyhole afterwards. It suits a uPVC or composite front door where fingerprints matter more than a key.
What it is
ERA's model DHAEP1 replaces both handles on a multipoint door. ERA's launch release describes fingerprint recognition for up to 50 users, an encrypted key card (two are supplied), e-keys issued with two-factor authentication, geolocation unlock and spoken prompts. ERA says fingerprint and card data are encrypted and stored in the handle, and that the product is GDPR and PSTI compliant; PSTI is the UK's security law for connected products, in force since April 2024, covering passwords and update periods, not physical strength.
Fitting, and what comes out of the door
The installation guide's first step is to remove the existing handle and cylinder: an ERA operating cam goes into the hole the cylinder came from, and a drive bar links it to the inside thumbturn; the multipoint gearbox stays. Afterwards there is no cylinder and no keyway outside, so a flat battery is answered by the 9V contacts under the external handle, not a key, and ERA's own closing advice if you are locked out is to call a locksmith. Fixing packs cover three door-thickness bands, the lever must point toward the hinges, and ERA says steel-skinned composite doors may need the self-drilling screw supplied. Fit it with the door open and unlocked, and test both ways before leaving.
Day to day: locking, batteries and the hub
Locking is still a lift of the handle, which ERA calls deadlocking; after an app, fingerprint or card unlock the handle must be pushed down within 30 seconds or, ERA's manual says, it re-locks for security. Inside, you turn the thumbturn towards the hinges, then push the lever down. Five failed fingerprint or card attempts put the reader into a one-minute lockdown, though the app can still unlock during it. Power is four AA cells, not supplied; ERA's guide estimates six to eight months, suggests a change every six, with about 50 spoken warnings first. Use a 9V alkaline, not zinc-carbon, for the backup. The Wi-Fi Connection Hub in the box takes USB-C power and, ERA's manual says, needs to sit within Bluetooth range of the handle, about 5m; without it, control is Bluetooth at the door, which is also what remains in a power cut: the handle and cards run on their own batteries while the hub stops with the router.
How it compares
The Yale Conexis L1 is the obvious rival: also a full handle for lift-to-lock multipoint doors (Yale asks for 92mm centres), also fitted in place of the cylinder, also four AA cells with a 9V backup, but Bluetooth only unless you add a module, card and tag entry rather than fingerprints, and a BSI Kitemark to TS621:2018 that ERA does not claim. The Yale Linus L2 takes the opposite approach, clamping over your existing cylinder with Wi-Fi built in and leaving the key working. All three are on the smart locks page.
Insurance, standards and getting out
The ERA material we read makes no BS 3621, TS 007, PAS 24 or Sold Secure claim for the handle. Because the cylinder comes out, any star rating it carried goes with it, and what remains for an insurer to assess is the multipoint gearbox and this handle; ask before fitting. For escape, ERA's manual has you turn the inside thumbturn and push the lever, but it does not say how the handle behaves with flat cells, so keep spare AA batteries and practise getting out with everyone in the house; see what to do in a house fire.
Availability and support
ERA backs the handle with a two-year guarantee from completion of installation and four years of critical security and firmware updates from the software's major version date, with a UK helpline. When we checked, ERA's own online shop did not list the handle at all, and everything it did list, spare key cards included, was marked sold out, so confirm stock with a retailer first.
Our verdict
Choose it if you have a lift-to-lock uPVC or composite door, want fingerprints for a family or a cleaner without a keypad on the wall, and are comfortable having no keyhole. Look elsewhere if you want a key as a fallback, a BSI mark, or something you can order today without checking.

Does the ERA Protect Smart Universal Door Handle keep a key?
No. ERA's installation guide removes the cylinder and fits an operating cam in its place, so the outside has a fingerprint reader, a card reader and 9V backup contacts, but no keyway.
What happens when the ERA smart handle batteries go flat?
Hold a 9V alkaline battery to the contacts under the outside handle, unlock with a fingerprint, card or the app, then change the four AA cells in the inside handle straight away, as ERA's manual says.
Does the ERA smart handle work without Wi-Fi?
Yes, at the door: fingerprints, cards and Bluetooth in the app all work locally. Remote unlocking needs the supplied hub, powered and near the handle.
Will the ERA Protect handle fit my door?
ERA describes it for lift-to-lock multipoint locks on uPVC, composite and timber doors. Its three fixing packs cover doors 44 to 50mm, 58 to 65mm and 68 to 75mm thick, so measure first; a door between those bands is not covered.
