The Grisoll LYRA is a fingerprint smart deadbolt with a glass touchscreen keypad and a quiet motorised bolt. It replaces a separate deadbolt above your door handle and turns it into keyless entry, so guest check-ins and family comings and goings no longer depend on keys.
Key features
- Five ways to unlock: fingerprint, touchscreen passcode, swipe card or fob, mobile app and backup mechanical key.
- One-touch locking: a quiet motorised deadbolt locks with a single tap, with no turning or twisting.
- Room for everyone: stores up to 100 fingerprints and 50 passcodes.
- Auto-locking and tamper alerts: locks behind you and warns you of tampering.
- Weatherproof: IP65 rated for exterior doors.
- Simple installation: replaces an existing deadbolt with just a screwdriver.
Will it fit my door?
Check your door first. The LYRA replaces a separate deadbolt on doors with a 54mm cross bore. This set-up is common on internal doors, offices, garages and outbuildings. It isn't designed for doors with a multipoint lock or a Euro cylinder mortise lock, which most UK and European front doors use. For those doors, choose the VANTA, ATLAS or TORO. Not sure? Use our Find Your Fit guide or email us a photo of your door.

Let customers speak for us
This was a straightforward swap for our uPVC door without needing a locksmith. The 40mm size matched perfectly, the reversible latch made the left-swing setup easy, and everything feels durable.
Haven't had a single connectivity issue in eight months of daily use.
The backup key slot is a nice safety feature that shows thoughtful design.
Heavy-duty construction feels like it'll last decades, not just years.
Finally a security upgrade that's both practical and genuinely convenient.
My realtor says it's a major selling point for potential buyers.
Shared temporary access codes with my cleaning service and everything worked flawlessly.
Customer support responded immediately when I had a question.
No more fumbling with keys in the dark - absolutely worth it.
Very reliable, though installation took a bit longer than I'd hoped.
No more anxiety about whether I locked the door - I can verify from anywhere.
This made upgrading our back door to a smart lock effortless. The internal mechanism aligned perfectly, no drilling or adjustments needed, and the door operates smoothly now.
