Pluto T6 – A Promising Contender with Growing Pains

The battery pack is removable (while the lock stays on—there’s a small capacitor to keep settings for 30 seconds). Full charge takes 4 hours via micro-USB (yes, micro-USB in 2026, not USB-C—a dated choice). A spare battery is $25. I’d recommend buying one if you go with this lock.

The Pluto T6 arrives in a sturdy, minimalist box. Inside, you get the main lock body, a magnetic strike plate, two physical backup keys, a rechargeable lithium battery pack (rated for 6 months), mounting screws, and a quick-start guide. Build quality feels decent but not premium—the zinc-alloy body has a slight matte finish that resists fingerprints, but the keypad buttons have a little more wobble than I’d like. That said, for the price, it’s acceptable.
