AutoLock
Locks your hybrid car's doors when you drive off and unlocks them when you shift to P — automatically, hands-free.
What it does
Speed-based locking
Doors lock when you exceed the speed you choose: 10, 15, 20, 25 or 30 km/h.
Or when shifting into D
Alternatively, doors lock as soon as you shift from P to D.
Unlock in P
Doors unlock when you shift to P, only with the car stopped.
Manual buttons
Lock and unlock the doors right away from your phone.
In the background
Open it once, then it takes care of the rest, even with the screen off.

Manual Controls & Safety
Instant lock and unlock with single tap
Safety first
- Doors are never unlocked while the car is moving.
- If the connection drops while driving, the doors stay as they are.
- The app only sends door lock and unlock commands: it doesn't change car settings or clear fault codes.
