The options are:
- with the key's buttons
 - using the detachable key blade (if the battery in the key is discharged)
 - keyless* (the car detects that a key is within range)
 - from the inside of the car with the door handles and lock buttons
 - with the Volvo Cars app
 - automatic locking when the car is driven.
 
Note
In the event of a collision, the car unlocks all doors for safety reasons. This only happens if any of the safety systems have deployed.
