Send command to lock or unlock a vehicle

PUT 
/vehicles/:registration/central-locking

This function requires a specific fitment by Cartrack. You can remotely lock or unlock the vehicle by sending the commands "UNLOCK", "UNLOCK_0", "LOCK". A device is installed in your vehicle and reproduces the keyfob signals.

  • "UNLOCK": this command turns on the keyfob in the car and uses it to send the unlock command. The doors can now be opened. The keyfob stays powered up, the user can turn on the engine.
  • "UNLOCK_0": this command turns on the keyfob in the car and uses it to send a different set of unlock command. The doors can now be opened. However, the keyfob will be immediately powered down, the user won't be able to turn on the engine.
  • "LOCK": this command turns on the keyfob in the vehicle and it uses it to send a lock command. The doors are now locked. The keyfob is powered down immediately after, the engine can't be turned on.

Not all vehicles and devices are compatible with this function.

To prevent duplicate commands, the same command cannot be sent to the same vehicle while a previous one is still being processed (up to 30 seconds). In that case the API responds with an HTTP 409 error and a Retry-After header indicating the number of seconds to wait before retrying.

A 200 response means the instruction was queued for the terminal. A vehicle that is not on your account, or that has no active contract on a hardware type this API supports, answers 404. When the instruction could not be sent at all, because the vehicle has no terminal on its active contract or the terminal cannot currently be reached, the API answers 422 and nothing reaches the vehicle.
