gprs commands for TopFly SOLARGUARDX

I have a Solar Guard GPS that reports well to the platform, but it has a lock and unlock function. At the moment I have only been able to do this via SMS with the following command:
SMS
UNLOCK,U#
U=Password

Do you know how I can do this lock and unlock with a GPRS command?

Thanks in advance

Have you tried from the device popup menu on the map a custom command like: UNLOCK,U#

(or without the #) If that works you could create it as a saved command and bind it to the device.

Thank you very much for everything trace-trace, I was able to send the unlock command by SMS, I first linked clicksend and then created the command and activated the SMS box and then I sent it.
