Judging by the instructions for your tracker, which we have https://gps-trace.com/en/devices/tk-star-tk915#instructions, it does not have the ability to change the IMEI number.
“123456″ looks like the default password used for SMS commands for the tracker TK-Star TK915.
Tell me, for what purpose do you want to change the IMEI of the tracker? Changing it may lead to the fact that if the number matches the number of another tracker, then problems may occur with receiving incorrect data from another tracker in your account, and vice versa, your data may begin to go to another person.
