Hi, I bought a van with alarm Z50 Sat1-2 but the cel chip was out of service. I bought him a new chip but he doesn't respond to the messages. Surely they changed the Master code which I don't know. How can I change the MASTER code?
I tried disconnecting the power + internal battery cable and bypassing the bat connector but nothing changed.
