Help car alarm problems!!!

[jmhole]

I have a hornet maxx 1 that I fitted to my surf, and it works fine! except last night I decided to program it so that I had silent arm and disarm as it is effin loud! Anyhow i put in the pin and got into program mode and disabled auto arm with locking then went on to do the arm/disarm chirps, this didnt appear to work so I went out of program mode, but now when i try to put my pin in it says the pins wrong?!?!?!?!?!

Is anyone an alarm fitter??

What have I done?
