Honda Accord 2001 lx stock alarm?

I bought a Honda Accord 2001 lx and the alarm doesn't work on it. I replaced the battery on the remote and it the remote light barely turns on with the lock button and with the unlock button it turns in bright but it still doesn't do anything. I was messing with it yesterday by just pressing the lock button a lot maybe 20+ times and it locked once but it doesn't wanna work anymore. The led light comeint from the main security unit doesn't turn on also. Near the Main security unit it has this little grey button that I have no idea what it does but when I press it and hold it for about 3+ seconds the led light starts flashing in a certain pattern for about 7+ seconds. Can anybody help with this please?!

Hi the only best answer is a Honda dealer if a honda dealer disabled this alarm they did it for a good reason. As they have a network which the dealers communicate over the facts will be on a record as to why this car had issues. So time to take it and get some advice from the honda delear.
