Alarm problem

[jp77]

Good morning everybody.

excuse me for my poor english ( I can read but write is difficult)

I have a UK Spec supra for 15 years and never had any problem with it but a few weeks ago, i moved for a few weeks and the battery dieded . I replaced it with a new one but the alarm went on and I can't disabled it. It is a toyota factory alarm with the 2 butons black and red.

I tried e few things I found in the forum but nothing works 

Could someone tell me how to desable or remove that stupid alarm please, I would like to take it off .

I have seen Mr Matt Harwood seems to know a lot about that alarm so if he could send me a mp.

Thank you to all of you
