Hawkeye Alarm

My battery went flat and after replacement things had changed. Auto relocking and immobilisation after about 30 seconds happened when it didn't before. I managed to find the codes to stop this. The only thing still different,I hope, is that there is not any delay between switching on the ignition and starting. After this short delay the button on the key has to be pressed to enable starting but now there is zero delay and I have to press the key button every time I start. Does anybody know the code to reset the delay.
