Sounds like the chip in the key is not recognising the transponder unit or vise versa when you turn the ignition on initialy . Take the steering wheel cowling cover off to make sure the plastic block connector is tight on the back of the transponder unit behind the ignition barrel . These sometimes work loose, Failing that it might be the key itself (THEY DONT LIKE BEING DROPRD) or a faulty transponder unit which TECH2 will show up .
