So I recently lost my keys and had a replacement done, so now randomly when i insert the key, the whole car goes dead, no sound, no lights work and the red security light is flashing, if i wait about 5-10mins the car works again... I called the guy who made my key and he said to just disable to the alarm, how do i go about with that? or how to fix the alarm issue all together? The search option gave me a few links but doesn't seem to have helped. 2003 is300 automatic.
