my keys were stolen from me over a month ago and now i need info on if i need to replace the immobilizer cause i dont have any of the keys it came with (learner key, main key or valet key) and the acura dealership is selling a new immobilizer for about $325 and or Key blanks (Main, black and immobilizer) for $49 can i just buy the blanks or do i have to replace the immobilizer unit

 

You will have to buy a new immobilizer kit which will consist of the red learning key and the immobilizer unit since you do not have your original red learning key. If and when you do get your keys program DO NOT use the red learning key ever to start the car if so you will have to buy a whole new kit.
