A 3.4 DME will have to be programmed to work with your immobilizer, and to enter your vehicle's VIN. The VIN is a problem during emissions testing when the tester sees a different VIN than your car's tag.

If you use the 3.4 DME and immobilizer, your key fobs will have to be replaced (unless you have the codes).
