Between the years 1997 and 2005, Porsche installed the Immobilizer computer for Boxsters and 996s directly onto the floor of the car, under the driver's seat. If the car gets less than 1 inch of water the Immobilizer will short-circuit, STOP your car and your Remotes will STOP working, ending in a very expensive repair.

Whether it's because of rain, flood, or clogs in the drain tubes, these Immobilizers are always at risk. The going rate for Labor, Replacement and Reprogramming of an Immobilizer module is above $1,200, and you may loose the programming of your Remotes.


Don't let this happen to you!
