Porsche installed the 996/ Boxster Immobilizer - M531 Immobilizer CLU (Central locking Unit/ Immobilizer) in a vulnerable location under the driver's seat, making it prone to water damage. Leaving the convertible top open during heavy rain, clogged rain drains, or bad sunroof seals will flood the car interior and sadly the first thing that goes bad is the M531 Immobilizer Central locking unit CLU.

Once the CLU gets wet, there is no reliable way to clean it as the corrosion will start immediately and eventually the system will stop working.

This severe damage will cost hundreds or even thousands of dollars to correct at the dealership.

WE CAN HELP YOU! Our exchange service will get you back on the road saving you hundreds of dollars. We will provide you with a Brand-new Immobilizer unit "Never Wet" and we will exhaust all possibilities to save the programming of your remotes.

We can also provide you with new remotes and Key cut service. Take advantage of the best service available.

We include a bottle of DeoxIT D-Series to clean any corrosion on the Immobilizer harness connector.
