1998 Boxster Immobilizer issues

Hello All, thank you for your guidance. If I purchase the immobilizer, computer, keys and locks, and put all three in my 1998 Boxster, shouldnt that work without having to have them programmed at the deal since all three are coded the same?

Yes, it will function in your car if the parts the same version as your car had. The computer will still have data from the donor car, such as VIN, engine hours, and peak rpm data, unless you have it reprogrammed.

The VIN doesn’t seem to change when swapping out Key/immobiliser/DME. It stays consistent according to my Durametric. I guess that the VIN must be stored in the cluster.

Yes, that will work.

Just be sure to buy the set specific for a 97-99 2.5L Boxster.
