Urgent help needed

Hi
Ok so its a bit silly...I lost my only key to my Cayenne 3.2L V6 2006, fell from my pocket....havent been able to find it in 3 days. I do have a skeleton key which opens up the door.
Called the porsche dealership here in India and they said they will have to order a lockset along with a new key and code the new key in. The lockset consists of the door lock and ignition lock and is priced at $2000.
Now I have come across this on ebay:

Will this just be plug and play....that is i replace the ECU and the ignition lock. Will the remote lock and unlock the doors also?

Doubtful. The ECU i just one of many modules that are both coded and tied to the immobilizer.

Example 1....the locks are through the Kessy module not engine ECU....so the fob buttons will not work.

Example 2....the cluster is tied to the ecu, so after replacement you would need to reprogram.

you shouldn't need to replace the lock cylinder though.....they should be able to cut new key and program that new fob to work with you existing car hardware, should be cheaper than 2k

I cant believe that your porsche dealer is right.

I bought a additional pair of key fobs just in case i lost one or some is not working.

Took the car to the dealer for REPROGRAMMING the new keys.

They ask about 180 euro per key.

The fobs you can find for 60 to 100 euro.

I believe its much more easy than your dealer try to tell you

Ok so what seems to be the best option? That means the ECU thingie is out......so either I talk to the dealer again or call porsche germany???

Ok one more question....If I buy a used remote from ebay and put my key in it and take it to my dealer and say that the remote has stopped working....will they be able to tell if the remote is from another car? I can say I woke up and the car would not unlock and remote would not work.....so maybe they can reprogramme it....but if they know the remote is from another car then they might not.

You can buy key fobs from other cars or new ones. As i know doesnt matter. You have to change the metal part from your key to the new fob and ask dealer to program it to the cars software. I saw it one how they do it with a software like PIWIS. Takes some time but this is the easy solution for you
