Can Keys be de-registered

[whinbush]

Ok Gang,
I need to pick the collective brain.
Due to a monumental moment of forgetfulness and stupidity on my part I have a big problem
The other night when I came home after a very long day in the office I put the car in the garage as is normal and let myself in and settled down for the evening.
Next morning I had the " where are my keys?" Moment
36 hrs later and my whole house turned upside down no sign of them.
The worrying conclusion is that I left them hanging in the front door lock and someone is away with them!
I can't be 100% sure but it's a worrying thought.
Front door lock now changed. Tracker on and Stoplock fitted to steering wheel. To top it wife's car parked in front of garage door.
I have put up a keys lost poster offering a reward ( not too much detail ) .
So far no joy []

So finally I get to the question.
My car in question is a 2012 2.7 981 so has the new electronic key.
Can a key be de-registered from the car ?

Or any other good ideas.

Porsche thus far have proposed replacing ECU / Door locks and two new keys. £££££££££ []

Yes, simply take the car and your key fob to the dealer, If you intend to replace the key fob that is missing (so you have two again) get that first and have the recoding done.
Only the keys that are entered with the recode will be retained in the memory so the old key will not activate the unlock procedure, however, the old key would still be able to start the car if the car was left unlocked.

Typical OPC - make as much as they can out of this by proposing the replacement of both keys and the ecu, thats not required - just the recode to remove the old lost key and entering the current key and spare (new) key

I went through a stage of absent-mindedly throwing my keys away. [] Have you tried the searching the dustbin? [8|]

Just a thought! []

Regards,

Clive.

This is incorrect, when the keys are programmed/reprogrammed the old key will be deleted completely with regards to opening AND starting. HTH

However the hidden mechanical key will still allow gain entry but your alarm will go off if this is attempted without opening the car with a programmed fob.

Thanks all,
I spoke to Guildford OPC and they confirmed they can delete the missing key and re-code my spare key plus one new one.
Making the missing key fob useless apart from the actual key part. Cost £ 280 all in.
Expensive but not as bad as I thought.
Yes anyone with the key could get in but that's all.
As the alarm would go off and it can't be used to start the car.
I'm happy with that as I never leave anything in the car anyway.
Add to that she is kept garaged all should be well.
As for the Bin search, trust me it was marigolds on and the whole contents searched.

Again thanks for the input.
