OPC Key Woes

Hi All, A little bit of advice.

When i got my 2003 986.2 I only had one remote key. After doing plenty of reading about the various options of getting a second remote key, decided to bite the bullet and get my local OPC to supply and do all the work. This is obviously the most expensive option, but I felt it would be worth the extra as quality of parts and re-assurance of a OPC dealing with a older cars alarm/immobiliser etc.

In I went last week and a hour later and £329.65 lighter came out with a new remote key. All good.

Got home and then tried using my original key.....it did not work the remote functions.

Called the OPC, they apologised profusely, and booked the car back in to get it sorted.

So this morning, again a hour later they have come back and said that the all four memory slots in the car's system were full, and that when they programmed the new key it overwrote my existing key. Saying this is a random thing and that they have no control over which memory slot is used (which does not really make sense to me, because if you have 4 keys, loose one, get a new one, there is a one in four chance that it will kill a surviving key?)

The old key obviously still works in the door locks, but starts the car as well - so the immobiliser chip in the fob still works, it is just the remote functions that do not work on that key (they did before).

I was obviously slightly questioning of this, but was told the only way to sort was to find my original key code card (lost over the past 16 years) or get a new key head reprogrammed.

So I have a couple of questions...firstly why would my old key's immobiliser function still work while the remote functions do not anymore?, are they telling fibs when they say the car randomly chooses the memory slot to store the key info (ie: to over writing existing key info) and someone has just made a mistake?, and finally as the invoice clearly states "Coded x2 keys to vehicle" can I throw my toys out the pram and say they have to sort it?

Thanks for your advice,

Antony


 
Yes it is poppy-cock

You have to choose which of the four entries to use. Sometimes #3 and #4 are free. If they aren’t, you have to determine which might be in use.

You do this for both the immobiliser and the remote alarm - so its unusual that one is right and one is wrong.

Even if you did have the 24 digit key for your first key, the chances of it syncing is low.

Thanks KR,

So looks like the mechanic without checking which memory slots was being used, selected one for the remote door locking, which overwrote the exisitng key and a different memory slot for the immobilisor, which is why that stills works.

Makes sense!

Presumably when they connect to the car they can tell which slot is being used by which key...or is that where the problem is...they can't?

Thanks
 
OPC have overwritten the working remote key with the new one - otherwise it would still work
there are indeed four key locations - I'm assuming that you supplied them with the key you had to get the car to them.
They should have checked the working remote key location prior to programming the new one.

I would be inclined to highlight their error and ask them to supply another key as they have rendered the one you already had inoperative.
It was a very avoidable mistake they made.



 
Yes, you can see the identity of the key in the ignition and see where it appears in the table.

It it is an oversight, but a simple mistake.

Thanks, Lee
 
Just wanted to say thanks for the info C2dweller and irb26. Have had a chat to the OPC, they have confirmed the info you gave is correct and they admitted they made errors when programming the new key, so they have agreed to get the car in and get the work done properly so I will have two fully working keys!
