928 Key Replacement
1. Key Length
928 keys come in two distinct lengths from the "shoulder" to the tip of the key, namely:
The extra length on the tip of the longer "S-Key" is used to control the optional factory fitted alarm (which were available
from at least 1980).
You can use a short key in a long ignition lock, provided that the ignition immobiliser is either off or disabled.
2. Cutting from the VIN
If the key is worn, then copying a new key from it will only cut you a new worn key. So, cutting from the VIN is the best option if you can
afford to wait. However, your locks must be original (i.e. match the VIN) and the cost may be considerably higher than some key cutters.
You can take your VIN along with proof of ownership to a Porsche Distributor. Expect to pay $115 for a normal key and $150 for one with a
torch in the head. And wait two weeks for the key to come in from Germany.
Alternatively Devek <www.devek.net> is cheaper. Send then your VIN and photocopy of your registration and they will send
you a "normal" key for US$20 or a lighted key head for an extra US$11 (not sure if this includes postage).
3. Sources of Blanks
Cutting from the VIN won't work if the locks have been changed.
Figure out whether you need a long key or a short key.
A locksmith who can cut you a key will almost certainly have blanks.
This is probably the best approach, since they can examine your existing
key before choosing the appropriate blank.
Blanks are also available from Mitre 10. They may not have them hanging
on the wall but will get them for you. About $7. Like a fair bit of the
928, the keys and locks are made in Italy. Silca is the brand name, short
blank number is HU42P.
Blanks may also be found on Ebay.
928 (and other Porsche) keys are somewhat special in their design. Their blanks are rectangular and have to be cut at an angle of 45
to the normal horizontal position. A special adaptor is required to cut the keys on standard key cutting machines.
Only a small number of locksmiths have the required adaptor. It's specific to Porsche, expensive, and business volume is not exactly
huge. Some charge a premium for using it. Some don't.
It's almost mandatory to take your car, or at least the locks, to the
locksmith, as the cut key will almost certainly require 'fine tuning'.
