S3 Remote Key Fob Replacement

[ash_s3]

When i bought my S3 a week ago, it only came with the one key!
So i need to get anouther and get them both reprogrammed so any old keys wont disarm the immobiliser.
A new key from Audi is about £150! + programming
But my mate at VW said he can programe it for a tenner for me as a foreigner
Seen some keys on ebay but how do i know which will work?
The one i have at the moment is a flip key with 2 buttons - lock and unlock
but alot of the ebay keys have 3 buttons!
help please!
thanks

Mine came with the three button keys, the third button opens the boot. I believe key programming is a dealer job, but I could be wrong.

You can program the key to lock and unlock the car yourself but the transponder immobiliser is not a diy job. You definately want the missing keys excluded or someone could come calling in the middle of the night

stil havnt sorted the key problem yet!
do i have to get a key with the exact same part number or can i choose any key aslong as it is the same frequency (mhz)
im sure my s3 should have come with a 3-button fob but this one is only 2 just lock and unlock, no boot release

any help would be appreciated!
cheers

i went to the stealers for a new key for my a3, i have the 2 button keyfob, but bizzarely, the one audi did for me was of the 3 button variety.

of course the middle button does nothing, but found it strange that the 3 button one worked.

how come the middle button does not work?
do you know the part number and frequency by anychance?

how come the middle button does not work?

Later A3/S3's (Faclift models 2000>) had a solenoid that operates the boot lid, so you could remote unlock with the third button on the remote.

how come the middle button does not work?

when i say it doesnt work, i mean that theres nothing underneath the button when you press it, so its empty underneath.

It's not that confusing, pre facelift cars had two buttons, post facelift had three buttons one of which unlocked the boot seperately. I would think you can probably use either key for your car as long as it can be programmed to work however the boot button won't do anything.
