Sidewinder keys for Audi

I am taking a crack at the Audi world. Please help me through it. I really need to know if your model has the immobilizer system. The audi parts catalog says ALL of them have the immobolizer, this is not true. Before starting your car, insert the key, turn it on, and look for a light that looks like a car, it will only be on for 3 seconds, if you turn the ignition of and on again, it will not light up. The key has to be removed from the ignition before it will read it again. Even if you do not want to order keys, let me know what year and model you have and if you do or do not have the immo system. email mark1service@comcast.net  thanks


CONTACT US by clicking here to order a flip key, please include your vin and model, also include a picture of the key pointing to the right please

Sidewinder Audi key application 1997 to 2007

This guide will be updated as information and applications are verified. Audi does not
have a comprehensive application guide or chart. Nor is their parts application of these remotes complete or specific.

Please understand any remote for that year group of Audi can be matched to any Audi in the same group.

This is called matching the remote to the car. This is the 2 key procedure and has nothing to do with the key itself.

One remote can be matched to any number of Volkswagens that it is designed to work for. It transmits a digital signal. You teach the car to respond to that unique signal. Have a Audi TT and a Ausi A6 ? it can open doors on all of them, and if the cars are close together, it can lock and unlock all of them at the same time.

Keys are activated. The car sends a pulse through a coil of wire located around the ignition switch. The chip in the key is excited. If the chip has been imprinted with the identity of that car it will see its reflection and allow the motor to run.

Keys previously activated to a different car cannot be imprinted with a new identity. (write only) so used keys will not work on another Audi. Only the remote portion can be used with another Volkswagen.


Most often miss understood is programming. Programming the button REMOTE portion of the key is simple and referred to as matching.
You may need 2 keys. You must be able to lock the drivers door and have the red led alarm light next to the lock button blink. If it does not blink, the alarm does not know the door is closed and will not go into matching mode. Put one key in the ignition switch, turn on, do not start engine. Close the door, use 2nd key, turn door lock and hold in lock position for 10 seconds. Release key to neutral position. 
Press a button on the remote, within 2 seconds press the same button again, the turn signal lights will flash,
this indicates your remote matches the car system and is now recognized. Unlock door remove key from ignition. Remote should now work

Some models you simply lock the door from the outside, and within a few seconds, press a button on the remote. You are done.

The NAA keys are cut by using your serial number to the car (vin dependent) There is a 4 digit key code, unless you are the original owner or you have the black zip tie tag that was attached to the black valet key,  you will not have the key code.  We use an image of your key to verify the code to be cut.

Applications contained here-in are for the Audi models in North America. Audi has 7 markets worldwide. Due to frequency licensing in different countries the remotes will have other part numbers similar to ones here in the USA.

Here is the short version:

1999-2005 Audi TT: any HAA key works, 3 button remote = 4D0837231N , immobilizer system

2001 to 2002 Audi A6: any HAA Key works, 3 button remote 4D0837231P  immobilizer system

1999 1/2 Golf & Jetta: any HAA key works, 3 button remote = 1J0959753F and 1J0959753T.  immobilizer system

2000 to 2001 Golf & Jetta: any HAA key with rfid chip works, 3 button remote = 1J0959753F and 1J0959753T. yes, immobilizer system

2002 to 2005.6 New Beetle, Passat, Golf, Jetta: any HAA key with rfid chip works, remote= 1J0959753AM or DC .  yes, immobilizer system

2005.7 to 2009 Golf, Jetta; newer HAA key 1T0, remote= 1K0959753H, yes, immobilizer system

2005.7 to 2006.2  New Beetle; newer HAA key 1K0, remote= 1J0959753AM or DC, yes, immobilizer system

2006.3 to 2010 New Beetle; newer HAA key 1T0, remote =  1J0959753AM or DC, yes, immobolizer system

note: decimal point refers to month of manufacture 2006.3 means March, 2005.6 means June

Ausi security key system is like the old bug with the cart in front of the horse, you program the car to the key, not the key to the car.

Starting in 1998 with the Audi TT, A4 A6  the key does not have a computer chip, and does not need to be activated. The remote has the oval 3 button HLO 4D0837231Q  (2 button T) . The remote has a swivel loop to attach to a key ring. This remote will not work with A6 Quattro and newer Audi . Some models, the transition date is different, look for the yellow car with the key under it when you turn the ignition on. Picture of 2000 jetta dash, see the yellow car? It only comes on for a few seconds when you turn the ignition on. Using a key not coded to the car will cause the light to blink and the engine will shut off. New beetle has the light at the top center of the speedometer and looks like the New Beetle outline.

If you have a broken key blade, have it copied or code cut and install the blade, back onto your keyless entry unit.
No activation is needed.
If you have a good key blade but the remote is damaged or the flip mechanism cam is broken you can replace the cam key blade holding portion.  Go to the bottom of this page to buy the cam repair kit.
No activation is needed. Separate the remote from the flip key. Pry the emblem off.
Under the emblem is a Phillips screw, remove it. ( I sell replacement cam with pin and emblem) 
The halfs will separate. In the long slot there is a glass pill, looks like a long black grain of rice.
That is the computer chip. Remove the chip from the old flip and install in the new flip. It may be glued in, DO NOT BREAK IT $$$. 
Now the computer will recognize the new flip key as the old flip key. See picture at the bottom of this page.

All flip keys are Main keys.  Valet key is a different blank, series NAA, it is cut the same but will not enter the glove box or trunk lock. There is no such thing as a master key. (that would be like the key housekeeping uses in a hotel and the rooms are different cars) Markings on the key, Huff, w3, etc mean nothing, they are not codes. These keys do not have codes marked on them.

Key logic

I am not here to shove the sale of extra keys down your throat, however the loss of the last or only key to your car will cost you dearly in inconvenience and money. Immobilizer cars may have to be towed to a VW dealer in order to activate a new key if you do not know your skc or have a mobile locksmith who can activate a new key in the field. It is not easy to find someone who can cut the sidewinder key. Do no asume that it can be done just anywhere. (no retail store cuts these keys) Some VW dealers will only cut the keys they sell.

Your car came with 2 flip keys and a valet function key. You can have up to 4 working keys that will start immobilizer cars. Non immo cars can have any number of keys but only 4 functioning remotes.

Any combination of flip, valet, regular main keys are possible for the 1998 to 2004 cars. The 2005 to 2010 cars can only have flip keys and valet keys.

If you have only a badly worn flip key with a loose blade and dead remote. Make that your spare and keep it in the house somewhere. Purchase 2 or 3 new keys and put them into service. Should you part with the car for some reason (wrecked it) the remote portion can be used in another Volkswagen of the same era or resold for another VW owner to use.

Regular main keys and valet keys are worthless to anyone other than the owner of the car they go to. They cannot be reused. Once they are cut, they will only work for that car. The blade cannot be replaced.
