NPAUTO Key Fob Replacement for Audi A4 A6 A8 S4 S6 S8 TT RS6 Cabriolet 1997-2005 - Uncut Keyless Entry Remote Control Car Flip Key Fobs (MYT8Z0837231,4D0837231E, 4D0837231P)

I lost one of my keys while walking around downtown; it must have slipped out of my pocket. This incident emphasized the importance of having a spare key, and luckily, I had an extra one at home, allowing me to retrieve my car without needing a locksmith's assistance.Subsequently, I ordered a keyblank and fob. Surprisingly, it arrived within two days, even though I hadn't chosen expedited shipping. My local auto key cutter had no issues cutting the blank after I provided both this new one and the original key.Afterward, I easily programmed the key fob to unlock/lock/open the trunk by following the instructions, which can be found through a web search for "How to duplicate key and program key fob for 2001 Audi TT."As evident in the photos, the new key fob closely resembles the original one, with the only exception being the absence of the Audi four-ring logo on the back. The key fob's range is about five car lengths, surpassing the performance of my original.

The car does not recognize this fob remote, it DOES transmit at 315MHz (verified through SDR) but it does something wrong with signaling. I was able to pair remotes from another vendor without an issue.Do not expect the buttons to work.I was able to pair the ID48 pill for the ignition/Immo3 to my car, so it functions as an ignition key.

The FOB arrived quickly. I was able to remove the roll pin holding the key blank in the flip part of the FOB and swap my existing key into the FOB. A quick search on YouTube brought up several videos on the programming on how to pair the FOB with the car. I was able to get the two key method to work on my 2001 Audi A4 Avant Quattro. The programming did render my old FOB inactive, which was already broken. I will need to research the steps to program two FOB's to the car when I order the second FOB.

Great new key reason I’m not giving 5 is because the internals on the oem B5 key does not work in this without modification because they changed the battery layout and size on this key fob but if you use the battery back plate from your oem key it will fit just doesn’t have the same texture and you’ll have to shave down one of the button pin for the unlock button and I wish it came with an Audi logo but I understand why lol but all around great price great quality I’d buy again

Although the description states is was compatible with the correct FCC code for my car, the locksmith could not program the remote to lock or unlock etc… though he was successful in programming the key to the ingition. I should have had them try to program before I had the key cut so I could have returned it.

Excellent price and very quick deliver. Bought car with only one key so this was a great choice to buying from dealer.

Unable to insert my personal key into fob. Attempted to remove blank and place my key instead. Base of my key too broad to fit. Had to return. Otherwise a good value
