Model code
⭐ The KEYDIY NB27-4 (KEYDIY's own designation: NB27-3+1) is a 3+1-button universal flip remote in an Audi-style flip-key shell, part of the KEYDIY KD NB series and generated with KD tools such as the KD900, KD900+, Mini KD, KD-X2, KD-X4 and KD-MAX. Unlike the plain no-chip B27-4 shell, the NB27-4 carries a built-in super transponder that the KD tool configures at generation to emulate the chip ID the target vehicle's immobilizer expects, so no separate transponder chip needs to be sourced or programmed. Frequency for this SKU is 315 MHz / 433 MHz. The unit ships without a key blade or battery - both are sourced per job. Built for automotive locksmiths and key shops generating matched Audi-family remote-and-chip combinations on demand instead of stocking model-specific fobs and chips separately.
⚙️ Key features
Universal by generation
One blank replaces a wall of vehicle-specific Audi remotes - and their chips. The KD tool writes the remote data and configures the built-in chip together for the vehicle selected from the KEYDIY database.
Built-in super transponder
A transponder chip is built into the shell and configured by the KD tool to emulate the ID class the target immobilizer expects - no separate chip to source or pre-program. This SKU's chip belongs to KEYDIY's ID46/ID47-class NB-series transponder family.
315/433 MHz
This SKU runs a dual 315 MHz / 433 MHz frequency; no NB27-4-specific KD-tool-adjustable range is documented beyond this.
Audi-style 3+1-button flip body
Lock, unlock, trunk and panic in a flip-key body styled for Audi, with a slot for a KD universal HU66-profile flip blade (not included) and a standard CR2032 cell (not included).
💎 Benefits
Leaner remote and chip stock
Carry one NB-series blank instead of separate remote and chip part numbers for every Audi flip-key job, freeing shelf space and working capital.
Generate on demand
Produce a matched remote-and-chip unit at the job in minutes with a KD tool - no waiting on a specific Audi replacement part or chip to arrive.
No dead stock
An ungenerated blank isn't tied to one vehicle or one chip ID - whatever the next Audi-family job turns out to be, the same unit can serve it.
👥 Who it's for
Automotive locksmiths
Field remote-and-chip generation for lock-out, spare-key, all-keys-lost and remote-replacement jobs on Audi vehicles.
Key shops
Counter service for walk-in Audi remote-and-chip replacements without holding model-specific inventory.
Garages & used-car dealers
Preparing spare keys with matched chip data for Audi vehicles in stock with a KD tool on site.
🧰 Supported coverage
Vehicle coverage is defined by the KEYDIY remote database in the KD tool. Every NB27-4-specific source describes this shell as Audi-exclusive. VW, SEAT, Skoda and Porsche were checked and were not found associated with this SKU. Confirm the exact make, model and year in the tool before generating.
Not the same part as the plain B27-4 (dashboard SKU B01248 - same Audi flip-key shell, no built-in chip). The 3-button NB27-3 is a cleanly separate SKU, not an alternate name for this listing. Also unrelated: ZB27 / ZB27-4 (a Chrysler-style proximity smart key on different hardware) and ZB26-3 (an Audi-type proximity smart key, one digit off in numbering but a different product class entirely - not a flip remote).
KEYDIY documents several configurable modes for this NB-series chip family - including ones referenced for Peugeot/Citroën/older Honda, VW Touareg/Bentley/Renault/Fiat, Chrysler/Dodge/Jeep, and Buick/Chevrolet/Opel. That describes the chip's configurable profile range only - this Audi-style shell does not physically fit non-Audi-family vehicles.

🛠️ Programming instructions
Confirm before the job: the pairing procedure, remote coverage and supported chip profile vary by Audi model and year - verify the vehicle and its pairing method in the KD database first.
