Model code
⭐ The KEYDIY NB18 is a 3+1-button universal flip remote in a GM-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 B18 shell, the NB18 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 and protocol are written at generation across the same roughly 300–500 MHz tool-set range as the B18. The unit ships without a key blade or battery - both are sourced per job. Built for automotive locksmiths and key shops generating matched GM-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 GM 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.
Tool-set frequency
Frequency and protocol are set during generation across roughly 300–500 MHz, the same adjustable range published for the no-chip B18 shell - no NB18-specific fixed value is published separately.
GM-style 3+1-button flip body
Lock, unlock, trunk and panic in a flip-key body commonly referenced as Chevrolet-type, with a slot for KD universal flip blades (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 GM 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 GM 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 GM-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 GM-family vehicles.
Key shops
Counter service for walk-in GM remote-and-chip replacements without holding model-specific inventory.
Garages & used-car dealers
Preparing spare keys with matched chip data for GM-family vehicles in stock with a KD tool on site.
🧰 Supported coverage
Vehicle coverage is defined by the KEYDIY remote database in the KD tool. Chevrolet and Buick are the confirmed shell associations; Opel is single-sourced only. Cadillac, GMC and Holden 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 B18 (dashboard SKU B01234 - same GM flip-key shell, no built-in chip) or the ZB18 (a Dodge Ram-style proximity/push-to-start smart key on different hardware - not a flip remote). "NB18" bare can also be ambiguous between 3- and 4-button variants across retailers - this listing is the 4-button (NB18-4-equivalent) version.
Some supplier listings describe this chip family as configurable across several profiles - including ones referenced for Peugeot/Citroën, older Honda, VW Touareg/Bentley/Renault/Fiat, and Chrysler/Dodge/Jeep vehicles. That describes the chip's configurable profile range only - this GM-style shell does not physically fit non-GM-family vehicles.

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