Chevy, GMC, Buick & Cadillac Proximity Keys

Shop GM proximity keys for Chevrolet, GMC, Buick, and Cadillac vehicles at Noble Key Supply. This collection includes smart keys for professional automotive locksmiths, technicians, and key specialists completing spare-key, replacement-key, and all-keys-lost services.

Choose from new OEM, aftermarket, refurbished, and recased proximity keys with different part numbers, FCC IDs, frequencies, transponder chips, and button configurations. Review the complete product specifications before ordering to identify the correct key for the vehicle being serviced.

Chevrolet Proximity Keys

Browse Chevrolet proximity keys for cars, trucks, SUVs, and performance vehicles equipped with keyless entry and push-button ignition. Available applications may include the Silverado, Tahoe, Suburban, Equinox, Traverse, Malibu, Camaro, Corvette, Blazer, Trailblazer, and other Chevrolet models.

Chevrolet smart keys are available with different functions, including remote start, trunk release, liftgate control, tailgate release, panic, and passive entry. Button layout varies by model and equipment package.

GMC Smart Keys

Find GMC proximity keys for compatible vehicles such as the Sierra, Yukon, Terrain, Acadia, Canyon, Hummer EV, and other models. Truck and SUV keys may include specialized controls for the tailgate, liftgate, remote start, or additional vehicle features.

GMC keys with similar cases may operate at different frequencies or use different circuit boards. Match the replacement key’s FCC ID, part number, frequency, chip, and buttons with the vehicle application.

Buick Proximity Keys

Shop Buick proximity keys for models such as the Enclave, Encore, Envision, LaCrosse, Regal, and other push-to-start vehicles. Available smart keys may feature three, four, five, or additional buttons depending on the vehicle.

Some Buick keys share electronic platforms with Chevrolet, GMC, or Cadillac products, but brand and model compatibility should never be assumed. Verify the complete listing before purchasing or programming the key.

Cadillac Smart Keys

Browse Cadillac proximity keys for compatible luxury cars and SUVs, including select Escalade, CT, XT, ATS, CTS, XTS, and other applications. Cadillac smart keys may include remote start, trunk or liftgate release, panic, and passive-entry functions.

Part numbers and frequencies can change between vehicle generations. Confirm all technical identifiers rather than relying on the Cadillac logo, case design, or button arrangement alone.

OEM, Aftermarket, Refurbished, and Recased GM Keys

Noble Key Supply offers multiple product conditions for different service requirements and customer budgets:

• New OEM GM proximity keys
• Aftermarket replacement smart keys
• Grade A refurbished OEM keys
• Grade B refurbished OEM keys
• Recased GM proximity keys

OEM products contain original-equipment components for their specified applications. Aftermarket keys provide replacement options for supported vehicles. Refurbished keys use OEM components prepared for reuse, while recased keys place compatible electronics into replacement exterior housings.

Review each listing for exact condition information, included components, and preparation requirements.

Confirm GM Smart-Key Compatibility

Before purchasing a Chevrolet, GMC, Buick, or Cadillac proximity key, verify:

• Vehicle year, make, and model
• OEM or replacement part number
• FCC ID
• IC number when applicable
• Operating frequency
• Transponder-chip type
• Button count and functions
• Circuit-board information when provided
• Emergency-blade style
• Programming or renewal requirements

GM proximity keys may look identical while using different frequencies or electronic configurations. Choosing a key based on appearance alone can lead to programming failure.

Common GM Proximity-Key Frequencies

The collection includes GM smart keys that operate at different frequencies, including common 315 MHz, 433 MHz, and 434 MHz applications. Frequency requirements vary by vehicle, production year, and market.

Always use the part number, FCC ID, frequency, and vehicle fitment information together. Matching only one identifier may not be sufficient to confirm compatibility.

Programming GM Proximity Keys

A replacement GM proximity key must be programmed before it can operate the vehicle’s passive-entry and push-to-start systems. The required procedure depends on the vehicle, model year, security platform, and number of working keys available.

Some applications support an onboard procedure, while others require compatible diagnostic equipment, a security PIN, GM dealer software, or another specialized programming process. Newer vehicles may involve additional security authorization or programming steps.

Refurbished keys may need to be unlocked, reset, or renewed before reuse. Emergency blades may also need to be purchased or cut separately.

GM Smart Keys for Professional Locksmiths

Maintaining frequently requested GM proximity keys can help locksmiths respond efficiently to spare-key appointments and all-keys-lost calls. Chevrolet and GMC truck and SUV keys are especially important inventory items for many mobile automotive locksmith businesses.

Because GM uses many similar-looking smart keys, careful identification is essential. Confirm compatibility before modifying, cutting, or attempting to program a key.
