🧰 GM Key Types We Replace or Program

Smart Keys & Proximity Fobs (2014–Present)

Modern GM vehicles such as the Cadillac Escalade, Chevy Silverado, Buick Enclave, and GMC Sierra use encrypted Smart Keys for proximity entry and push-to-start.

Common Smart Key Issues

“No Remote Detected” / “Key Not Detected” warning
Push-button start not responding
Lost or stolen Smart Key fobs
Remote start or trunk release not working

We can program new GM Smart Keys onsite, erase lost fobs from your vehicle’s memory, and fully re-sync the immobilizer and BCM (Body Control Module) for complete functionality.

PK3 / PK3+ Transponder Keys (1998–2014)

These PassKey III and PassKey III+ (PK3/PK3+) keys contain transponder chips embedded in the head that must be recognized by the vehicle’s immobilizer before it will start.

Typical Problems

“Starting Disabled” or “Security” light flashing
Car cranks but won’t start
Damaged or worn key
All keys lost

We cut and program PK3/PK3+ keys directly onsite — even when all keys are lost — using GM-compatible immobilizer software.

VATS (Vehicle Anti-Theft System) Keys (1986–2005)

Older GM vehicles, including Corvette, Camaro, Impala, and some Cadillacs, use VATS resistor keys with embedded pellet chips.
We measure the correct resistance value, cut new keys, and program them to match your ignition and security system.

Remote Head & Flip Keys (2005–2020)

Popular in Chevy Cruze, Equinox, Malibu, and GMC Terrain, these keys combine a transponder chip and remote in one.
We repair broken shells, replace buttons, or supply brand-new flip keys programmed and tested onsite.

Laser-Cut / High-Security Keys

Many newer GM vehicles, especially Cadillac, Buick, and GMC Denali, use sidewinder (laser-cut) keys for added security.
Our high-precision cutting machines guarantee exact fits and reliable ignition every time.

⚙️ Advanced GM Key & Module Programming

EEPROM & BCM Reprogramming (All Keys Lost)

When all keys are lost, GM dealerships often replace the BCM or ECM, costing thousands.
At Canadian Locksmiths, we use advanced EEPROM programming to extract and restore immobilizer data from your existing module, allowing new key registration without replacing electronics.

Remote Start & Fob Programming

We program OEM and aftermarket remotes for vehicles with factory or remote-start systems, ensuring seamless lock/unlock/start operation.

Ignition & Door Lock Repairs

Older GM vehicles are prone to worn ignition cylinders or broken key blades.
We rebuild, replace, or rekey locks onsite and sync them to your existing key or newly programmed transponder.

⚠️ Common GM Key & Lock Problems We Solve

“Starting Disabled” or “Key Not Detected” messages
Broken or worn ignition keys
Smart Key won’t unlock or remote start
Lost all keys (EEPROM/BCM reprogramming required)
Transponder not recognized after battery replacement
Remote buttons not working or worn out

We use GM Tech2 and MDI-compatible programming interfaces for secure, factory-level key and module communication.
