Chevrolet's anti-theft technology has gone through several generations over the years, from the resistor-based Passlock and PassKey systems on older models to modern proximity fobs on current Silverado, Equinox, and Malibu models. Can-Lock Security replaces and programs Chevrolet keys and fobs across this range.
Chevrolet Key Systems by Era
| Era | Typical System | What It Means for Replacement |
|---|---|---|
| Older models | Passlock or PassKey (resistor-based) | Requires matching the vehicle's specific resistor value |
| Mid-generation | Standard transponder keys | Requires chip programming to the vehicle |
| Current models | Proximity fobs, push-button start | Requires fob programming to the vehicle's security module |
Why This History Matters for a Lost Key
Chevrolet's Passlock and PassKey systems, common through the 2000s and into the 2010s on many models, work differently from a standard transponder chip — they rely on a specific resistor value built into the key. A modern proximity fob, by contrast, communicates electronically with the vehicle rather than using a resistor at all. Knowing which system your specific Chevrolet uses matters for getting a replacement working correctly the first time, and it's something we identify before starting any work.
Common Chevrolet Key Situations We Handle
- A lost proximity fob with no spare available
- A fob that's stopped responding, often a battery issue
- An older Chevrolet key with a Passlock or PassKey system needing replacement
- A key broken off in the ignition or door lock
- A used Chevrolet purchase with an unknown key history
Checking the Simple Explanation First
If your Chevrolet's fob has stopped responding, a dead battery is worth checking before assuming anything more serious. This applies to proximity fobs specifically; older Passlock-equipped vehicles don't typically use this kind of battery-dependent fob.
What to Have Ready When You Call
Your Chevrolet's model and approximate year, proof of ownership such as registration or insurance, and your Vehicle Identification Number if available, which helps confirm exactly which key system your vehicle uses.
