Keyless entry on GM vehicles ranges from simple remote-only fobs to full proximity-based passive entry, and knowing which system your vehicle uses determines what replacement or upgrade options actually apply.

Remote Keyless Entry (RKE)
Traditional remote keyless entry requires pressing a button on the fob to lock or unlock the doors, and is the standard system on many older and base-trim GM vehicles.

Passive Keyless Entry
Passive systems detect the fob's proximity automatically, unlocking as you approach and often allowing push-button start without ever removing the fob from your pocket — a feature typically reserved for higher trims and newer model years.

Frequently Asked Questions
Can I upgrade from RKE to passive keyless entry?
This typically isn't a simple aftermarket upgrade since it requires different vehicle hardware and wiring designed in from the factory, so it's generally not practical to retrofit.
Why did my keyless entry suddenly stop working?
A dead fob battery is the most common cause, followed by a fob that's fallen out of sync with the vehicle or a receiver module issue.
Do all GM vehicles use the same keyless entry frequency?
No — frequency and chip type vary by model and year, which is why matching a replacement transmitter to your exact vehicle specification matters.
Is passive entry more secure than button-press RKE?
Both use encrypted rolling codes for security, though passive systems introduce their own considerations like relay attack risk, which is a broader industry topic rather than a GM-specific weakness.
