TextPrologue Key System Launch
1st Generation (RE1)
Launch 2024-2025. Honda's first US-market EV riding on the GM Ultium platform alongside the Chevy Blazer EV. The smart proximity fob wears the Honda H badge and Honda firmware on the user-facing side, but the immobilizer underneath follows GM Global B architecture. Push-button start, rolling-code auth, and a CR2032 cell that occasionally needs a careful auth re-pair after replacement.
Identify Your Prologue Fob
Honda-branded smart proximity fob. Push-button start. Rolling-code auth. CR2032 cell. Standard 2024-2025 spec.
Prologue Key Pricing in San Diego
Pricing covers the fob, OBD programming, Honda server auth, full pair-test. EVs require verified high-voltage isolation before service, included in the price. No trip fee in San Diego County. Standalone lockout $105-$145.
EZ Car Keyz vs. San Diego Honda Dealer
Same warranty terms the dealer offers, parts and programming both. Difference is your Prologue stays plugged in to your Rancho Santa Fe charger and Marco brings the Honda-GM tool stack to your driveway instead of a flatbed run.

GM Ultium Platform Auth Complexity
Prologue inherits GM Global B immobilizer architecture under the Honda badge. Right tool stack matters more than usual. We carry both Honda and GM diagnostic equipment because the fob is Honda-spec but the immobilizer speaks GM. Most shops bail; we do not.
All-Keys-Lost Routing Decisions
Brand-new EV with mixed Honda-GM architecture sometimes requires Honda dealer server time for all-keys-lost jobs depending on VIN. We test the auth path on the truck first. If your VIN is dealer-only that day, we tell you up front instead of finding mid-job.
Fob Battery Replacement Auth Re-Pair
A CR2032 swap on a Prologue sometimes triggers an auth re-pair a Civic owner would never hit. Fob loses sync if battery removal exceeds the keep-alive window. We pair-test on the truck after every battery swap before leaving the Rancho Santa Fe driveway.
Can You Program a Prologue Key Yourself?
No. Prologue requires either Honda HDS or GM Tech 2 with current firmware, plus server auth. Zero consumer-tier DIY path.

Prologue Trivia
The Prologue is Honda's first US mass-production EV, launched for 2024 under the Honda-GM partnership. Honda exterior styling, Honda interior trim, Honda branding on the fob, but every byte of the immobilizer architecture is GM Global B underneath because the car shares its Ultium battery platform with the Chevy Blazer EV. Programming a Prologue smart key means running tools from both ecosystems, which is exactly why some shops will not touch these calls.
