Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.

Common questions
Can you program a Blazer key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
