Can you program a key or fob I bought online?
Car Keys · Answered by Lightning Lock & Key, Truckee–Tahoe’s locksmith since 1996.
The short answer
Often, if it's genuinely the correct part and a virgin (or compatible) unit — we'll verify compatibility before you count on it.
The full picture
Online parts are hit-or-miss: wrong frequencies, locked used fobs, clones of clones. Sometimes the bargain works; sometimes our supplied part is cheaper than two failed orders.
Every situation has its wrinkles — a two-minute call gets you a straight answer for yours, and phone estimates are always free: (530) 308-6643.

Can a locksmith make a car key with no original to copy?
Yes — that's the all-keys-lost job: the cut is generated from the vehicle itself and the transponder is programmed to the car, typically right where it sits. Full answer →
What's the chip in my car key actually for?
It's a transponder that must answer the car's radio challenge before the engine will start — the immobilizer anti-theft system standard on most cars since the late 1990s. Full answer →
My key turns but the car won't start — is it the key?
Quite possibly: if the dash shows a key/security light, the immobilizer isn't recognizing the chip. A reprogram or properly programmed replacement key fixes it. Full answer →
