GM Transponder Key Programming With a Working Key
Updated 2026 287 vehicles 1997–2017 under a minute per key
This procedure covers 287 Buick, Cadillac, Chevrolet and GMC vehicles from 1997 to 2017. Check that yours is listed below, then follow the steps.
Need the fob itself?
Pick your vehicle to see replacement fobs on Amazon. Match the FCC ID on your old fob before you buy.
Not sure which fob is yours? Find your year below for the exact FCC ID and part number.
On this GM vehicle you can program a new transponder key yourself using a key that already starts the engine. It takes under a minute per key.
Before you start
- A key that already starts the engine
- Your new key, already cut
- 1Insert a working key that starts the engine and start the engine.
- 2Turn the key to OFF and remove it.
- 3Within 10 seconds, insert the new key and turn it to ON — do not start the engine.
- 4Wait for the security light to go out. That means the key is programmed (it can happen so fast you may not see the light).
- 5To program another key, repeat from step 1.
Takes under a minute per key.
Tips & troubleshooting
- If your vehicle has no security light (some 2004–2007 Grand Prix, Bonneville, and Impala), leave the new key in the ON position for 10 minutes and 45 seconds to be sure it programs.
Which fob does your vehicle take?

Find your vehicle below: tap your year for the exact fob it takes — FCC ID, OE part number and battery — or "Shop fobs" to browse replacements for that model.
