Stereo & Electronics - Keyless remote: 16245100-29

I've been looking for a second keyless remote on eBay, and found that GM made 2, 3, and 4 button versions of the same remote for our cars.

Does that sound right?

Does anyone have a factory remote that has less than 4 buttons?

Thanks.

GM uses the same remote for many cars. The versions with less than 4 buttons are for other vehicles. The missing button is the hatch release button (I dont know if convertable f-bodies have this button either). Models without an alarm also dont have the "panic" button.

The model number in your title is the model number of the remote that I have. Its a 4-button remote.

You want part number: 16245100-29

That is the part number in the thread title.
