I recently picked up a 2006 Yukon XL Denali. It came only with a single bare metal copied key. How did the factory keys come for these vehicles - are they a one-piece key/transmitter unit, or a separate key and transmitter fob? I see a bunch of transmitter fobs on Ebay, but I'm wondering if that matches what the original factory keys were.

Thanks!

 

The OEM key has a chip in it w/o which I don't think it'll work. Could be wrong on that.

The key fob is separate for unlocking/locking, panic alarm, remote start, etc.

 

Hmm, I just have a bare metal no-name duplicate key, no chip. Hopefully that doesn't mean the previous owner has defeated some kind of protection system.

 

Might check w/ dealer to see if your model should have the chip.

 

Looks like only 2007+ needs the chip; my 2006 does not.
