I have a 2007 GMC Yukon denali and the fob or key won't unlock my car. So it sits at a store for right now. What is wrong?

Nope. They are both good. What is weird is that the key won't unlock door either.

That's really odd. By any odd chance did you pick up the wrong key???

What happens when you put the key in the door lock? Dose it turn or just do nothing?

Not wrong key.

When I put the key in does nothing. It turns but it doesn't respond

Is it possible that someone tried to steal the vehicle? This is getting weird.

I don't know if someone did. I was in the store. I just know in can't get in it.

From what you have described it is highly possible that someone tried to brake into the vehicle. By any chance dose the vehicle have a key spot on the passenger side? I'm sure that you have thought of that. It's almost time for a locksmith.

So what ever happened? Did you get the problem solved?

I got in my car. However my key will no unlock my door. Still cant figure that one out.

Dose the key offer any resistance or just flop back and forth?

Just flop back and forth.

My gut is telling me someone tried to steal the vehicle. They used a "Slim Jim" to try to get the door unlocked so they could get inside and do God knows what. Anyway, now your going to have to get the door panel off and reattach the door lock rod to the locking mechanism. It's not a hard job. Go to YouTube and watch a video on how to get the job done.

I just got locked inside my Yukon today because I used a replica key that was made. I almost suffocated inside of my garage. I had to break a window to get out to breathe. The alarm was going off and it would not unlock from the inside. I had to call for God’s help. It was a miracle I got out before overheating. I started to panic and could not breathe.

I’m having the same problem with my 2007 Yukon Denali door won’t open with key nor will it unlock automatically. Could it be a problem with the battery?
