2007 Ignition Key - Transponder?

We just purchased an 07 Aveo and only got on key. The car has remote entry built into the key, but I'm wondering if it is a transponder key. I'm trying to get another key made and am having problems finding one.

The car has remote entry built into the key, but I'm wondering if it is a transponder key.

I'm confused.....is it a key with an attached key fob(keyless entry) or is this all built into the head of the key?

Look at your owner's manual......check out the theft system......If it is a PassLock system, then it is just a blank key.....

Yes, it has keyless entry and the fob is built into the head of the key, but I can't seem to find a definitive answer on whether there is also a transponder in the key.

I did check the owners manual but all it says is the vehicle may be equipped with an ignition disable.

Daughter just bought an '07 Wave, same car. If your key has a lock/unlock function, the key doesn't have a transponder and a regular, cheap normal key that costs $2.95 to have cut will work.

Apparently (from what I can figure) there were two kinds of ignitions for these cars, one with a transponder key and one without. The electronic lock/unlock key sets the ignition disable/alarm when you lock the doors whereas the transponder key enables the ignition whe you insert it.

Be aware, and I can't rememebr the exact scenario, but with the lock/unlock key, the doors will lock themselves after a certain time, 30 secs or so if the key is removed from the ignition. So don't take the key out and chuck it on the seat with the windows up :-)......Mike

Local Ace ordered a key blank and it works great. It turned out to not be a transponder key.

Thanks for the heads up on the auto lock. We've noticed that as well. All the more reason to make sure we had an extra key!
