Yes this is a new key as the previous key would hang up and difficult to turn at times.
I cranked the key and then just released but the security light did not stay on. I had to do this 3,4,5 times to get the security light to stay on. Then, the light did not go out after 10-12 minutes.
The cylinder was purchased at the dealer and was taken to a locksmith who made the key. It is an ilco key. The locksmith commented that this cylinder had been replace before and he thought they must have gotten out of junkyard as the code on the outside of the cylinder was different than how the internal parts were set.
There is nothing printed in the metal.
We disconnected the security system and that didn't solve anythiing either.
In the 10 minute relearn, the security light doesn't flash and in the 30 minute relearn the light doesn't go out. Does that give you any clues?
There is an u1000 code present
