Security light is flashing and stays on when trying to start the car
Expert:  Jay replied 1 month ago.

Oh.. So the security light turns solid when you turn the key to the ON position?

I am on my way home from work.. Be back online in about 1/2 hour or so. Sorry for the delay...

Thank you.. If the security light is ON solid when the key is in the ON position, that means that the key you are using to try to start the truck is not programmed. So you would need to call a Mobile Locksmith to come out and program the key for you. At the same time, if he can cut another key for you, so that key can be programmed for you as well, you would be back up to having 2 keys for the vehicle.

But that is what you will need to do to resolve your issue I am afraid.

Any locksmith can program the key? I am in Brazil ����
Expert:  Jay replied 1 month ago.

You may want to call around to Mobile Locksmiths to see if they do key programming. Most do now..

I just got a fab that is supposed to be for the car it looks the same as the one I had before. Can I program this somehow to unlock the alarm?
Expert:  Jay replied 1 month ago.

The remote is easy to program. But you need to have a working key to program it.. I have a video on how to do that.. Hang on..

ignore I put the key in and out the hazards flash, I turn the key and the Dash goes on, I press the button on the remote but nothing happens. Is that because it's not a programmed key?
Expert:  Jay replied 1 month ago.

Those steps only program the remote. Not the key. You need a scanner to program the key.
