Immobilizer Compatability from year to year

[TNT79Bronco]

Ok. Did the shaving of the tab. Got it all reassembled. Quick question.....

Does the ignition switch have to be replaced because of the different frequency? I know there is a little black box attached to it, that is part of the security system.

Also, the battery was dead. Charging it now. The windows went down, but would not go back up? Hmmmmmmmm. Any ideas. Haven’t really dug into it.

Also, the car seemed like it wanted to turn the starter. Made the typical clicking sounds associated with a dead battery.

More later....

Are you sure the immobilizer is good (because of the windows)?
The frequency applies to the transmitter only (for locking/ unlocking, opening trunk).
