I'm aware of how to link fobs, starting off with

1. Closing then locking the door using driver side panel
2. Inserting key in and out of ignition 6+ times (within 10sec) until hazards blink, verifying success

BUT my hazards never do so. I've been attempting to pair these fobs for a little over 2 hours now with no luck. I've tried moving onto the next step, ignoring the fact my hazards never blinked.

• ​​​​​​​Insert key and turn to ACC and (within 5 seconds) press any button on fob ONCE and await for hazards to flash

This step was successful in which my hazards flashed upon press of a button. However, upon taking key out, unlocking my door, and stepping out (or closing the door) of my car the fob would not work. Anyone have any ideas??
