The flasher looks nothing like the old flashers. It will be located behind the drivers side lower dash (under the steering wheel). It will be a small black box that is about 3 inches wide, 2 inches deep, and 1 inch thick. It may be somewhat difficult to locate because on some of the GM trucks they actually hide it behind the gauges but to the left of the gauges. in the link 1/2 way down shows location and descriptionhttps://www.gm-trucks.com/forums/topic/104429-where-is-the-turnflasher-relay-on-an-03-2500/

signal light control module LM487 ???? How did you come up with this ??? Your vehicles BCM - body control module controls the hazard an turn signals . Turn Signal/Hazard Lamps
When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation. The driver door switch and passenger door switch also receive voltage from the BCM turn signal supply voltage circuits for the mirror turn signals. The door switches have no function or control of the mirror turn signals other than a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. The instrument panel cluster (IPC) receives the signals to activate the turn signal indicators over the GMLAN serial data system. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators.
Your best bet , take it to a qualified repair shop .

Unless I am mistaken (and it is possible), you typically must have two (2) working original key fobs to program a third.

Is your original not working either? Any custom work to the vehicle recently?

How exactly are the hinges ruined? To change the door on Sierras you drop out the pivots the hinge swings on. If the hinge bodies are the damaged part it's going to cost you money. You will need to get a GOOD body work specialist to cut out the old hinges and re-weld new ones in. Get the specialist to check the body and frame in case the wind has bent something else.

Check all your battery connections. Maybe not a good connection since your key doesn't turn on warning lights and gauges. See if your headlights work to verify a good battery connection.
Any chance you blew fuses? Like a maxi fuse for the ignition switch? Or for older vehicles that used a fusible link to connect battery power with the ignition switch. Keep diagnosing until you get power to the ignition switch (warning lights and gauges working with key ON).
Any chance your battery is totally discharged? Was the alternator working good when tested? If alternator quits working, engine and all electricals will run off the battery for a time until it is totally depleted, then will stall and won't have enough juice to even turn any lights on. Check battery voltage with a multi meter or voltmeter. A good, fully charged battery will show 12.6 volts. If under 12 volts, it may or may not have enough juice to start, but lights will still work some, though maybe very dim. .
