What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Have the removed system's splices and interrupted factory circuits traced with the correct wiring diagrams. Record engine and security-system faults with suitable equipment. Restore the documented factory wiring before considering programming or replacement parts.

Here is an example:
Key Chip Programming (Passlock):
Step 1: Insert the new key and attempt to start the engine; it will likely stall.
Step 2: Leave the key in the "ON" position (do not remove it) and observe the SECURITY light. It should stay on or flash.
Step 3: Wait 10 minutes until the security light goes off.
Step 4: Turn the ignition to "OFF" for 5-10 seconds.
Step 5: Repeat steps 1–4 two more times (total of 3 cycles/30 minutes).
Step 6: On the fourth attempt, the truck should start.
Key Fob Remote Programming:
If you are trying to program the keyless entry remote (fob), use this method:
Close all doors and insert the key.
Press and hold the UNLOCK button on the driver’s side door panel.
Turn the ignition ON, OFF, ON, OFF (do not crank the engine).
Release the UNLOCK button; the doors will lock and unlock.
Hold LOCK and UNLOCK on the fob simultaneously for 15-30 seconds until the doors cycle again.
Turn the ignition to ON to exit.
