98 Blazer wont start security flashes

[preferredrecovery]

I am having problems getting my wifes 1998 S 10 Blazer 4x4 LT to start, the truck was stolen and the column was damaged, I bought a replacement steering column from a junkyard out of an identical 98 blazer and popped it in, the trucks starts and shuts right off and the security light on the dash is flashing, also the interior lights seem to stay on all the time. Any info on how to reprogram the truck to the new column would be greatly appreciated if that is possible. Thanks, Mark.

the passlock sensor is in the ignition/steering column.....


PASSLOCK Reprogramming Auto Learn
You must perform a Passlock™ Learn Procedure if any of the following components have been replaced:

Passlock™ sensor
Body control module
Powertrain control module
Vehicle control module
Both of the above modules except for the Passlock™ sensor must be programmed using their own vehicle configuration. See the individual module service manual section.

There are 2 types of Passlock learn procedures:

A 10 minute procedure which requires a Techline Terminal and a Tech 2 scan tool PASSLOCK Reprogramming Seed and Key .
A 30 minute procedure which requires a scan tool used in order to clear codes. This procedure is listed below.
30 Minute Procedure
Ensure that the battery is fully charged.
Use a scan tool in order to clear the Passlock™ DTCs.
Turn the ignition switch from the OFF position to the CRANK position, and then to the RUN position. The vehicle will start and then stall.
Leave the ignition ON until the security telltale turns OFF in 10 minutes.
Repeat Steps 3-5 for 2 more times (3 times total)
The Passlock™ controller will learn the new data on the next start attempt.
Use a scan tool in order to clear all DTCs.
