How to program remote starter rpn 474a - 2002 Chevrolet Suburban

Remote Starters have to bypass the anti-theft software. disconnecting the battery, broke the programming. You will need to take it back to the installer.

Remote starter in valet mode Symptoms: Lock and Unlock buttons work as normal, but pressing Start does not produce any response from the vehicle.
Causes: Someone accidentally pressed the combination of buttons to put the car into valet mode, usually when the remote is in a purse or pocket. Also, many remote car starters will revert to valet mode when the vehicle is disconnected for service.
Hood Pin Has Broken or Failed Symptoms: Pressing Start results in several flashes of the parking lights but no start. If equipped, Lock and Unlock still function.
Cause: In most cases, the under-hood pin switch is broken or corroded.
Remote Control Loses Programming Symptoms: Pressing any button on the remote results in no response from vehicle.
Cause: It is rare, but does happen - in most cases, this is caused by a dead battery in the vehicle or the battery having been disconnected when being serviced.
Remote starters usually have some type of non-volatile memory to retain things like programming features and remote control codes. Like any "computer" device, sometimes they lose memory. When this happens, simply call the store that installed it for you. In some cases, they may be able to tell you how to reprogram it over the phone. Other times, you will have to return to the store for a technician to program it. In any case, this is rare with higher-end remote starters.
Remote is in Second-car Mode Symptoms: Pressing any button on the remote results in no response from vehicle.
Causes: A combination of buttons were accidentally pressed, which put the remote in second-car mode.
Again, this is very rare, but happens from time to time. Many remote car starter remote controls have the ability to start two vehicles. If the remote is accidentally placed into second-car mode, it will not start or operate vehicle #1.
Simply read your owner's manual or call your installer for directions on how to revert the remote back to car #1.

The problem here is the remote start system is not giving out the correct transponder code to the security system, this locks out the starter. As to how you program the remote start I have no clue as to what you need to do.

Remote starters are a bad thing to have because they can short out your wirring and ruin your starter as well.

The remote start feature is part of the body control module. If the door locks are working you have an issue with the remotes or maybe programming. Also check the battery hold down in the remote, it may be loose or broken.
