The alarm would cause the car not to crank, and the alarm horn would sound. You can try unlocking the car from the trunk lock to disarm the alarm. But crank and no start could be a bad ignition switch. Do the dashboard lights stay on or go out while the key is in the crank position? They should remain "on". Worn ignition switch could cause the car to crank but not start.
Is the battery , battery cables , and connections all good ? The ABS and the traction control lights being on wouldn't have anything to do with not starting . The check engine light should be on with the key in the on position , should stay on till the engine is cranked over . The battery is under the rear seat .
Sounds like the anti theft system is active m try this process. Turn the key on. Do not attempt to start. Wait 10 minutes. Turn key off. Turn key on. Wit for theft light to go off. Now attempt to start.
Won't start how ? When you turn the key to the start position does the engine turn over ? A engine cranks but doesn't start an run Or a engine does not crank - no crank - no start ! Two different problems with different diagnostic paths .

I had something similar happen on my 2004 CTS. The car would not crank, and I recall the security light was on the dash. The key could be turned off, but not quite far enough to be removed.
The key can be removed by sticking a small pin or screw driver in a hole under the steering column... maybe 2 inches from the actual steering wheel. I recall there is a small cover or plug in the hole that needs to be removed.
You can let it sit and occasionally try to start it. My did start once more.
I ended up having it towed to the GM dealer and they replaced the ECM for about $500? That took care of it for a couple years, until I recently sold it.
Antitheft or Security system failure is a common problem on GM vehicles. Every time you put your key in the ignition, the vehicle's security system reads the signal from your key to make sure it is OK to run. When it receives the "correct key" signal, the security system allows the starter to turn over, and/or the fuel injectors to function and your car works like it normally does every day. If you were to use a different key, or try to hot wire it, the system would shut down these parts of your car, thus making the vehicle completely immobile. This is GM's way of preventing vehicle theft. The problem is that the system is known to fail quite commonly. It has been failing consistently for around 30 years. When it fails, two things can happen. First, you turn the key and nothing happens at all. Lights work, radio works, windows work... just not the starter that you need to start the vehicle. This is a "starter immobilizer". Second, you turn the key and the vehicles starts just fine, but then stalls in 2-5 seconds. This is a "fuel immobilizer". It literally cuts off the fuel injectors and stalls the vehicle to immobilize it. These are normally, but not always followed by a light on the dash that says SECURITY or ANTITHEFT. These lights are to inform you of the system's failure to collect the information it needs from your key to the computer. If your security/antitheft light is on, odds are you will be stranded soon, if not already. Remember that the security system controls the security light. If the system is failing, the light may never warn you of the failure. There is a lot of info on this site that you can read up on. http://vatspasslockpasskeysecurityhelp.yolasite.com/
