If it locked you out it would start fine, run for 5 seconds, and then stop, with a flashing yellow light on the dash.

If this is not what's happening then your issues likely lie elsewhere. Many many things it could be: best and quickest bet is to track down a VW-specific scanner and see what the diagnostics think.

Check the usual things, starting with the fuel system, fuel filter clean and completely full and primed, no leaks anywhere. If you have fast crank and compression it should start immediately and run, unless the diagnostic codes are showing some particular fault in the system. When was it last running good? how long ago? what happened in the meantime? Did it sit for months? Just changing a battery should not cause the car not to run. I changed batteries twice in my '05 over 15 years and it never caused an issue with running.
