2011 Chevy impala..battery was dead..had a jump start..but radio system want come on now..

SOURCE: 2000 Jetta Radio is dead after a dead battery jump start

Some German cars have anti-theft device inside to make it useless to steal...check at the dealership to see if jumping the battery will activate this(the car thinks its being stolen) .

SOURCE: 2001 Chevy Impala won't start

If the battery has gone dead, it could cause the security system to go into full lock-up mode. If it has locked up the accessories will work after the battery is charged back up , but the power to the starter will be cut off and it wont turn over. You need to do the 30 minute learn procedure. A GM dealer will print it out for you and you can do it yourself. It's very simple if you follow the procedure exact. hope this helps and good luck.

Check the radio fuse? Box is drivers side end of dash(drivers door open)or pass side end of dash(passenger door open)
police models have a connection for the speakers (passenger floorboard under floor mat) to connect the speakers to the police radios.
If they had the speakers connected to their radios,they may have unhooked them and not connected them back to the radio.
The wires are brown,grey,blue and light blue.All into a blue connector.

• A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle. The only way to unlock the radio is by using a scan tool.
