My friend is having a problem with his 05 colorado. It will crank but as soon as it cranks it dies then it displays a lock symbol, Any ideas on what it is and how to fix it?

all battery and ground lines/connections tight? I have the same issue with mine, however I relocated the battery and I think my connections for the extensions are loose. I just wiggle the wire and it fires up. also are the battery terminals clean?

security on the ignition switch may be bad . Take it to a dealer and get checked out.

my 05 did the same thing and it was the ignition switch. and it was onlty at the dealer for a month before the figured it out. it doesnt show up on the scanning tool they use. the had to put a code recorder in the truck and drive it around till it did it again.
