When it's cold out, I start my 05 Trailblazer by pushing the "lock" button on the fob 3 times. This past week I touched the brake getting in before the key was in the ignition. The engine died, as it should, but was real hard to restart. When I did get it started, the display on the radio was blank. The radio works, I can change channels with the presets and knob, but nothing displays. Anyone else ever have this problem? Thanks.
