Why Did a Symbol Car with a Lock Appear on My Dashboard And it wont Start?!

But The Thing is that the Owner Manual I have is for Cobalt Sedan and My is basic and i don't know if it's the same steps ?

Thank You For The Suggestions

I Will Contact The Chevy Dealer because I don't Seem to get Content Theft Detrrent Disarm

And Is Chevrolet Still Doing Recalls for Cobalts?

Thank You Very Much I Just Called The Chevy Dealer and Made an Appointment because it Had 2 Recalls.

And Jim You think With Ignition Switch and Ignition Cylinder Change is Going to Solve the Anti Theft Lock?? I have my car at the Chevy Dealer.

Oh okay I understand now Thank You Very much for your help Once Agian,Jim.

Sorry to Bother Jim But before I took my car into the Dealer I Had 2 Separate Keys for my Car One Would Open the Car (locksmith made) and the other One with the Chevy Label to Turn On Car and Chevy Told me My car turns On good but that they Can't open the Trunk They Told me to Pick up My Car Tommorow.. Any Suggestions?

Well I'll Check it Out When I pick it Up and see What's the Deal, Thanks Jim.

Hello Jim I went to the dealer and they told me the car didn't turn on with the ignition switch and cylinder they had gotten confused with another cobalt thinking my car turned on.. Well this time I went the Symbol on the Dashboard(Anti Theft lock) was now blinking which it wasn't before.What can I do?!

Yes i was Really Upset because they suppose to do everything.. And no the car won't turn on Only The Radio and dashboard lights and Headlights when I try turn it on and like I told you only the anti theft lock symbol stays there blinking.. My uncle said that he would call someone he knew that could reset car computers you think that you would be a good thing to do?

I'm going to let him do a diagnosis on the computer and see what the real problem is.

Jim the actual problem was the fuse box and relays That were burnt i had the auto electric come and They fixed the problem i had the fuse box and relays replaced and it works perfectly now!! Thanks For all the Help Very Helpful Jim.

No Worries!

I I had the same problem with my 2007 Chevy Cobalt but my keys are stuck in the ignition did anyone else have that problem

I have a 2007 Chevy colalt. The car won't start. It happened before, after few hours I put the key in the ignition and it started. It happened again not sure what to do. I did see the padlock icon on the dashboard. Can someone pls help

I HAVE OFFICIALLY HAD MY IGNITION SYSTEM CHNGED 2X'S & FUEL INJECTION KIT REPLACED 3 X'S UNDER WARRANTY & THIS MORNING MY CAR SHUT OFF AT A RED LIGHT AND WHEN I FINALLY WAS ABLE TO START IT AGAIN, I RECEIVED THE CAR LOCK SYMBOL!!!!! SOOOOOOOO FRUSTRATED!!!! BEGINNING TO THINK THEY AREN'T ACTUALLY FIXING ANYTHING!!

I just got a 2008 Chevy Cobalt 9 days ago. It was doing fine up until the 7th day, got in it too go to work soon as I crank up a light with a car and lock came on and I lost power and all my lights and gas mileage was going crazy.. I took it too a mechanic shop,they could not even get it to pull a code.so, they intested my battery which was good. Then they tested my alternator, No charge at all. Replaced alternator,now the car/lock light went off, I got my power steering back,also it runs way better than it did!!! I thought it was strange that a new alternator fixed this problem. But I'm thankful that it did!!

This just happened to our 2007 Silverado. Would not crank , security light was on. Changed dlis fuse and light went off and started right up

Its not in the manual, first off, Mine came on when I turned the car off and stated again, it went out. It was a car with a pad lock in it. I've never seen it before.

Our 2009 Cobalt did the same. It’s like the engine totally seized up. Had to have it towed. Dealer says it’s a voltage issue. Threw all sorts of voltage codes. Hoping this fixes the problem.

I took my 2010 Cobalt to a mechanic & he didn't find the problem I had but made it worse. The anti theft lock is on with low fuel & power steering lights as well (they weren't on before) then I put $10 gas but it doesn't read it. The RPM nor MPH meter are working. I was able to turn on the car with the lock on but if I turn it off, it takes a long time to turn back on. Could it be an electrical issue (electrical mechanic said it wasn't last time he checked it) I've been to 6 mechanics & they all hate my car lol..any tips??

2010 Chevy cobalt lockout symbol would not start clean the grounds that are going to the engine block. That is the problem. There are two grounds on the front of the engine block next to The oil filter housing those grounds need to be cleaned. Car started right up. It is a known problem.
