Check all the fuses inside the car. the new battery could have surged and blew a fuse which would cause the key less entry sensor in the car to stop.

My fob and keyless entry system doesn't work correctly sometimes it activates and sometimes it just doesn't. also activate the immobilizer randomly, any ideas?

Based on all the info you have provided I think you need a professional to get involved here, I am not willing to "GUESS" what might be the issue or issues (more likely more than one).
Good luck

I have a 2005 cobalt every time I open the doors the alarm goes off I replaced the battery in keyless entry but they do not work can anyone help?

You may have accidentally broke the controller. They are fragile. The newer cars like yours automatically set the alarm when the doors are locked from keychain remote, or locking manually. New remote, $50-100.

Cannot get either of the lock remotes to work.Have changed batteries several times.Also want to know why alarm goes off when key is used to unlock doors

After replacing the batteries in your key remotes, you need to have the keyless entry module re-learn each of the remotes. This requires a diagnostic tool at the dealership or locksmith.

Keyless entry stopped working on 05 cobalt now i have to unlock door with the key and when i do that the alarm goes off. Help

Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.

Keyless entry

My keyless entry did the same thing on my cobalt. There are two tongs that get displaced. Atleast that's how it is in mine. I find if i hit the clicker off my hand a couple times it works. Sounds funny i know but that's the only thing i've found to work
