No Starter

The car lights inside and out seem dimmer than usual, but we tried charging the battery and it didn't change anything. The anti-theft and service engine lights come on when I put the key in the ignitiion and try to start the car, and, yes, the anti-theft light stays on and blinks the way it should when the car is off and locked. The clicking noises seem to be from everything that is not turning on the way it normally would. The car was working fine right before the brake replacement, would the battery go down in a couple of hours? Thank you.

You might try locking the car manually and letting it sit for a minute or two then unlock it using the remote. I had a simular experience when to many of the remote buttons were pressed before deactivating the first instruction. Ie. Pressing the panic button then pressing the lock and the start before clearing the panic, it runs down the battery and locks the computer until you can get enough power in the system. Disconnect the ground and reconnect after a couple seconds
