Over the past few months I've had to crank my ignition for serveral mins before it would start. It won't locl/unlock doors or turn on dome light unless I can get the car started. The key will get stuck in the igniiton unless I can get the car to start.

A: Hello there, you have a few different fault...

Hello there, you have a few different faults going on with your 2007 Chevrolet Impala. A vehicle should not have to crank long before it starts unless there is a fault. Given the codes you have listed there are a few common causes such as a faulty security module, key transponder failure, key fob battery, or a faulty fob. The EVAP system leak is a different problem most likely and has a few causes. They are, a leaking gas cap, leaks in the vapor line, charcoal canister, fuel tank seal, or a vent solenoid. If you would like, a qualified technician such as one from YourMechanic will be able to diagnose these faults by performing a [vehicle inspection (https://www.yourmechanic.com/services/75-point-safety-inspection) and make any repairs required.
