2008 ave door ajar jamb switch

[Stormie]

Hello everyone. My aveo's central locking system is malfunctioning.
1. It locks/unlocks from a keyfob
2. It wont lock/unlock when I press the driver side lock when im inside
3. It is supposed to auto lock after 30 secs, but its not doing it anymore.

Is changing door ajar jamb switches can fix this? What should I check first? Pls help if anyone experience this kind of problems with central locking. Thanks in advance

Can't help here but must ask if my 2010 Aveo LS auto is supposed to autolock?
