Whats wrong with my 2004 chevy malibu?

Question

I have a 2004 chevy malibu and all has been great until one day, i tried to unlock the door with my key, and it would not work. My key does not unlock the trunk as well. Now i have to use the key fob to unlock the doors. What is wrong with my car and/or key?

Answer 1

If you use the key fod all the time the door and trunk lock get dry and don't want to work.You can stop by your local auto parts store and buy some lock spray.You put this in  the lock cylinders and this cleans and lubes them to correct your problem.Best of luck.

Answer 2

Key is worn out.  Dont make a copy of it.  Go to chevy and have them cut a fresh key based on the codes.  They can figure it out from the key you have.
