Through an unusual series of events I recently ended up with my car locked with the fob inside, but I had the actual key. Only to find out the key would not open any of the door locks. I have had my vibe since new, so I know it is the correct key etc. I know at one point this key opened the locks, but it has been many years since I have done so.
Soaking the locks with WD40 did not help. I’m now concerned if I ever have a flat battery I won’t even be able to get into car to pop the hood. What else can I try to get the locks working again?
