Vitara locksmith help
 

The passenger side power door lock is being tempermental. When the remote locking doesn't work, the manual key moves but not fully.. this could be an electrical issue.. should I call a locksmith?

yep.. call a locksmith

I will do the same as said but if the locksmith refused to do the work then what would be the right option?

The problem must be with the lock not with the key and you surely need locksmith help for it.
