On two occasions, I could not unlock the hatchback. What could be the issue? on 2008 Honda Fit

Could the problem be with the remote or with the lock itself. The first time the key would not work but it did the second time.

Sometimes they will pitch a FIT!! Try a little lube spray on the latch, WD-40 will work. Spray it down good, ALL moving parts involved.
