Passenger door lock is stuck

[RMcG]

Hi,

I have a basic (no electronics or keyless entry) 2008 three door (hatchback) Yaris. For several weeks the passenger door lock has been stuck. I can lock & unlock it and open & close it from the inside. But I cannot unlock it from the outside with a key. I can, of course, open and close it from the outside IF it is unlocked.

I should add, the key just does not turn when put into the lock. It is apparently "stuck."

I have already tried putting graphite, WD 40 and PB Blaster into the key hole. But none of these has worked.

Any ideas what I can do?

Thanks,

R.
