Thanks for the replies. The trunk looked pretty dry, but I can't open it now to look at it. I used a locksmith to open the car. Everything works ok. The car starts and all systems appear to be working. I drove it to the stealership last night. After driving it to the stealership the key fob will work intermittently, but it still a no go for the key itself to work. It will turn , but the lock will not open. The lock will open using the power lock/unlock button in the car. Previously I had intermittent problems with the hatch not opening. I did not get it "fixed" because the dealership said it was not covered under my warranty, but I personally think it's not the lock, but something to do with the the electronics etc. It has pretty much worked since last time I had it at the dealership and now will not open after the Central Locking Pump issue.
