Bay doors and front door won't unlock

I am at a beautiful spot in Carrabelle FL but scheduled to leave tomorrow. Last night we were eating and heard the door lock. Sure enough it locked itself and all of the bays. Each time i shut the door it locked itself even when I shut it gently. 

 This morning it is not locking itself when I shut the door but  only the key will unlock or lock front door and the bay doors will not unlock with the key. 

I have the ESSEX key pad and I replaced keypad about six months ago. This morning  I went ahead unplugged it and reprogrammed the key pad and it makes all the right beeps according to manual but does not lock or unlock anything. Went to key fobs and when I press the buttons on the key fob I can hear and feel the click when I put my hand on the brain behind instrument panel  but that signal is not activating the locks.

Any ideas? Has anyone had something similar happen? Don't understand why the key wont open any of the bay doors. Cant even leave the site until I at least resolve bay doors unlocking because the electric cord and hose have to be put away

If you haven't used the key to lock or unlock the bay doors for a period of time the locking/unlocking mechanism may just be dirty.  I can used the key in my bay doors but it takes some force to open them, not too long ago I actually broke a key off but I had spares and was able to get the piece out.  Once I got the bay door open I removed the inside cover and lubricated the mechanism.  There is still some resistance but usable.

One of my bay doors seems to be more troublesome then others.  My doors swing down and the latch is at the bottom.  I drilled a hole through so I can put a screw driver up from below to unlatch as a safety as a last resort in I can't get it open

I recently had my Trimark system fail, and lucky for me, all the bay door electric actuators failed unlocked!

When the actuator motors get power for too long, they fail in which ever position they were in, and they are stuck solid! If Essex uses the same bay door actuators Trimark 'used', your never going to get them to move with a key.

When I replaced the module and new keypad, I removed all the bay door actuators so I wouldn't find myself in the situation your in.

Hi Ben:

So do you think the best bet is to get the ones that are  stuck shut  and that I cant access from another bay  will have to have the lock tumblers removed by a lock smith? I will then be able to open them  and drive it but just not be able to lock them.  I guess there are a few once I get one bay open  I can crawl to from another bay and open them from the inside.

May not help but the door has 2 spring loaded pins, in the front door jam,  that provides the power to the door lock. Make sure they move freely and come out when the door is open.

Yeah, the covers on the inside of the doors have to come off, a couple of screws holding the electric actuator , and the latch rod.

Do'able while laying inside a bay, but very uncomfortable!

What made me decide to remove the electric actuators was looking at my front bay. PS has the Aqua Hot mounted about 7" from the door, and DS has the fresh water tank about the same distance. 

Those actuators fail closed, your not getting in there!

Trimark now sell actuators that are supposed to be thermally protected, so they kick out before the motor has a meltdown.

Unfortunately, they are not a direct screw in replacement, and I would have to fabricate adapter plates for each door to make them fit and operate properly.

Update on the problem. It appears as Ben said the actuators were in the locked position. I was able to go through the hole in the bottom of the electric bay where the AC cord for shore power comes out. Reaching up through there I was able to take of the backing plate to the lock and found the actuator frozen in the full lock position . I was able to bend the actuator rod enough to open the door and then removed the actuator and now the lock works fine with the key. I was able to access two other compartments that were also locked by Crawling through a couple of other compartments. Same story . Actuator frozen in the locked position - no 12 volt current present at the moment.  I removed those actuators and disconnected the power on the three doors that were unlocked so now I am able to travel. Problem is the front electrical bay is locked and I have no access to get to the backside of the lock without cutting a hole in the floor!!  Without access to the relays I can't fix anything. I have disconnected the key pad and probably will the remote module as well before leaving. Has anyone else had this problem?  Is there another way to open the bay door lock with the actuator frozen in the locked position? put current to the frozen  actuators but no response.
