Main Caravan Door Internal Child Lock

I understand your issue but please don’t forget that a caravan door needs to be easily opened at all times in case an emergency escape is needed. Personally, I’d be very wary of fitting such a device even if it exists.

If one did exist you would have to drill/screw it to the caravan anyway.

Fully agree with the above but depending on what is to the sides of your door (ours has the 'kitchen wall' with the fridge on one side and the back 'wall' of the rear diner on the other and if so you could use a temporary home child stair gate that is pressure mounted (is held in place from screws that face outwards) or something similar but beware caravans are not as solid as home walls and you could cause damage quite easily and screwing into outside walls is not advisable at all. Caravan doors are also not as wide as the stairs at home. Do you have a door fly screen? or put a large box in front on the door?

There is no easy solution (from experience) other than good parenting and keeping an eye out at all times. They will grow out of it eventually!   

Thinking outside the box - does the door have an opening window?  If so I have a possible solution.  

Thank you all for your suggestions. I'm hoping they grow out of it soon. 

Navigateur Caravanner, no it does not. 

SAS Security products do a cover that fits over the internal door lock preventing it from being opened whilst it's attached. 

Easy to fit and remove for an adult but very difficult for a young child
