Suggestions for a entry door deadbolt please?

[Richard Durant]

Dear members,

I would like to see if anybody has a good suggestion for the following case.

Please see the picture of the gate; as you can see, there is a deadbolt but it can be reached from the other side as it is at arm length.

Would you have any suggestions?

Here are my idea so far:

1. Install a steel grid in the inside (I am not thrilled by the look it will create and one could also simply cut the grid - not likely to happen though)
2. Find a mechanical deadbolt with code for both side (I don't think I can find one that will fit within the tiny square)

Note:

• It is a safe neighborhood
• It is for a primary house (fire regulation not as important, but still, one should not have to spend life saving time finding a key to exit if there was a fire in the house)

Thank you for your input
