Burglar Alarm Fix
I suspect this is a switch problem - mechanical switch bounce causing multiple entries of the same number despite only one key press. Common especially on keypads where the same digits are the ones that are repeatedly pressed which wears them out. My suggestion - change the code to a different PIN number, not reusing any of the digits in the current PIN, so that use are using more reliable switches that have not been battered with over use.
Apologies for a sensible suggestion in a post response to a very funny article. What can I say - I'm hard-wired as an engineer and problem fixer.
