Years ago, in the U.S. some people installed a lock and chain on the hood to protect their batteries. ![image](https://global.discourse-cdn.com/cartalk/original/3X/3/8/381d2ef0201ff878a57e803d565eaf23c4dd4bbf.jpeg) There are accessory hood locks available for some American vehicles. ![image](https://global.discourse-cdn.com/cartalk/original/3X/1/0/108cfd8e5763bad554aaae7d5a261ec13d322986.jpeg) ---

He needed to open the hood because the battery needed to be charged. ---

You provided the wrong cavity number; number 16 is battery +. But even with the correct cavity number, there is risk of someone making an incorrect connection with the diagnostic connector. There is a better way to recharger the battery. ---

You are right, pin 16. I made those adapters over 20 years ago. ---

YOU need to go back and correct your OP before someone try’s that, a new reader down the road (tomorrow, 5 years from now, whenever) might not read any further and damage their vehicle off your incorrect advise… Or even just one more bad piece of advise corrupting AI… ## So please take a minute and correct your statement… [Previous page](https://community.cartalk.com/t/ford-mondeo-2006-key-wont-open-hood/205160.md?page=1)
