So...what the point of an anti-theft system on a stereo? Both my Honda and Ford have one, where if you disconnect the stereo from the battery, you need to enter a code upon reconnecting it, to prove you're the owner and such. So I just replaced the battery in my Ford, and the code prompt came up. Normally it's written in the owner's manual (which most people keep in their cars with them, so that's strike one). Mine however had been ripped out by a previous owner. So I didn't have it. Now, Honda in the UK has a rule where as long as you are a dealer of vehicles (as in, doesn't matter what you sell), if you sell a Honda, you can give the code to a customer. Ford on the other hand says it has to be a Ford dealer. Which the dealer I bought my car from is not. Well, it's Saturday, and because this is the UK, where the free market is viewed as a disgusting side-product of the dirty thing capitalism is, most service centers don't work. So what did I do? I got the serial number from the stereo, Googled it, and had my code in five seconds. So tell me; why is this a thing when a Google search on the serial number will get you what you need?
