Looks like somebody found some videos on lock bumping and figures it'd be a good way to get into that shutter.
Not being funny mate but I wouldn't waste my time. I don't wanna jump to conclusions and accuse you of anything, for all I know you lost your key and just wanna save some money... but your brief post and lack of information has me a little suspicious. Apologies if I'm wrong, but even if that is your lock it's not a good idea to take matters into your own hands. You'll put a lot of time and effort into it and end up just calling a locksmith anyway, so save yourself some time and just call someone who actually knows what they're doing.
Here's the deal. Bumping locks isn't as easy as it looks, and it isn't amazingly reliable either. Especially when you've never done it before, the lock is sideways and extremely close to the ground, and you're using a home made key that you made based on a picture you found online of a completely different key. You have no idea how many pins are in the lock or what the spacing is, you're not gonna get that information from us, and you're probably not gonna be getting your hands on the right blank anyway. Those shutter locks are all pretty similar but they do have more than one profile.
Even if you knew the exact blank you needed, a locksmith wouldn't just give it to you anyway so you'd be wasting your time if that's the way you were gonna go about it. If you do manage to get your hands on the correct blank and decide to give it a go then please film your first attempt for us, cos we all love a bit of comedy.
