Serato DJ Pro is a popular software for DJs, and it's great that you're interested in using it. However, I want to advise you against searching for or using license keys from untrusted sources. These sources can often lead to malware, viruses, or other security issues.

If you're looking for a free trial or a demo version, Serato usually offers those options on their official website. This can be a great way to try out the software before committing to a purchase.

Instead, I recommend purchasing a legitimate license key directly from Serato or an authorized retailer. This way, you'll get a genuine key, and you'll also support the developers who work hard to create great software for DJs.
