Probably not; sorry. Sony can tell you for sure. (See below.) If not, you'll want to obtain a remote.
First try Sony (use the contact information at https://www.contacthelp.com/sony/customer-service). 0r try https://www.remotes.net/. For used, I recommend http://www.searchtempest.com/,* which will provide many useful filters, will let you search locally or country-wide and even globally, and covers Craigslist, eBay, Amazon, and many other sources.
*For SearchTempest, you may want to use a free tracking program like https://www.followthatpage.com/, to save you from having to repeat your search over time.
