Might I suggest you use logmein.com (free version) to remote into your work computer with your laptop? It works great on an android device but it cost like 30 bucks. Its well worth the cost for the convenience. It will save you a lot of money for the key. As a bonus you can utilize it were anywhere you have internet access. I use my logmein everyday to check my buildings from a computer at my office. Hope this helps.
