In case you are in a hurry, the short answer is No.
Google stopped using the keywords meta tags years ago, get people still seem to be trying to leverage these things to get their website “up the rankings”.
The reason Google stopped using them is people generally used them to try and get themselves up the ranking and play the game. They rarely provided much in the way of genuine info that Google couldn’t already get from analysing the data on the page.
Google does however use the Meta Description tag, often (if you have a good quality description) to populate their small excerpt you see on the google page.
So go and spend some time improving and updating the content of your site, but please don’t waste any time coming up with a list of keywords, it’s a waste of time.
