title: Google Maps Api Key with already created keystore
body: <p>I am adding Google Maps into my application for the first time.
  I have gone through several tutorials for getting the Google Maps API key for deployment.</p>
  
  <p>But every where the first step indicated is to create a debug.KeyStore OR the create our own application keyStore</p>
  
  <p>Then copy our SHA1 and paste it with the package name while generating API Key.</p>
  
  <p>My small doubt is:
  I am giving an Update of my application and added Google Maps in my version 2.</p>
  
  <p>I do have the keyStore of my application that is already live on the play store.</p>
  
  <p>So what do i do now as I already have my key and have to use the same key for the Update.</p>
  
  <p>I dont want to mess up things at the time of deployment.</p>
  
  <p>Please Help.  </p>
