IDX Broker Maps not working? Update your Google Maps API key

IDX Broker posted this about how to fix IDX Broker Maps by updating the Google Maps API
The steps below MUST be completed or the
Google maps on your website will cease to function.
Google is making a change to the way they allow their maps to be embedded into websites. The maps used on your Map Search page and Results pages probably use Google to run and will need to have their API Key updated in order to continue to function properly. This is a process that IDX Broker cannot complete for you, but below are some simple Step By Step instructions to take care of this update quickly and easily. Please contact the Support Team with any questions you may have.
You may have already updated your key once before and gotten a Google V2 key. The following steps will instruct you on getting the newest V3 services whether you currently have a V2 key or no key.
Step 1
Go to the Google Webmaster Tools Console, here: https://code.google.com/apis/console and log in.
Note: If you do not have a Google account already, you will need to create one. A Gmail account IS a google account and will work for logging in on this site.
Your Control Panel may look like this:
You may or may not have any services listed in the column on the right. If you have ever updated your Google Maps Key before, you will likely see, as in the example above, a service called “Google Maps API v2”. If you have never updated your Google Map Key you may see nothing in this column. In either case, proceed to Step 2.
Step 2
Click on “Services” from the left navigation bar.
Scroll down until you find “Google Maps API v3” on the list and click the switch to the “ON” position.
If you already have a v2 key turned on, it’s ok to leave it on as well.
Step 3
Click on “API Access” in the left navigation bar.
This screen shows your actual API Key, it looks like a long string of random letters and numbers. Copy the API Key from this screen, be sure not to pick up any spaces before or after the Key.
Step 4
Log in to your IDX Broker Control Panel. Click on the My Preferences tab and then Global Preferences. Scroll down to the Map Options section.
Paste your Key into the Google Maps Key box in this section and select Yes for “Use Google V3 API”.
Note: If you already had a V2 key in your Google Webmaster Tools account, the V3 key may be identical to the V2 key.
Click on Save Changes when you have pasted your new V3 key.
