Battery you need – https://amzn.to/2lPBOoJ

Once the new battery is in its just a matter of screwing the circuit board back in and everything else will just click back together. Now you have a fresh battery. You shouldn’t have to reprogram the keyfob it should just start working again if the battery was dead so just click the buttons to test.
Hope this helps some people out.

To program the remote transmitter(s) without using Worldwide Diagnostic System (WDS), follow the procedure outlined below.

operation.

programming status has been enabled.
3. Turn the ignition switch to ‘OFF’ position.
4. Remove the key from the ignition switch.
