Here is a quick video showing me taking apart the key fob, taking the batteries out. I put it all back together and demonstrate the programming procedure.
NOTE: You might not need to re-program the key but I added it just in case. Also you will need to program the key inside the car. Full sequence can be seen here: https://youtu.be/QCUqLTn8l7U
The key fob is a Siemens 433.92 mhz, 5WK4 790/97/98. This information is on the side of the key fob.
Thanks for watching!
