You will need to use the valet switch (programming/override button) to perform the programming procedure. It is possible to perform programming without the valet switch but you would need to access the receiver under the dash. We have a troubleshooting procedure for how to do this that we can provide upon request.
There are 2 button styles for this remote but the two styles are the same remote. We mix them together since they are the same. Style 1 is as pictured with button 4 being remote start. Style 2 is with button 4 being trunk instead.
