Anyone have any idea what the dealer charges to make keyless entry?

You mean program your keyless control?
What year is your TOY? let me know then I will help.
Program the remote is easy. If you know how to open the door and close it then you can program it. As long you have correct the FCC ID on the remote control.

Thanks, I had to purchase keyless entry after the purchase, we found out that it did not come with the truck.
