My remote start works fine, but sometimes my truck won't start with the key. The security light flashes rapidly. So then I just start it with the remote and it starts right up. I only have one key, so I ordered 3 more. My concern in getting the new keys programmed is that my remote start might quit working if they used a key in the security bypass system(since all key codes would have to be erased). The only box I can find is the remote starter itself. There's no key in it. Any ideas?

 

What year and make of truck and what make and model on the remote system
