I have a 2005 2500 with the factory KE system. I have tried to add a third KE transmitter to the system and when I add one, it knocks another out. Is there a limit of 2 KE transmitters at any one time?

 

A 2004 will accept up to 4. It may have changed for 2005 but I doubt it. How are you doing the programming?

 

I just read the part of the manual about programming. It says that once you enter programming a FOB it erases all FOBs and all FOBs (new and old) have to be reprogrammed/relearned. So, do the lock,unlock,panic sequence for programming for ALL FOBs.

 

This is correct, I have 4 on my 05

 

I just bought a remote for my keyless entry today because i did'nt get any when i bought it used.

how can I tell if mine supports it?? its an 03 quad cab and it has power doors / windows

 

I had heard that if you have power locks/windows and there is only a keyhole on the drivers side (not on the passenger side), then it has the keyless entry. But, if you do not have a working fob, you have to go to the dealer to get the first one programmed, then you can do the rest using the owner's manual.

 

ya mine just has a key hole on driver side.. how much would the dealer charge to programm the first one?

 

I contacted two local dealers when I had mine done, one told me it would take about 45 minutes( I think he was hinting at charging me 45 minutes of labor charges), and the other offered over the phone to do it free. Guess which one I went to. By the way, it only took about 10-15 minutes max.
