Question about 2005 Dodge Durango
I had both of my key fobs start intermittently not work. Sometimes the key fob would unlock the car, sometimes it wouldn't. I assumed a low/dead key fob battery, so I replaced it but still had no luck.
So I finally broke down and paid the Dodge Dealer $100 diagnostic fee for them to reprogram the keys (that's what the dealer said would fix it). Now it turns out that they are saying the entire IR control module is inop. I asked the teck what his diagnostic computer actually said was wrong with the control module and he confessed that it didn't actually check the module, but he says that because the keys wouldn't take the programming that it "must" be the IR control module. Which they said will cost me $425 plus they said I needed 2x new keys to go along with it at $200 each.
I find it a little fishy though because I tried the manual reprogramming myself and the IR control module must be "talking" to the keys because it sees the chip in the key to start the car and when I tried to reprogram it myself by following the owner's manual instructions - the key goes through some of the sequence by setting off chimes inside the car.
Usually these kinds of electronic modules usually completely fail or work fine. Does it seem likely the problem is the IR control module? If so, is this something I can order aftermarket and save money?
Thanks in advance! I have the same problem with my 05 Durango. Neither of the key fobs work anymore. First it was intermittently and now nothing. I haven't taken the car into the dealer yet just because of this problem - I want to find out as much as I can so they don't try to screw me over. I almost ordered new keys for almost $500 - I guess either way this is going to be an expensive problem. What the hell happened to the $30 key fobs?!
What I find confusing is the designation 'IR' which is applicable to TV and stereo remotes but have never heard of it used for automotive locks.
It stands for 'Infra-Red' and this is only effective with 'line of sight' applications.
I know every one I've ever owned could be operated without the vehicle even visible as long as the range was not more than 50-70 feet.
These systems use radio frequency signals modulated by digitally coded signals to prevent 'one remote fits all.'
It would be interesting (as long as your patience doesn't wear thin) to find out how you have resolved this.
Mr. Massengill gave good advice since the battery contacts are now made so cheap that they won't donate a few microns of gold to them. Most I've seen were tinned at best.

I have had problems like this and it was caused by a light film of dirt on the battery contacts in the key fob. I took a 3M kitchen scrub pad and lightly rubbed the contacts on the circuirt board of the fob and put the battery back in and it worked. I thought the problem might be caused by the warm enviroment of a pants pocket where the fob is usually kept when not in use.
